Site vulnerabil?!

robertutzu · April 16, 2013

Deci am un site facut simplu html si un formular .php. Astazi cumva, nustiu cum, vad asa ceva:

Edit: nu am nici un form de upload imagini!

Script uploaded:

/public_html/images/run.php:235:

/public_html/images/run.php:236:

/public_html/images/run.php:237:

Intrebare:

Cum a reusit sa urce acel script php si ce pot face sa remediez aceasta problema sau de la ce poate fi?

Cand ma uit sa vad ce facea scriptu hop na, trimitea spam, asta e scriptu:

<DIV id=""></DIV></DIV></BODY></HTML>
<BODY><A href=""><FONT size="5"><STRONG>BEST SPAM TOOLS</STRONG></FONT></A><FONT size="5"><STRONG>  
FRESH TOOLS GOOD PRICE</STRONG></FONT> </BODY></HTML>
<?
function doset() {
        set_time_limit(200000);
        ini_set("memory_limit", "256M");
        ignore_user_abort(true);
}
doset();


if ($_POST['action']=="send"){

        $message = urlencode($_POST['message']);

        $message = ereg_replace("%5C%22", "%22", $message);

        $message = urldecode($message);
        $message = stripslashes($message);
        $subject = stripslashes($_POST['subject']);

}

Poate ai LFI sau RFI sau SQLi sau server vulnerabil. Sunt o mul?ime de posibilit??i..

malsploit · April 16, 2013

uita-te prin loguri. Esti pe shared-hosting?

robertutzu · April 16, 2013

@silvian0 SQli nu are cum nu am baza de date, mai ramane LFi si RFI, serverul nu cred ca e vulnerabil.

@hate.me e dedicatul meu cu whm pe el

Dr.Milf · April 16, 2013

-Cum te conectezi la whm? :2086 sau :2087? Stealer?

-Vezi FTP Server Configuration din WHM.

robertutzu · April 16, 2013

la whm am deny la orice ip doar ip meu static are acces, stealer cam improbabil, bruteforce nici atat am cphulk enabled,

Conectarea e pe :2087 pe https

La ftp server aveam astea pe yes

Allow Anonymous Uploads YES (acum am pus pe NO)

Allow Anonymous Logins YES(acum am pus pe NO)
