# Exploit Title: XRayCMS 1.1.1 SQL Injection Vulnerability
# Date: 2/12/2012
# Author: Dr.web
# Software Link: http://sourceforge.net/projects/xraycms/files/latest/download
# Version: 1.1.1
# Tested on: Ubuntu
XRay CMS is vulnerable to a SQL Injection attack which allows
authentication bypass into the admins account. If a malicious
user supplies ' or 1=1# into the applications user name field
they will be logged into the applications admin account.
Jan 29, 2012 \u2013 Contacted Vendor No Response
Feb 05, 2012 \u2013 Public Disclosure
Since the vendor did not reply we attempted to create our own
fixes for this issue. The vulnerability exist in \u201clogin2.php\u201d
on lines 20 and 21.
17  if(!isset($_POST['username'])) header("Location: login.php?error_username");
18  if(!isset($_POST['password'])) header("Location: login.php?error_password");
19
20  $user = $_POST['username'];
21  $pass = $_POST['password'];
If the lines 20 and 21 are changed to:
$user = mysql_real_escape_string($_POST['username']);
$pass = mysql_real_escape_string($_POST['password']);
This will prevent the sql injection from happening in the user name field.
