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 ? Contacted Vendor No Response
Feb 05, 2012 ? Public Disclosure
Since the vendor did not reply we attempted to create our own
fixes for this issue. The vulnerability exist in ?login2.php?
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.

As I did not receive any emails back from rezahmail@ on how author informed vendor I reported this as https://sourceforge.net/tracker/?func=detail&aid=3488241&group_id=298778&atid=1260461
