Vulnerability Note VU#800227

OneOrZero AIMS authentication bypass and SQLi vulnerabilities

Overview

OneOrZero Action & Information Management System (AIMS) is vulnerable to an authentication bypass and SQL injection.

I. Description

According to the vendor's website:

"OneOrZero AIMS is a powerful enterprise ready suite that includes a help desk, knowledge base, time manager and reporting system supported by a highly configurable and extensible Action & Information Management System that allows you to 'build your own system' on the fly."

AIMS is susceptible to an authentication bypass. An attacker can generate a session cookie for $_COOKIE['oozimsrememberme'] and log in as an administrator without providing a password.

AIMS is also susceptible to SQL injection. On line 136 of lib\ooz_access.php the $cookieName variable that originates from an attacker controllable cookie is passed to a SQL statement without any filtering:

$sql = "SELECT * FROM " . OOZ_SET_TABLE_PREFIX . "users WHERE user_name = '" . $cookieName . "'";
$userResult = DB::query($sql, DSN, OOZ_SET_SHOW_SQL);

 

II. Impact

An unauthenticated remote attacker may be able to bypass authentication or leak database information.

III. Solution

We are currently unaware of a practical solution to this problem.
