CVE reference:CVE-2006-2166


Description:
A vulnerability has been reported in Cisco Unity Express (CUE), which can be exploited by malicious users to manipulate certain information.

The vulnerability is caused due to missing restrictions in the HTTP management interface during password changes. This makes it possible for an authenticated user to change the password for another user with an expired password (including newly created users with blank/randomly selected passwords).

Successful exploitation may e.g. grant administrative privileges on a CUE module, if the changed expired password belongs to an administrative user.

The vulnerability affects any CUE Advanced Integration Module (AIM) or Network Module (NM) running CUE software versions up to 2.2(2).

Solution:
Update to version 2.3(1) or later.
