IMPACT:
Security Bypass, Manipulation of data

WHERE:
>From local network

SOFTWARE:
Cisco Unity Express 2.x
http://secunia.com/product/5151/

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.
