Cisco Hosted WebEx Meeting Center Configuration Manipulation Vulnerability

A vulnerability in the Cisco Hosted WebEx Meeting Center service could allow an unauthenticated, remote attacker to enable meeting features that were explicitly disabled by the meeting organizer or site administrator.

The vulnerability is due to improper checking of certain meeting parameters when a user joins a scheduled meeting. An attacker could exploit this vulnerability by submitting a crafted request designed to activate a disabled meeting feature or service.

Cisco has confirmed the vulnerability in a security notice and released software updates.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
