Summary
=======

A vulnerability in the Extensible Messaging and Presence Protocol (XMPP)
service of the Cisco Meeting Server (CMS) could allow an unauthenticated,
remote attacker to masquerade as a legitimate user. This vulnerability
is due to the XMPP service incorrectly processing a deprecated
authentication scheme. A successful exploit could allow an attacker to
access the system as another user.

Cisco has released software updates that address this vulnerability.
Workarounds that address this vulnerability in some environments are
available.
