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. This advisory is available at the referenced link.
