Summary
o A vulnerability in the web-based management interface of Cisco Unified
Communications Manager, Cisco Unified Communications Manager Session
Management Edition, Cisco Unified Communications Manager IM & Presence
Service, and Cisco Unity Connection could allow an unauthenticated, remote
attacker to conduct a cross-site scripting (XSS) attack against a user of
the interface.
The vulnerability is due to insufficient validation of user-supplied input
by the web-based management interface of the affected software. An attacker
could exploit this vulnerability by persuading a user of the interface to
click a crafted link. A successful exploit could allow the attacker to
execute arbitrary script code in the context of the affected interface or
access sensitive browser-based information.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
