SUMMARY

 * A vulnerability in the web-based management interface of Cisco Unified
   Communications Manager (Unified CM) and Cisco Unified Communications Manager
   Session Management Edition (Unified CM SME) could allow an unauthenticated,
   remote attacker to conduct a cross-site scripting (XSS) attack against a user
   of the interface.
   
   This vulnerability exists because the web-based management interface does not
   properly validate user-supplied input. 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.
   
   This advisory is available at the following link:
