Name of the Vulnerable Software and Affected Versions Cisco Unified Communications Manager versions (affected versions not specified) Cisco Unified Communications Manager IM & Presence Service versions (affected versions not specified) Cisco Unified Communications Manager Session Management Edition versions (affected versions not specified) Cisco Unity Connection versions (affected versions not specified)

Description The web-based management interface of the affected Cisco products does not properly validate user-supplied input, allowing an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against an interface user. An attacker could exploit this issue by persuading an interface user to click a crafted link, potentially executing arbitrary script code in the context of the affected interface or accessing sensitive browser-based information.

Recommendations For Cisco Unified Communications Manager, update to a version that properly validates user-supplied input to prevent XSS attacks. For Cisco Unified Communications Manager IM & Presence Service, update to a version that properly validates user-supplied input to prevent XSS attacks. For Cisco Unified Communications Manager Session Management Edition, update to a version that properly validates user-supplied input to prevent XSS attacks. For Cisco Unity Connection, update to a version that properly validates user-supplied input to prevent XSS attacks. As a temporary workaround, consider restricting access to the web-based management interface to minimize the risk of exploitation.
