Summary

Cisco Unified Communications Manager and Unified CM Session Management Edition have a cross-site scripting flaw in their web management interface. An attacker can remotely, without logging in, trick a user into clicking a crafted link to run script code in the interface or read sensitive browser-based information.

Read the original description

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.
