Summary

A vulnerability in the Contact Center Express (CCX) Editor application of Cisco Unified CCX could allow an unauthenticated, remote attacker to bypass authentication and obtain administrative permissions for script creation and execution. This is due to improper authentication mechanisms in the communication between the CCX Editor and the Unified CCX server.

Risk Assessment

An attacker could redirect the authentication flow to a malicious server and create and execute arbitrary scripts on the underlying operating system of the Unified CCX server as an internal non-root user.

Recommendation

Apply the patches provided by Cisco for Cisco Unified CCX. Restrict network access to the Unified CCX server and monitor for unusual activity.

Original NVD description (English source)

A vulnerability in the Contact Center Express (CCX) Editor application of Cisco Unified CCX could allow an unauthenticated, remote attacker to bypass authentication and obtain administrative permissions pertaining to script creation and execution. This vulnerability is due to improper authentication mechanisms in the communication between the CCX Editor and an affected Unified CCX server. An attacker could exploit this vulnerability by redirecting the authentication flow to a malicious server and tricking the CCX Editor into believing the authentication was successful. A successful exploit could allow the attacker to create and execute arbitrary scripts on the underlying operating system of an affected Unified CCX server, as an internal non-root user account.
