description

Cisco Emergency Responder, Cisco Unified Communications Manager, Unified Communications Manager IM and Presence Service, and Cisco Unity Connection are affected by improper-authentication issues. The available advisory text does not specify the attacker impact or any preconditions required to exploit them.

Still under analysis: more detail becomes available as the pipeline runs.

mitigation

Apply the applicable Cisco software-hardening releases for each affected product. No fixed version is recorded in the provided package data; restrict access to management and communications services until updates can be deployed.
