Executive Summary

This vulnerability is a cross-site request forgery (CSRF) issue in the web-based management interface of Cisco Unified Communications Manager (Unified CM) Software and Cisco Unified CM Session Management Edition (SME) Software. It occurs because the interface lacks sufficient CSRF protections. An unauthenticated, remote attacker can exploit this by tricking a user into clicking a malicious link, which then allows the attacker to perform arbitrary actions with the same privileges as the affected user.

Impact Analysis

If exploited, this vulnerability could allow an attacker to perform unauthorized actions on the affected device with the privileges of the user who clicks the malicious link. Although the impact on confidentiality and availability is none, there is a low impact on integrity. This means an attacker could potentially alter settings or configurations via the management interface, which could disrupt normal operations or security settings. [1]

Detection Guidance

There are no specific detection commands or methods provided for this vulnerability. Since it is a CSRF vulnerability in the web-based management interface, detection would typically involve monitoring for suspicious user interactions or unauthorized actions, but no explicit detection commands are available.
