CVE-2020-3135

A vulnerability in the web-based management interface of Cisco Unified Communications Manager (UCM) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected device. The vulnerability is due to insufficient CSRF protections for the web-based management interface on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the targeted user.
