TITLE

Cisco Unified Communications Manager  Cross Site Request Forgery Vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2020-011573

DESCRIPTION

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. Cisco Unified Communications Manager (CUCM, Unified CM, CallManager) is a call processing component in a unified communication system of Cisco (Cisco). This component provides a scalable, distributed and highly available enterprise IP telephony call processing solution. The vulnerability stems from the WEB application not adequately verifying that the request is from a trusted user
