Cisco Disaster Recovery Framework Command Injection Vulnerability
Description

A vulnerability in the Disaster Recovery framework of Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P), and Cisco Unity Connection could allow an authenticated, remote attacker to perform certain administrative actions they should not be able to. This vulnerability is due to insufficient access control checks on the affected device. An attacker with read-only privileges could exploit this vulnerability by executing a specific vulnerable command on an affected device.
