A vulnerability in Cisco Unified Communications Domain Manager could allow an unauthenticated, remote attacker to bypass security protection

A vulnerability in Cisco Unified Communications Domain Manager could allow an unauthenticated, remote attacker to bypass security protections, gain elevated privileges, and execute arbitrary code. The vulnerability is due to insecure key generation during application configuration. An attacker could exploit this vulnerability by using a known insecure key value to bypass security protections by sending arbitrary requests using the insecure key to a targeted application. An exploit could allow the attacker to execute arbitrary code. This vulnerability affects Cisco Unified Communications Domain Manager releases prior to 11.5(2). Cisco Bug IDs: CSCuv67964.
