description

Cisco TelePresence VCS Expressway devices are affected by an issue in the database service that can allow remote operating-system command execution as root. An attacker needs network access to the device and possession of persistent cookies; clustered deployments using TLS Verify Mode enabled are implicated by the certificate-validation condition.

mitigation

Restrict database-service network access to trusted cluster peers and other required management hosts, and rotate or invalidate persistent cookies where operationally possible. Review clustered TLS client-certificate validation and apply Cisco updates when a fixed release is provided.
