CVE-2017-6791 is a denial-of-service vulnerability in the Trust Verification Service (TVS) of Cisco Unified Communications Manager, affecting specific versions including 10.0, 10.5, and 11.0. An unauthenticated, remote attacker can exploit this by sending malformed TLS traffic, causing the TVS to become unavailable until manually restarted. The vulnerability has a CVSSv3 score of 7.5 (High), indicating a network-based attack with low complexity and no user interaction required, leading to high availability impact. There is no impact on confidentiality or integrity. Despite its high severity, there is no evidence of active exploitation, no public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage, suggesting it is not widely targeted.
