CVE-2025-68164Network attack vector

Port enumeration via Perforce connection test

Published Dec 16, 2025 · Updated Dec 16, 2025

Information disclosure in JetBrains TeamCity before 2025.11 allows remote authenticated users to enumerate ports through a Perforce connection test. The test accepts a caller-supplied Perforce server address and port and exposes observable response differences that reveal destination-port reachability. High-privileged TeamCity access is required, and the disclosed impact is limited to learning network service reachability from the server's position.
