CVE-2021-1532Network attack vector

Arbitrary file reads via unvalidated xAPI paths

Published May 6, 2021 · Updated Nov 8, 2024

Path traversal in Cisco TelePresence CE and RoomOS Software allows remote authenticated users to read arbitrary device files through xAPI commands. The video endpoint API fails to validate pathname-bearing command arguments before resolving them against the underlying filesystem. A valid xAPI account and network access are required; affected releases precede CE 9.14.6, 9.15.3, or 10.3.1 and RoomOS April 2021 Drop.
