CVE-2025-20158

Admin-authenticated information disclosure via crafted debug-shell command

Published Feb 19, 2025 · Updated Feb 19, 2025

Information disclosure in Cisco Session Initiation Protocol (SIP) Software 3.2(1) and earlier allows local users to read sensitive data. The debug shell insufficiently validates a crafted SSH client command before processing it through the CLI, exposing information from the underlying operating system. Exploitation requires valid administrative credentials and SSH access on the phone; SSH is disabled by default, and no write or service impact is reported.
