CVE-2025-63911Public exploitNetwork attack vector

Authenticated shell escape via unsanitized CLISH parameters

Published Mar 3, 2026 · Updated Mar 3, 2026

Command injection in Cohesity TranZman Migration Appliance 4.0 Build 14614 allows remote authenticated users to gain shell access. CLISH passes STRING parameters from the personality and load_media commands into privileged shell actions, while its deny-hyphen pattern accepts shell metacharacters. An admin login and CLISH enable mode are required; injected separators escape the restricted shell as the unconfined admin user.
