CVE-2025-63910Public exploitNetwork attack vector

Root code execution via unsigned patch upload

Published Mar 3, 2026 · Updated Mar 3, 2026

Arbitrary file upload in Cohesity TranZman Migration Appliance 4.0 Build 14614 allows remote authenticated users to execute code as root. The Flask patch routes in /opt/SRLtzm/web/tranzman/views/patch.py decrypt, install, and execute uploaded patches with a shared static key but no signature, source, or content validation. Administrator access and possession of the shared key are required to re-encrypt a modified vendor patch; applying the patch grants full control of the appliance.
