CVE-2025-27680Public exploitNetwork attack vector

Appliance compromise via exposed firmware-signing key

Published Mar 5, 2025 · Updated Nov 3, 2025

Firmware verification in Vasion Print Virtual Appliance Host before 1.0.750 and Application before 20.0.1442 lets attackers compromise appliances. The unauthenticated /va-api update route accepts signatures derived from MS_AUTH_KEY, while that key is stored in appliance.env and exposed to numerous appliance containers. Access to the key through that file or an affected container enables a malicious image to be uploaded and installed without administrator credentials.
