CVE-2025-27673Network attack vector

Session compromise via cookies returned in response bodies

Published Mar 5, 2025 · Updated Mar 5, 2025

Persistent-cookie disclosure in Vasion Print before Application 20.0.1923 and Virtual Appliance Host 22.0.843 exposes cookies to remote attackers. HTTP response generation incorrectly places persistent cookie data in the response body; public records do not identify the responsible endpoint or code. No authentication or user interaction is required, and exposed authentication material permits session impersonation, although the session privilege is undisclosed.
