Internal service access via unchecked printer host
Published Mar 5, 2025 · Updated Nov 3, 2025
SSRF in Vasion Print Application before 20.0.2014 and Virtual Appliance Host before 22.0.862 allows remote attackers to reach internal services. PHP printer-management endpoints build cURL destinations from a stored printer host address without validating the resulting URL or restricting its destination. A malicious printer record must supply the host value, after which an unauthenticated request can make the server contact internal or cloud-metadata services and return some responses.
