What is CVE-2025-34215?

The Vasion Print Virtual Appliance and Application have a serious vulnerability that allows unauthenticated access to a firmware-upload functionality. Prior versions of these products expose a public endpoint that generates a signed token for firmware uploading. This mechanism is flawed, as every Docker image includes the appliance's private GPG key and a hard-coded passphrase. An attacker who can extract this key and obtain a valid token can manipulate firmware, leading to remote code execution and potential system compromise.
