CVE-2025-34217
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVasion Print (formerly PrinterLogic) Virtual Appliance Host and Application (VA/SaaS deployments) contain an undocumented 'printerlogic' user with a hardcoded SSH public key in '~/.ssh/authorized_keys' and a sudoers rule granting the printerlogic_ssh group 'NOPASSWD: ALL'. Possession of the matching private key gives an attacker root access to the appliance.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceVasion Print Virtual Appliance contains an undocumented 'printerlogic' user with a hardcoded SSH public key in the authorized_keys file. A corresponding sudoers rule grants the printerlogic_ssh group NOPASSWD: ALL privileges, allowing anyone with the matching private key to gain root access to the appliance.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify if the printerlogic user existsRun 'id printerlogic' or 'getent passwd printerlogic' to check if the user account is present on the systemAffected if The printerlogic user account exists on the system
-
Check if printerlogic belongs to printerlogic_ssh groupRun 'id printerlogic' or 'groups printerlogic' to list all groups the user belongs toAffected if The printerlogic user is a member of the printerlogic_ssh group
-
Inspect sudoers for printerlogic NOPASSWD privilegesCheck /etc/sudoers or /etc/sudoers.d/ for entries containing 'printerlogic' and 'NOPASSWD:ALL'. Use 'sudo grep -r printerlogic /etc/sudoers.d/' or 'sudo visudo' to reviewAffected if A sudoers rule grants printerlogic user NOPASSWD:ALL privileges without requiring a password
-
Review printerlogic user's SSH authorized_keysExamine ~/.ssh/authorized_keys for the printerlogic user home directory (typically /home/printerlogic/.ssh/authorized_keys or /root/.ssh/authorized_keys if printerlogic has root access)Affected if The authorized_keys file contains a public key for the printerlogic user
-
Confirm SSH service accessibilityCheck if SSH is running: 'systemctl status sshd' or 'systemctl status ssh'. Verify SSH port 22 is listening: 'netstat -tlnp | grep :22' or 'ss -tlnp | grep :22'Affected if SSH daemon is running and accepting connections, allowing the hardcoded key to be used for authentication
The environment is affected if the printerlogic user exists, belongs to printerlogic_ssh group, has NOPASSWD:ALL sudo privileges, and SSH is accessible - all of which enable unauthenticated root access via the hardcoded SSH key.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImmediately disable or remove the undocumented printerlogic user and its associated SSH key, audit and restrict the sudoers configuration to remove NOPASSWD: ALL rules, and rotate all credentials across the appliance.
