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 · unedited
Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 22.0.843 and Application prior to 20.0.1923 (VA and SaaS deployments) contains dangerous PHP dead code present in multiple Docker-hosted PHP instances. A script named /var/www/app/resetroot.php (found in several containers) lacks authentication checks and, when executed, performs a SQL update that sets the database administrator username to 'root' and its password hash to the SHA-512 hash of the string 'password'. Separately, commented-out code in /var/www/app/lib/common/oses.php would unserialize session data (unserialize($_SESSION['osdata']))—a pattern that can enable remote code execution if re-enabled or reached with attacker-controlled serialized data. An attacker able to reach the resetroot.php endpoint can trivially reset the MySQL root password and obtain full database control; combined with deserialization issues this can lead to full remote code execution and system compromise. This vulnerability has been identified by the vendor as: V-2023-003 — Dead / Insecure PHP Code.

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 confidence

The Vasion Print Virtual Appliance and Application contain dangerous PHP code allowing unauthenticated database root password reset via /var/www/app/resetroot.php, which executes a SQL update setting credentials to 'root'/'password' (SHA-512). Additionally, commented-out deserialization code in /var/www/app/lib/common/oses.php using unserialize($_SESSION['osdata']) can enable RCE if reached with attacker-controlled serialized data. This affects VA versions prior to 22.0.843 and Application versions prior to 20.0.1923.

MitigationImmediately upgrade Virtual Appliance to version 22.0.843+ and Application to 20.0.1923+ per vendor guidance. Restrict network access to PHP endpoints and rotate any exposed credentials immediately, as the resetroot.php vulnerability allows trivial administrative database access.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Virtual Appliance Application version
    Locate the installed Vasion Application version number in the web interface (typically under Help > About or System Info) or check version files in the appliance filesystem
    Affected if Version is below 20.0.1923
  2. Check Virtual Appliance Host version
    Locate the installed Vasion Host version number in the web interface or check version files in the appliance filesystem
    Affected if Version is below 22.0.843
  3. Verify presence of vulnerable resetroot.php
    Inspect the file /var/www/app/resetroot.php on the appliance. If it exists and contains SQL UPDATE logic that sets root credentials to 'root'/'password', the vulnerability is present
    Affected if File exists and contains the password reset logic
  4. Check for deserialization code in oses.php
    Inspect /var/www/app/lib/common/oses.php for commented-out or active unserialize($_SESSION['osdata']) calls
    Affected if unserialize() calls using session data are present or were recently present in the code

Environment is affected if either Application version is below 20.0.1923 or Host version is below 22.0.843, AND the vulnerable PHP files with password reset or deserialization code are present on the system

Interim mitigation

Immediately upgrade Virtual Appliance to version 22.0.843+ and Application to 20.0.1923+ per vendor guidance. Restrict network access to PHP endpoints and rotate any exposed credentials immediately, as the resetroot.php vulnerability allows trivial administrative database access.

Recommended fix High confidence

Virtual Appliance Application 20.0.1923 and Virtual Appliance Host 22.0.843

  1. Verify current Virtual Appliance Application and Host versions via the admin console or CLI
  2. Download Virtual Appliance Application version 20.0.1923 or later from the vendor portal
  3. Download Virtual Appliance Host version 22.0.843 or later from the vendor portal
  4. Schedule a maintenance window following backup procedures
  5. Apply the Virtual Appliance Host upgrade first (22.0.843 or later)
  6. Apply the Virtual Appliance Application upgrade second (20.0.1923 or later)
  7. Verify the /var/www/app/resetroot.php file has been removed or secured in updated versions
  8. Confirm all services are operational post-upgrade
Caveat Review vendor release notes for migration considerations before upgrading
