CVE-2025-34235: Vasion Print (formerly PrinterLogic) Weak SSL/TLS Certificate Validation RCE

Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 25.1.102 and Application prior to version 25.1.1413 (Windows client deployments) contain a registry key that can be enabled by administrators, causing the client to skip SSL/TLS certificate validation. An attacker who can intercept HTTPS traffic can then inject malicious driver DLLs, resulting in remote code execution with SYSTEM privileges; a local attacker can achieve local privilege escalation via a junction‑point DLL injection. This vulnerability has been confirmed to be remediated, but it is unclear as to when the patch was introduced.

Security readout for executives and security teams

Plain-English summary

This flaw can turn a printer-management client into a full system compromise path. If the certificate-validation bypass is enabled, an attacker able to intercept HTTPS traffic may cause malicious driver DLLs to run as SYSTEM. The issue is reported as remediated, but patch-introduction timing is unclear.

Executive priority

Treat this as urgent for organizations running affected Vasion Print Windows client deployments. The impact is full endpoint control, but real-world urgency depends on version, registry configuration, and network interception exposure.

Technical view

Vasion Print, formerly PrinterLogic, VA Host before 25.1.102 and Windows client Application before 25.1.1413 can skip SSL/TLS certificate validation via an administrator-enabled registry key. That can permit malicious driver DLL injection over intercepted HTTPS, causing RCE as SYSTEM. A local privilege-escalation path via junction-point DLL injection is also described.

Likely exposure

Most relevant exposure is Windows client deployments using Vasion Print/PrinterLogic with older VA Host or Application versions, especially where the certificate-validation bypass registry key was enabled for operations or troubleshooting.

Exploitation context

No active exploitation is stated in the provided sources, and the CVE is not marked KEV. Exploitation requires specific conditions: certificate validation must be bypassed and the attacker must intercept HTTPS traffic, or have local access for the LPE path.

Researcher notes

The strongest evidence is the CVE description, vendor bulletin references, and VulnCheck advisory. Evidence is incomplete on the exact patch-introduction date. Do not assume exploitation in the wild from the provided bundle.

Mitigation direction

  • Upgrade VA Host to 25.1.102 or later where applicable.
  • Upgrade Windows client Application to 25.1.1413 or later where applicable.
  • Ensure the certificate-validation bypass registry key is not enabled.
  • Review Vasion security bulletins for exact fixed-release guidance.
  • Limit opportunities to intercept client-to-appliance HTTPS traffic.
  • Investigate suspicious printer driver DLL changes on Windows clients.

Validation and detection

  • Inventory Vasion Print VA Host and Windows client Application versions.
  • Check whether any certificate-validation bypass registry key is enabled.
  • Confirm vendor advisory status for your deployed release line.
  • Review endpoint logs for unexpected driver DLL installation activity.
  • Verify clients reject invalid or untrusted TLS certificates.
  • Prioritize systems where print clients run with SYSTEM privileges.
