CVE-2025-34199: Vasion Print (formerly PrinterLogic) Insecure SSL Verification Allows Man-in-the-Middle Attacks

Severity: high (CVSS 8.1 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.5% probability of exploitation in the next 30 days
Public exploit or detection template: yes
Published: 2025-09-19 · updated 2026-10-18
Weakness: CWE-295

Description

Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 22.0.1049 and Application versions prior to 20.0.2786 (VA and SaaS deployments) contain insecure defaults and code patterns that disable TLS/SSL certificate verification for communications to printers and internal microservices. In multiple places, the application sets libcurl/PHP transport options such that CURLOPT_SSL_VERIFYHOST and CURLOPT_SSL_VERIFYPEER are effectively disabled, and environment variables (for example API_*_VERIFYSSL=false) are used to turn off verification for gateway and microservice endpoints. As a result, the client accepts TLS connections without validating server certificates (and, in some cases, uses clear-text HTTP), permitting on-path attackers to perform man-in-the-middle (MitM) attacks. An attacker able to intercept network traffic between the product and printers or microservices can eavesdrop on and modify sensitive data (including print jobs, configuration, and authentication tokens), inject malicious payloads, or disrupt service. This vulnerability has been identified by the vendor as: V-2024-024 — Insecure Communication to Printers & Microservices.
