Detailsinfo

A vulnerability classified as problematic was found in Vasion Print Virtual Appliance Host and Print Application. This vulnerability affects some unknown processing of the component Environment Variable Handler. The manipulation with an unknown input leads to a cleartext transmission vulnerability. The CWE definition for the vulnerability is CWE-319. The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors. As an impact it is known to affect confidentiality. CVE summarizes:

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.

The weakness was disclosed by Pierre Barre. The advisory is shared for download at help.printerlogic.com. This vulnerability was named CVE-2025-34199 since 04/15/2025. The exploitation appears to be difficult. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1040.

Upgrading to version 22.0.1049 eliminates this vulnerability.
