CVE-2025-34211 is a critical vulnerability affecting the Vasion Print Virtual Appliance Host (formerly PrinterLogic) in versions prior to 22.0.1049 and the associated application prior to 20.0.2786, including both Virtual Appliance (VA) and SaaS deployments. The vulnerability arises from the use of a hard-coded private SSL key and matching public certificate stored in cleartext within the appliance. This key is associated with the hostname `pl-local.com` and is used to terminate TLS connections on standard web ports 80 and 443. Because the private key is embedded and identical across all deployed appliances, any attacker who gains container-level access can extract this key. Possession of the private key enables the attacker to decrypt TLS traffic, conduct man-in-the-middle (MITM) attacks, and forge TLS certificates. This allows impersonation of the appliance’s web user interface, interception of sensitive credentials, and unrestricted access to services trusting the compromised certificate. The vulnerability is classified under CWE-321 (Use of Hard-coded Cryptographic Key), which is a serious cryptographic weakness. The CVSS 4.0 base score is 9.3 (critical), reflecting the network attack vector, low attack complexity, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability. The scope is high since the compromise of a single key affects all installations globally. No known exploits are currently reported in the wild, but the ease of key extraction and the severity of impact make this a high-risk vulnerability requiring immediate remediation. The lack of patch links suggests that fixes may be forthcoming or that users must upgrade to versions 22.0.1049 or later to mitigate the issue.

For European organizations using Vasion Print Virtual Appliance Host, this vulnerability poses a significant risk to the confidentiality and integrity of print management infrastructure. The ability to decrypt TLS traffic and impersonate the appliance’s web interface could lead to credential theft, unauthorized administrative access, and lateral movement within corporate networks. Given that print services often integrate with directory services and handle sensitive document workflows, exploitation could expose sensitive corporate data and disrupt business operations. The uniformity of the hard-coded key across all deployments means that a single compromise anywhere could jeopardize the security of all European installations, amplifying the risk. Additionally, interception of TLS traffic could facilitate espionage or data exfiltration, which is particularly concerning for organizations in regulated sectors such as finance, healthcare, and government. The critical severity and network-based exploitability make this vulnerability a high priority for incident response and risk management teams in Europe.

European organizations should immediately verify their use of Vasion Print Virtual Appliance Host and determine the version in deployment. Upgrading to version 22.0.1049 or later for the appliance and 20.0.2786 or later for the application is essential to eliminate the hard-coded key vulnerability. Until upgrades are applied, organizations should isolate the appliance within segmented network zones with strict access controls to limit container-level access. Monitoring and logging should be enhanced to detect unusual access patterns or attempts to read private key files. Employing network-level TLS inspection with trusted certificates can help detect MITM attempts. Organizations should also consider rotating any credentials or certificates that may have been exposed due to this vulnerability. Engaging with Vasion support for guidance on interim mitigations or patches is recommended. Finally, organizations should conduct security audits and penetration tests focused on container security and TLS implementation to identify any residual risks.
