CVE-2025-34206 is a critical security vulnerability identified in the Vasion Print Virtual Appliance Host and Application, including both Virtual Appliance (VA) and Software-as-a-Service (SaaS) deployments. The core issue is an incorrect permission assignment (CWE-732) on critical host configuration and secret files that are mounted under /var/www/efs_storage into multiple Docker containers. These files include sensitive artifacts such as secrets.env, GPG-encrypted blobs stored in .secrets directories, MySQL client keys, and application session files. Due to overly permissive filesystem permissions, any attacker who gains control over or can access any one of these containers can read or modify these sensitive files. This exposure enables several attack vectors: theft of credentials, remote code execution (RCE) by leveraging the Laravel APP_KEY, takeover of the Portainer container management interface, and ultimately full system compromise. The vulnerability affects all versions of the product, indicating a systemic design flaw. The CVSS 4.0 base score of 9.3 reflects the vulnerability's high exploitability (network attack vector, no privileges or user interaction required) and severe impact on confidentiality, integrity, and availability. No known exploits are currently reported in the wild, but the ease of exploitation and critical impact make it a high priority for remediation. The vulnerability stems from the practice of mounting host secret material into containers without adequate access controls, violating container isolation principles and exposing sensitive data across container boundaries. This flaw can be exploited remotely without authentication, increasing the risk profile for affected deployments.

For European organizations, the impact of CVE-2025-34206 is substantial. Organizations relying on Vasion Print Virtual Appliance Host for print management, particularly those using containerized deployments or SaaS versions, face risks of credential theft leading to lateral movement within networks. The ability to execute remote code via Laravel APP_KEY compromise can allow attackers to deploy malware, ransomware, or establish persistent backdoors. Portainer takeover further enables attackers to manipulate container orchestration and deployment, potentially affecting multiple services beyond the print infrastructure. This can lead to operational disruption, data breaches involving sensitive print jobs or user data, and compliance violations under GDPR due to unauthorized access to personal data. The vulnerability's network-exploitable nature means attackers can target exposed services remotely, increasing the attack surface. Critical sectors such as government, finance, healthcare, and manufacturing in Europe, which often use centralized print management solutions, are at heightened risk. The potential for full system compromise threatens business continuity and could result in significant financial and reputational damage.

To mitigate CVE-2025-34206, organizations should immediately audit and restrict filesystem permissions on the /var/www/efs_storage directory and its contents to ensure that only authorized containers and processes can access sensitive files. Implement strict container isolation policies, avoiding the sharing of host secret material across multiple containers. Employ secrets management solutions that do not rely on mounting host files directly into containers, such as using Docker secrets or dedicated vault services. Regularly update Vasion Print Virtual Appliance Host to any future patched versions once released by the vendor. Monitor container logs and network traffic for unusual access patterns or unauthorized attempts to read or modify secret files. Limit network exposure of container management interfaces like Portainer by enforcing network segmentation and access controls. Conduct penetration testing focused on container escape and secret access scenarios. Finally, establish incident response plans specific to container compromise to quickly contain and remediate any exploitation attempts.
