CVE-2025-34205 identifies a critical security flaw in Vasion Print Virtual Appliance Host and Application versions prior to 22.0.843 and 20.0.1923 respectively. The vulnerability stems from dead or insecure PHP code residing in multiple Docker-hosted PHP containers. The primary issue is an unauthenticated script located at /var/www/app/resetroot.php, which when accessed, executes a SQL update that resets the MySQL root user’s password to the SHA-512 hash of the string 'password'. This effectively grants an attacker full administrative access to the database without any authentication or user interaction. Additionally, there is commented-out code in /var/www/app/lib/common/oses.php that unserializes session data using PHP’s unserialize function on attacker-controlled input. If this code were re-enabled or accessed through other means, it could lead to remote code execution (RCE) due to PHP object injection vulnerabilities. The combination of these issues allows an attacker to first gain database control and then potentially escalate privileges to execute arbitrary code on the host system, leading to full system compromise. The vulnerability affects both Virtual Appliance (VA) and SaaS deployments, increasing the attack surface. The CVSS 4.0 vector indicates network attack vector, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. Although no exploits are publicly known yet, the ease of exploitation and critical impact make this a severe threat. The vendor has assigned this vulnerability the identifier V-2023-003 and classified it under CWE-561 (Dead Code).

For European organizations, the impact of CVE-2025-34205 is significant. Organizations using Vasion Print Virtual Appliance Host or Application in their print management infrastructure risk unauthorized full database access and potential full system compromise. This can lead to data breaches involving sensitive print job data, user credentials, and internal network information. Compromise of the print server can also serve as a pivot point for lateral movement within corporate networks, increasing the risk of widespread disruption and data exfiltration. The vulnerability’s unauthenticated nature means attackers can exploit it remotely without prior access, increasing exposure. Critical sectors such as government, finance, healthcare, and manufacturing that rely on print management solutions are particularly vulnerable. Disruption of print services can impact business continuity, and unauthorized access to internal systems can lead to regulatory non-compliance under GDPR and other data protection laws. The lack of known exploits currently provides a small window for mitigation before active exploitation emerges.

European organizations should immediately verify their use of Vasion Print Virtual Appliance Host and Application versions and upgrade to versions 22.0.843 or later for the Virtual Appliance and 20.0.1923 or later for the Application as soon as patches become available. Until patches are released, organizations should restrict network access to the resetroot.php endpoint by implementing firewall rules or network segmentation to limit exposure to trusted administrative hosts only. Disable or remove the resetroot.php script entirely if feasible. Conduct code audits to ensure the commented-out unserialize code remains disabled and monitor for any unauthorized code changes. Employ web application firewalls (WAFs) with rules to detect and block attempts to access resetroot.php or exploit PHP deserialization patterns. Monitor logs for unusual access patterns to the print appliance and database authentication failures. Implement strong database user management policies, including changing default or weak passwords and restricting database root access. Finally, conduct penetration testing focused on print infrastructure to identify any residual vulnerabilities.
