CVE-2025-27642 is a critical security vulnerability identified in Vasion Print (formerly PrinterLogic) versions prior to Virtual Appliance Host 22.0.933 Application 20.0.2368. The vulnerability, categorized under CWE-306 (Missing Authentication for Critical Function), allows unauthenticated attackers to edit driver packages within the print management system. This flaw means that an attacker with network access to the vulnerable appliance can modify or replace printer drivers without any authentication, potentially injecting malicious code or disrupting printing services. The CVSS v3.1 base score of 9.8 reflects the vulnerability's high severity, with attack vector network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). Such a vulnerability could be exploited to execute arbitrary code on the print server, escalate privileges, or cause denial of service, impacting the entire print infrastructure. Although no exploits have been reported in the wild yet, the vulnerability's characteristics make it a prime target for attackers. The lack of authentication on a critical function exposes organizations to significant risk, especially those using centralized print management appliances in enterprise environments.

For European organizations, the impact of CVE-2025-27642 is substantial. Many enterprises and public sector entities rely on centralized print management solutions like Vasion Print to control and secure printing workflows. Exploitation could lead to unauthorized code execution within corporate networks, data exfiltration via manipulated print jobs, or disruption of printing services critical for business operations. Confidential documents could be intercepted or altered, violating data protection regulations such as GDPR. The integrity of print drivers being compromised could serve as a foothold for lateral movement within networks, increasing the risk of broader cyberattacks. Critical infrastructure sectors, including government, healthcare, and finance, which often use managed print services, could face operational disruptions and reputational damage. The unauthenticated nature of the vulnerability means attackers do not need valid credentials, increasing the likelihood of exploitation if network access is available.

1. Immediately restrict network access to Vasion Print management interfaces to trusted administrative networks only, using firewalls and network segmentation. 2. Monitor network traffic for unusual activity related to print server communications and driver package modifications. 3. Implement strict access controls and logging on print management appliances to detect unauthorized changes. 4. Coordinate with Vasion Print vendors for timely release and deployment of patches or updates addressing this vulnerability. 5. Until patches are available, consider disabling remote driver package editing features or isolating print servers from untrusted networks. 6. Conduct regular security audits and vulnerability scans focusing on print infrastructure. 7. Educate IT staff about the risks of unauthenticated access to print management systems and enforce strong authentication where possible. 8. Employ endpoint protection solutions that can detect anomalous behavior related to print driver modifications.
