CVE-2025-27647 is a critical security vulnerability affecting Vasion Print (formerly PrinterLogic) software versions prior to Virtual Appliance Host 22.0.913 Application 20.0.2253. The vulnerability, classified under CWE-306 (Missing Authentication for Critical Function), allows an unauthenticated attacker to add partial administrative users to the system. This means an attacker can create accounts with elevated privileges without any authentication or user interaction, remotely over the network. The CVSS v3.1 score of 9.8 reflects the high severity, with attack vector being network-based (AV:N), no required privileges (PR:N), no user interaction (UI:N), and full impact on confidentiality, integrity, and availability (C:H/I:H/A:H). The flaw essentially bypasses authentication controls, enabling attackers to gain administrative access to the print management system. This can lead to unauthorized control over printing infrastructure, data leakage, manipulation or deletion of print jobs, and potential pivoting to other network resources. No patches or exploit code are currently publicly available, but the vulnerability is already published and should be treated as critical. Organizations relying on Vasion Print for centralized print management must urgently assess their exposure and prepare for remediation.

For European organizations, the impact of CVE-2025-27647 is significant. Unauthorized addition of admin users can lead to full compromise of print management infrastructure, which is often integrated with broader IT systems. This can result in data breaches involving sensitive documents, disruption of business operations due to denial of printing services, and potential lateral movement within corporate networks. Critical sectors such as government, finance, healthcare, and manufacturing that depend on secure and reliable printing services are particularly vulnerable. The loss of confidentiality, integrity, and availability can damage organizational reputation, lead to regulatory penalties under GDPR, and cause operational downtime. Given the network-exploitable nature and lack of authentication requirement, the vulnerability can be exploited by remote attackers without prior access, increasing the risk of widespread attacks across European enterprises.

1. Immediate application of vendor patches or updates once they become available is paramount. Monitor Vasion Print vendor communications for security advisories. 2. Until patches are released, restrict network access to the Vasion Print management interfaces using firewalls and network segmentation to limit exposure to trusted administrators only. 3. Implement strict monitoring and alerting for any new user account creations or privilege escalations within the print management system. 4. Conduct regular audits of user accounts and permissions to detect unauthorized additions. 5. Employ multi-factor authentication (MFA) for administrative access where supported to add an additional security layer. 6. Consider deploying intrusion detection/prevention systems (IDS/IPS) to identify anomalous activities related to print server access. 7. Educate IT and security teams about the vulnerability to ensure rapid incident response if exploitation attempts are detected. 8. Review and harden overall print infrastructure security posture, including limiting administrative privileges to the minimum necessary.
