CVE-2025-27675 is a critical security vulnerability affecting Vasion Print (formerly PrinterLogic) versions prior to Virtual Appliance Host 22.0.843 and Application 20.0.1923. The vulnerability stems from a flawed OpenID implementation (referenced as V-2023-004) that improperly handles authentication tokens or identity assertions, allowing an unauthenticated attacker to bypass authentication controls. This vulnerability is categorized under CWE-200, indicating exposure of sensitive information. The CVSS 3.1 base score of 9.8 reflects its critical nature: it is remotely exploitable over the network (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and affects confidentiality, integrity, and availability (C:H/I:H/A:H). Exploiting this flaw could allow attackers to gain unauthorized access to the print management system, manipulate print jobs, steal sensitive documents, or disrupt printing services. The lack of available patches at the time of disclosure increases the urgency for mitigation. Vasion Print is widely used in enterprise environments for centralized print management, making this vulnerability particularly impactful. The vulnerability’s exploitation could serve as a foothold for lateral movement within networks, especially in environments where print servers have elevated privileges or access to sensitive data flows.

For European organizations, the impact of CVE-2025-27675 is substantial. Many enterprises and public sector entities rely on Vasion Print for managing print infrastructure, which often handles sensitive documents including personal data protected under GDPR. Exploitation could lead to unauthorized disclosure of confidential information, violating data protection regulations and resulting in legal and financial penalties. Integrity of print jobs could be compromised, leading to misinformation or operational disruption. Availability impacts could halt printing services critical for business continuity, especially in sectors like healthcare, finance, and government. Additionally, attackers leveraging this vulnerability could pivot to other internal systems, escalating the severity of breaches. The absence of known exploits currently provides a window for proactive defense, but the critical CVSS score demands immediate attention to prevent potential attacks.

1. Apply patches or updates from Vasion Print as soon as they become available, prioritizing Virtual Appliance Host 22.0.843 and Application 20.0.1923 or later versions that address the vulnerability. 2. Until patches are available, restrict network access to print management interfaces using firewalls or network segmentation to limit exposure. 3. Implement strict monitoring and logging of authentication attempts and print job activities to detect anomalous behavior indicative of exploitation attempts. 4. Review and harden OpenID Connect configurations, ensuring tokens and identity assertions are validated correctly and securely. 5. Employ multi-factor authentication (MFA) where possible to add an additional layer of security around print management access. 6. Conduct regular security assessments and penetration testing focused on print infrastructure. 7. Educate IT and security teams about this vulnerability to ensure rapid response and incident handling. 8. Consider isolating print servers from critical network segments to reduce potential lateral movement.
