CVE-2025-27681 is a critical security vulnerability identified in Vasion Print (formerly PrinterLogic) versions prior to Virtual Appliance Host 1.0.735 Application 20.0.1330. The vulnerability stems from improper handling of client inter-process security mechanisms, classified under CWE-602, which relates to insufficient validation of inter-process communication (IPC) permissions. This flaw allows an unauthenticated attacker to remotely exploit the vulnerability over the network without any user interaction, leading to full compromise of confidentiality, integrity, and availability of the affected system. The CVSS v3.1 base score of 9.8 reflects the severity, indicating that the attack vector is network-based (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and impacts all three security properties (C:H/I:H/A:H). Although no public exploits have been reported yet, the nature of the vulnerability suggests that exploitation could allow arbitrary code execution or unauthorized access to sensitive print management functions, potentially disrupting print services or enabling lateral movement within enterprise networks. The vulnerability affects print management infrastructure, which is often integrated into enterprise IT environments, making it a high-value target for attackers seeking to disrupt operations or exfiltrate data.

For European organizations, the impact of CVE-2025-27681 is significant due to the critical role print management systems play in daily operations across various sectors, including government, finance, healthcare, and manufacturing. Exploitation could lead to unauthorized access to sensitive documents, disruption of printing services, and potential footholds for further network compromise. Confidentiality breaches could expose sensitive or personal data protected under GDPR, leading to regulatory penalties and reputational damage. Integrity and availability impacts could disrupt business continuity, causing operational delays and financial losses. The network-based, unauthenticated nature of the vulnerability increases the risk of widespread exploitation, especially in organizations with exposed or poorly segmented print management infrastructure. Given the critical severity, organizations must treat this vulnerability as a high-priority risk to their cybersecurity posture.

1. Immediately upgrade Vasion Print to Virtual Appliance Host 1.0.735 Application 20.0.1330 or later, where the vulnerability is addressed. 2. If patching is not immediately possible, restrict network access to print management interfaces using firewalls or network segmentation to limit exposure to trusted hosts only. 3. Implement strict access controls and monitoring on inter-process communication channels related to print services to detect and prevent unauthorized interactions. 4. Employ network intrusion detection systems (IDS) and endpoint detection and response (EDR) tools to identify anomalous activities indicative of exploitation attempts. 5. Conduct regular audits of print management configurations and logs to identify suspicious behavior. 6. Educate IT staff about the vulnerability and ensure incident response plans include scenarios involving print infrastructure compromise. 7. Coordinate with vendors for timely updates and security advisories to stay informed about any emerging exploits or patches.
