CVE-2025-27646 is a critical security vulnerability identified in Vasion Print (formerly known as PrinterLogic) versions prior to Virtual Appliance Host 22.0.913 Application 20.0.2253. The vulnerability is classified under CWE-284, which relates to improper access control. Specifically, it allows an attacker to edit user accounts without requiring any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). This means the vulnerability can be exploited remotely over the network with low attack complexity and no privileges or user involvement. The impact is severe, affecting confidentiality, integrity, and availability (all rated high), potentially allowing attackers to gain unauthorized administrative control over the print management system. Such control could enable attackers to manipulate print jobs, access sensitive documents, or pivot to other network resources. Although no public exploits are currently known, the high CVSS score of 9.8 reflects the critical nature of this flaw. The vulnerability arises from insufficient access control mechanisms in the user account management functionality of the Vasion Print virtual appliance. Given the central role of print management in many enterprise environments, exploitation could disrupt business operations and lead to data breaches. The vulnerability was published on March 5, 2025, and no patches or mitigations are explicitly listed in the provided data, emphasizing the need for immediate attention from affected organizations.

For European organizations, the impact of CVE-2025-27646 could be substantial. Many enterprises, government agencies, and healthcare providers rely on centralized print management solutions like Vasion Print to handle large volumes of sensitive documents. Exploitation could lead to unauthorized modification or deletion of user accounts, enabling attackers to gain administrative privileges within the print management system. This could result in interception or manipulation of confidential print jobs, disruption of printing services critical to business operations, and potential lateral movement within internal networks. The compromise of integrity and availability of print services could affect operational continuity, especially in sectors where printed documentation is essential for compliance or legal purposes. Additionally, attackers leveraging this vulnerability might use the compromised print infrastructure as a foothold to escalate privileges or exfiltrate sensitive data. The lack of required authentication and user interaction lowers the barrier for attackers, increasing the likelihood of exploitation if the vulnerability is not addressed promptly.

Given the critical nature of CVE-2025-27646 and the absence of publicly available patches, European organizations should implement immediate compensating controls. These include: 1) Restricting network access to the Vasion Print management interfaces by implementing strict firewall rules and network segmentation to limit exposure to trusted administrative hosts only. 2) Enforcing strong access control policies and monitoring for any unauthorized changes to user accounts within the print management system. 3) Deploying intrusion detection or prevention systems (IDS/IPS) to detect anomalous activities related to user account modifications. 4) Reviewing and hardening the configuration of the print management appliance, disabling any unnecessary services or interfaces that could be exploited. 5) Engaging with Vasion Print support or vendors to obtain any available patches or updates as soon as they are released. 6) Conducting regular audits and penetration testing focused on print infrastructure to identify and remediate potential weaknesses. 7) Educating IT and security teams about this vulnerability to ensure rapid response and mitigation efforts. These measures will help reduce the attack surface and limit the potential impact until an official patch is available.
