CVE-2025-27654 is a Cross Site Scripting (XSS) vulnerability identified in Vasion Print (formerly known as PrinterLogic) versions prior to Virtual Appliance Host 22.0.862 Application 20.0.2014. XSS vulnerabilities, classified under CWE-79, occur when an application does not properly sanitize user-supplied input, allowing attackers to inject malicious scripts into web pages viewed by other users. In this case, the vulnerability enables an attacker to execute arbitrary scripts in the context of the affected web application. The CVSS v3.1 base score is 6.1, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) reveals that the vulnerability can be exploited remotely over the network without requiring privileges, but it does require user interaction (such as clicking a crafted link). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality and integrity to a limited extent (C:L/I:L), but does not affect availability. No known exploits are currently reported in the wild, and no patches or vendor advisories have been linked yet. The vulnerability is relevant to organizations using Vasion Print's virtual appliance hosting software, which is typically deployed in enterprise environments to manage print services centrally via web interfaces.

For European organizations, the impact of this XSS vulnerability primarily concerns the risk of session hijacking, credential theft, or unauthorized actions performed in the context of authenticated users accessing the Vasion Print management interface. Since print management systems often integrate with enterprise identity and access management, exploitation could lead to lateral movement or data exposure within corporate networks. Confidentiality and integrity impacts, while limited, can still facilitate further attacks or data leakage. The requirement for user interaction reduces the likelihood of automated widespread exploitation but does not eliminate targeted phishing or social engineering risks. Organizations relying heavily on Vasion Print for centralized print infrastructure management, especially those with sensitive or regulated data, could face compliance and operational risks if attackers leverage this vulnerability to compromise administrative sessions or inject malicious content. The absence of known exploits suggests a window of opportunity for proactive mitigation before active attacks emerge.

Beyond generic advice, European organizations should: 1) Immediately audit and inventory all deployments of Vasion Print virtual appliance hosts to identify affected versions. 2) Implement strict input validation and output encoding on all user-supplied data fields within the print management interface, if customizations are possible. 3) Enforce multi-factor authentication (MFA) for all administrative access to reduce the risk of session hijacking. 4) Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the web application context. 5) Educate users and administrators about phishing risks and the dangers of clicking unsolicited links related to print management portals. 6) Monitor web server logs and network traffic for suspicious requests that may indicate attempted exploitation of XSS vectors. 7) Engage with Vasion Print vendor support channels to obtain patches or updates as soon as they become available and plan timely patch deployment. 8) Consider network segmentation of print management infrastructure to limit exposure and potential lateral movement in case of compromise.
