CVE-2025-27637 identifies a Cross-Site Scripting (XSS) vulnerability in Vasion Print (formerly PrinterLogic) products prior to Virtual Appliance Host version 22.0.1002 and Application version 20.0.2614. XSS vulnerabilities, classified under CWE-79, occur when an application includes untrusted user input in web pages without proper validation or encoding, allowing attackers to inject malicious scripts. This particular vulnerability is remotely exploitable over the network without requiring authentication (AV:N/PR:N), but it requires user interaction (UI:R) such as clicking a crafted link or visiting a malicious page. The vulnerability impacts confidentiality and integrity (C:L/I:L) but does not affect availability (A:N). The scope is changed (S:C), indicating that exploitation could affect resources beyond the vulnerable component, such as user sessions or other users. The CVSS 3.1 base score is 6.1, reflecting medium severity. No public exploits or active exploitation in the wild have been reported as of the publication date (March 5, 2025). The vulnerability likely arises from insufficient input sanitization or output encoding in the web interface of the print management system, enabling script injection. Attackers could leverage this to steal session cookies, perform actions on behalf of users, or manipulate displayed content, potentially leading to further attacks or data exposure. Given the nature of print management systems, which often integrate with enterprise networks and user authentication, this vulnerability could be leveraged as a foothold or pivot point in targeted attacks.

For European organizations, the impact of CVE-2025-27637 centers on the risk of unauthorized script execution within the context of the Vasion Print web application. This can lead to session hijacking, credential theft, or unauthorized actions performed with the privileges of legitimate users, compromising confidentiality and integrity of sensitive print job data or administrative functions. While availability is not directly affected, the breach of trust and potential lateral movement within networks can have broader security implications. Organizations relying on Vasion Print for centralized print management, especially those handling sensitive documents or operating in regulated sectors (e.g., finance, healthcare, government), face increased risk of data leakage or compliance violations. The requirement for user interaction means social engineering or phishing tactics could be used to trigger exploitation, increasing the threat to end users. Additionally, the vulnerability's presence in virtual appliance hosts suggests that cloud or virtualized deployments are also at risk, potentially affecting multi-tenant environments or remote offices. Without timely patching or mitigation, attackers could exploit this vulnerability to gain unauthorized access or disrupt secure printing workflows, undermining operational security.

To mitigate CVE-2025-27637, European organizations should: 1) Monitor vendor communications closely and apply official patches or updates for Vasion Print Virtual Appliance Host and Application as soon as they become available. 2) Implement strict input validation and output encoding on all user-supplied data within the print management web interface to prevent script injection. 3) Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce XSS attack surface. 4) Educate users about the risks of clicking on suspicious links or interacting with untrusted content related to print management portals. 5) Conduct regular security assessments and penetration testing focused on web application vulnerabilities in print infrastructure. 6) Segment print management systems from critical network assets to limit potential lateral movement in case of compromise. 7) Enable multi-factor authentication (MFA) for administrative access to the print management system to reduce risk from stolen credentials. 8) Monitor logs and network traffic for unusual activities indicative of exploitation attempts. These targeted measures go beyond generic advice by addressing the specific attack vectors and operational context of Vasion Print deployments.
