CVE-2025-27637 is a Cross-Site Scripting (XSS) vulnerability identified in Vasion Print (formerly known as PrinterLogic) versions prior to Virtual Appliance Host 22.0.1002 Application 20.0.2614. The vulnerability is classified under CWE-79, which involves improper neutralization of input leading to the execution of malicious scripts in the context of a victim's browser. This flaw allows an attacker to inject malicious scripts that execute when a user interacts with the vulnerable web interface, potentially leading to the theft of session tokens, user impersonation, or manipulation of web content. The CVSS v3.1 base score is 6.1, indicating a medium severity level. The vector details specify that the attack can be launched remotely over the network (AV:N) with low attack complexity (AC:L), requires no privileges (PR:N), but does require user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality and integrity is low (C:L, I:L), with no impact on availability (A:N). There are no known exploits in the wild at the time of publication, and no patches or vendor advisories have been linked yet. The vulnerability affects web-based management interfaces of the Vasion Print appliance, which is used for centralized print management in enterprise environments. Given the nature of XSS, exploitation typically requires a user to visit a crafted URL or interact with malicious content, which then executes script code in their browser session within the context of the vulnerable application.

For European organizations, the impact of this vulnerability can be significant in environments where Vasion Print is deployed to manage print services across corporate networks. Successful exploitation could lead to session hijacking, unauthorized actions performed on behalf of legitimate users, or the exposure of sensitive information accessible through the print management interface. This could compromise the integrity of print job management, potentially leading to unauthorized document access or manipulation. While the vulnerability does not directly affect system availability, the confidentiality and integrity impacts could facilitate further attacks or data leakage. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, may face compliance risks if sensitive information is exposed. Additionally, since print management systems often integrate with directory services and internal networks, an attacker leveraging this XSS could pivot to more critical systems if combined with other vulnerabilities or misconfigurations.

Given the absence of official patches at the time of reporting, European organizations should implement several targeted mitigations: 1) Restrict access to the Vasion Print management interface to trusted networks and users only, ideally via VPN or secure internal networks, to reduce exposure to external attackers. 2) Employ web application firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting the print management interface. 3) Educate users with access to the interface about the risks of clicking on untrusted links or opening suspicious emails, as user interaction is required for exploitation. 4) Monitor logs for unusual or suspicious requests that may indicate attempted exploitation. 5) Once available, promptly apply vendor patches or updates to remediate the vulnerability. 6) Consider implementing Content Security Policy (CSP) headers on the appliance’s web interface to limit the execution of unauthorized scripts. 7) Conduct regular security assessments and penetration tests focused on web interfaces to identify and remediate similar vulnerabilities proactively.
