CVE-2025-14801 is a cross-site scripting vulnerability affecting the xiweicheng TMS product up to version 2.28.0. The flaw resides in the createComment function located at /admin/blog/comment/create, where the content argument is improperly sanitized, allowing injection of malicious JavaScript code. An attacker with high privileges on the system can remotely exploit this vulnerability by submitting crafted input that executes in the context of an administrative user’s browser session. The vulnerability requires user interaction, such as an admin viewing a malicious comment, to trigger the script execution. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required (though the vector states PR:H, meaning high privileges are needed), user interaction required, and limited impact on integrity and no impact on confidentiality or availability. The vendor has been notified but has not issued any patches or responses, and no known exploits are currently active in the wild, though exploit details have been publicly disclosed. This vulnerability could be leveraged to perform session hijacking, steal credentials, or conduct unauthorized administrative actions by executing scripts in the context of the admin interface. The lack of vendor response and patch availability increases the risk for organizations relying on this software.

For European organizations using xiweicheng TMS, this vulnerability poses a risk primarily to administrative users who manage content via the vulnerable comment creation function. Successful exploitation could lead to compromise of admin sessions, unauthorized changes to content or configurations, and potential lateral movement within the network. This could disrupt business operations, damage reputations, and lead to data breaches. The impact is heightened in sectors with critical content management needs such as government, media, and large enterprises. Since the vulnerability requires high privileges and user interaction, the attack surface is somewhat limited but still significant, especially if attackers gain initial access through other means. The absence of vendor patches means organizations must rely on internal mitigations, increasing operational overhead and risk. European entities with regulatory obligations around data protection (e.g., GDPR) may face compliance risks if exploitation leads to data exposure.

Given the lack of vendor patches, European organizations should implement immediate compensating controls. These include: 1) Restricting access to the /admin/blog/comment/create endpoint to trusted IP addresses or VPN users only. 2) Implementing web application firewalls (WAFs) with custom rules to detect and block suspicious input patterns targeting the content parameter. 3) Enforcing strict input validation and output encoding on the server side where possible, potentially via custom middleware or reverse proxies. 4) Conducting regular monitoring and logging of admin interface activities to detect anomalous behavior. 5) Educating administrative users about the risks of interacting with untrusted content and encouraging cautious behavior. 6) Segregating administrative interfaces from general user access networks to reduce exposure. 7) Planning for migration or upgrade to alternative TMS solutions if vendor support remains absent. These steps go beyond generic advice by focusing on access control, detection, and operational practices tailored to this vulnerability’s characteristics.
