CVE-2025-14801 is a cross-site scripting vulnerability identified in the xiweicheng TMS product, affecting all versions up to 2.28.0. The vulnerability resides in the createComment function of the /admin/blog/comment/create endpoint, where the content argument is improperly sanitized, allowing attackers to inject malicious JavaScript code. This flaw can be exploited remotely by an attacker with high privileges who can interact with the system, typically an authenticated administrator or user with comment creation rights. The vulnerability does not require authentication bypass but does require user interaction, such as an administrator viewing or interacting with the injected comment. The CVSS 4.0 base score is 4.8 (medium severity), reflecting the limited scope and required conditions for exploitation. The vendor was notified early but has not issued any patches or advisories, and no known exploits have been detected in the wild to date. The vulnerability could enable attackers to execute arbitrary scripts in the context of the administrative interface, potentially leading to session hijacking, unauthorized actions, or phishing attacks targeting administrators. Given the administrative nature of the affected endpoint, the impact on confidentiality and integrity is moderate, while availability impact is minimal. The vulnerability affects a broad range of versions, indicating a long-standing issue in the product's comment handling functionality.

For European organizations using xiweicheng TMS, this vulnerability poses a moderate risk primarily to administrative users who have the ability to create comments via the vulnerable endpoint. Successful exploitation could lead to session hijacking, unauthorized administrative actions, or the injection of malicious content that could deceive administrators or other users. This could result in data integrity issues, unauthorized changes to the system, or further compromise of internal networks. Although the vulnerability does not directly impact availability, the potential for privilege escalation or lateral movement within the network increases the overall risk profile. Organizations in sectors with high reliance on web-based content management and administrative interfaces, such as government, finance, and critical infrastructure, may face increased risk due to the potential for targeted attacks. The lack of vendor response and patches increases exposure time, necessitating proactive mitigation. Additionally, the public disclosure of the exploit details raises the likelihood of opportunistic attacks, especially in environments where administrative access controls are weak or where user interaction can be socially engineered.

1. Implement strict input validation and output encoding on the content parameter in the createComment function to neutralize malicious scripts. 2. Apply web application firewalls (WAFs) with rules targeting known XSS payloads to block exploitation attempts at the network perimeter. 3. Restrict access to the /admin/blog/comment/create endpoint to trusted IP addresses or VPN-only access to reduce exposure. 4. Enforce multi-factor authentication (MFA) for all administrative users to mitigate the impact of session hijacking. 5. Conduct regular security audits and code reviews focusing on input handling in administrative modules. 6. Monitor logs for unusual comment creation activity or script injection attempts. 7. Educate administrators about the risks of interacting with untrusted content and encourage cautious behavior. 8. If possible, isolate the TMS administrative interface from general user networks to limit lateral movement. 9. Engage with the vendor or community to track patch developments and apply updates promptly once available. 10. Consider deploying Content Security Policy (CSP) headers to restrict script execution sources within the administrative interface.
