CVE-2025-14013 is a cross-site scripting vulnerability identified in JIZHICMS, a content management system, affecting versions 2.5.0 through 2.5.5. The vulnerability resides in the Comment Handler component, specifically within the /index.php/admins/Comment/addcomment.html endpoint. The issue arises from improper input validation and sanitization of the 'body' parameter, which is used to submit comments. An attacker with high privileges can craft malicious input that injects executable scripts into the web interface. When other users or administrators view the affected comment, the injected script executes in their browsers, potentially leading to session hijacking, credential theft, or unauthorized actions within the CMS. The attack vector is remote and requires user interaction, as the victim must load the malicious comment. The CVSS 4.0 vector indicates no authentication is bypassed, but privileges are required (PR:H), and user interaction is necessary (UI:P). The vendor has not issued a patch or responded to the vulnerability disclosure, and while a public exploit exists, no active exploitation has been observed in the wild. This vulnerability is particularly concerning for organizations relying on JIZHICMS for administrative content management, as it compromises the integrity and confidentiality of administrative sessions and data.

For European organizations, this vulnerability poses a risk primarily to those using JIZHICMS for website or content management, especially where administrative users have the ability to add comments. Successful exploitation can lead to session hijacking, allowing attackers to impersonate administrators and potentially modify or delete content, inject further malicious code, or access sensitive information. This undermines the integrity and confidentiality of the affected systems. Although the vulnerability does not directly impact availability, the reputational damage from defacement or data leakage can be significant. Given the requirement for high privileges and user interaction, the attack surface is somewhat limited, but insider threats or compromised administrator accounts could facilitate exploitation. The lack of vendor response and patches increases the risk exposure duration. European organizations in sectors such as government, education, and media that rely on JIZHICMS may face targeted attacks aiming to disrupt services or steal sensitive data.

1. Restrict administrative access to the Comment Handler component by implementing strict access controls and network segmentation to limit exposure. 2. Deploy a web application firewall (WAF) with robust XSS detection and filtering rules to block malicious payloads targeting the 'body' parameter. 3. Conduct regular input validation and sanitization audits on all user-supplied data, especially in comment submission forms. 4. Monitor logs for unusual comment submissions or script injections and establish alerting mechanisms for suspicious activities. 5. Educate administrators about the risks of clicking on untrusted links or viewing unverified comments. 6. If possible, disable or limit the comment functionality until a vendor patch or official fix is released. 7. Consider migrating to alternative CMS platforms with active security support if JIZHICMS remains unpatched. 8. Implement Content Security Policy (CSP) headers to reduce the impact of XSS attacks by restricting script execution sources.
