CVE-2025-14005 is a medium severity cross-site scripting vulnerability found in dayrui XunRuiCMS versions up to 4.7.1. The vulnerability resides in the Add Display Name Field feature, specifically within the /admind45f74adbd95.php file, which handles requests to add fields. By manipulating the data[name] parameter, an attacker can inject malicious JavaScript code that executes in the context of an authenticated administrator’s browser session. The attack vector is remote and does not require prior authentication, but user interaction is necessary to trigger the malicious payload. The vulnerability arises from insufficient input validation or output encoding of the data[name] parameter, allowing script injection. The vendor was notified early but has not issued a patch or response, and no official remediation is currently available. Public exploit code has been released, increasing the likelihood of exploitation attempts. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:H indicates high privileges required, but the description suggests no authentication is needed, so this may be a discrepancy), user interaction required (UI:P), and limited impact on confidentiality and integrity. This vulnerability primarily threatens the integrity of the administrator’s session and the availability of the CMS interface through potential defacement or session hijacking. Given the lack of vendor response and public exploit availability, this vulnerability poses a tangible risk to organizations using XunRuiCMS versions 4.7.0 and 4.7.1.

The primary impact of CVE-2025-14005 is the potential for attackers to execute arbitrary scripts in the context of an administrator’s browser session, leading to session hijacking, credential theft, or unauthorized actions within the CMS. This can result in defacement of websites, unauthorized content changes, or further compromise of the underlying server if combined with other vulnerabilities. Organizations relying on XunRuiCMS for content management may face reputational damage, data integrity issues, and operational disruptions. Since the vulnerability can be exploited remotely and does not require authentication, attackers can target exposed administrative interfaces over the internet. The public availability of exploit code increases the risk of widespread attacks, especially against organizations that have not applied mitigations or workarounds. The lack of vendor response and absence of official patches prolong the exposure window, making timely mitigation critical. Overall, the vulnerability threatens the confidentiality and integrity of administrative sessions and the availability of the CMS-managed content.

1. Immediately restrict access to the administrative interface by IP whitelisting or VPN-only access to reduce exposure to remote attackers. 2. Implement web application firewall (WAF) rules to detect and block malicious payloads targeting the data[name] parameter in requests to /admind45f74adbd95.php. 3. Sanitize and validate all user inputs on the server side, especially the data[name] parameter, to prevent script injection. 4. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the administrator’s browser. 5. Monitor logs for suspicious requests targeting the vulnerable endpoint and unusual administrator session activity. 6. If possible, disable or remove the Add Display Name Field functionality temporarily until a vendor patch is available. 7. Engage with the vendor or community to encourage the release of an official patch or update. 8. Educate administrators to be cautious of phishing or social engineering attempts that could trigger the XSS payload. 9. Regularly back up CMS data and configurations to enable recovery in case of compromise. These steps go beyond generic advice by focusing on access control, input validation, and layered defenses specific to the vulnerable component and attack vector.
