CVE-2025-14005 identifies a cross-site scripting vulnerability in dayrui XunRuiCMS, specifically affecting versions 4.7.0 and 4.7.1. The vulnerability resides in the Add Display Name Field feature accessed via the /admind45f74adbd95.php file with parameters c=field&m=add&rname=site&rid=1&page=0. An attacker can manipulate the data[name] argument to inject malicious scripts, which are then executed in the context of an authenticated administrator's browser. This XSS flaw is remotely exploitable without requiring prior authentication but does require user interaction, such as clicking a crafted link or visiting a malicious page. The vulnerability impacts the confidentiality and integrity of the administrator's session, potentially allowing session hijacking, credential theft, or unauthorized actions within the CMS. The CVSS 4.0 base score is 4.8 (medium), reflecting the need for administrator privileges and user interaction for exploitation. The vendor was notified early but has not issued any patches or advisories, and although a public exploit exists, no confirmed active exploitation in the wild has been reported. The lack of vendor response and patch availability increases risk for organizations relying on this CMS. The vulnerability is particularly concerning for organizations with internet-facing CMS admin panels, as successful exploitation could lead to broader compromise of the CMS environment and associated data.

For European organizations, this vulnerability poses a moderate risk primarily to those using dayrui XunRuiCMS versions 4.7.0 or 4.7.1, especially if the CMS admin interface is exposed to the internet. Successful exploitation could lead to session hijacking of administrators, unauthorized content modification, or deployment of malicious payloads within the CMS environment. This could result in data integrity loss, defacement, or further compromise of internal networks. Given the CMS's role in managing website content, attackers could leverage this to distribute malware or phishing content to end users, damaging organizational reputation and potentially violating data protection regulations such as GDPR. The absence of vendor patches and public exploit availability increases the urgency for mitigation. The impact is somewhat limited by the requirement for administrator interaction and privileges, but the risk remains significant for organizations with lax access controls or insufficient network segmentation.

1. Immediately restrict access to the vulnerable admin endpoint (/admind45f74adbd95.php) using network-level controls such as IP whitelisting or VPN-only access to reduce exposure. 2. Implement strict input validation and output encoding on the data[name] parameter and other user-controllable inputs to prevent script injection. 3. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts within the CMS admin interface. 4. Monitor web server and application logs for unusual requests targeting the vulnerable endpoint or suspicious parameter values. 5. Educate administrators about the risk of clicking untrusted links or opening suspicious content while logged into the CMS. 6. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block XSS attack patterns targeting this vulnerability. 7. Plan for CMS upgrade or patching once vendor releases a fix; meanwhile, consider isolating the CMS environment to limit lateral movement. 8. Conduct regular security assessments of CMS installations to identify and remediate similar vulnerabilities proactively.
