Overview
CVE-2025-14005 details a cross-site scripting (XSS) vulnerability found in dayrui XunRuiCMS up to version 4.7.1. This vulnerability allows a remote attacker to inject malicious scripts into the application, potentially compromising user accounts and data. The vendor has not responded to disclosure attempts.
Technical Details
The vulnerability exists within the “Add Display Name Field” functionality located in the /admind45f74adbd95.php?c=field&m=add&rname=site&rid=1&page=0 file. Specifically, the data[name] argument is susceptible to manipulation. An attacker can inject malicious JavaScript code into this parameter, which will then be executed in the context of other users accessing the same page. The vulnerability can be triggered remotely without authentication.
The publicly available exploit allows an attacker to inject arbitrary JavaScript code, which could be used to steal cookies, redirect users to malicious websites, or deface the website.
CVSS Analysis
- Severity: LOW
- CVSS Score: 2.4
The CVSS score of 2.4 indicates a low severity. This score reflects the limited impact as the vulnerability requires specific user interaction or a particular configuration to be exploited effectively. However, even low severity vulnerabilities should be addressed promptly to prevent potential abuse.
Possible Impact
While the CVSS score is low, the potential impact of this XSS vulnerability should not be ignored. Successful exploitation could lead to:
- Cookie theft: Attackers could steal user session cookies, allowing them to impersonate legitimate users.
- Website defacement: Injected scripts could modify the appearance of the website, damaging the site’s reputation.
- Redirection to malicious websites: Users could be redirected to phishing sites or sites hosting malware.
- Data theft: Although less likely due to the limited scope, sensitive data displayed on the affected page could be accessed.
Mitigation and Patch Steps
Since the vendor has not provided a patch or response, the following mitigation steps are recommended:
- Input Validation: Implement strict input validation and sanitization on all user-supplied data, especially for the
data[name]parameter in the affected file. This should be done server-side to prevent attackers from bypassing client-side checks. - Output Encoding: Encode all data before it is displayed in the web browser. Use appropriate encoding methods (e.g., HTML entity encoding) to prevent the browser from interpreting injected code as HTML or JavaScript.
- Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) with rules to detect and block XSS attacks. Configure the WAF to specifically filter out malicious input targeting the
data[name]parameter. - Consider Alternatives: If possible, consider migrating to a more actively maintained CMS or framework with a better security track record.
- Monitor for Suspicious Activity: Continuously monitor website logs for suspicious activity that may indicate an XSS attack. Pay close attention to requests containing potentially malicious code.
