Overview
A cross-site scripting (XSS) vulnerability, identified as CVE-2025-14006, has been discovered in dayrui XunRuiCMS up to version 4.7.1. This vulnerability resides within the “Add Data Validation Page” component, specifically affecting the /admind45f74adbd95.php?c=field&m=add&rname=site&rid=1&page=1 file. By manipulating the data[name] argument, a remote attacker can inject malicious scripts that execute in the context of other users’ browsers. The vendor has been notified but has not provided a response.
Technical Details
The vulnerability stems from insufficient input validation of the data[name] parameter in the “Add Data Validation Page” functionality. An attacker can inject arbitrary JavaScript code within this parameter. When a user views the page containing the injected script, the malicious code will execute, potentially allowing the attacker to steal cookies, redirect users to phishing sites, or perform other malicious actions.
The vulnerable file is: /admind45f74adbd95.php?c=field&m=add&rname=site&rid=1&page=1
The vulnerable parameter is: data[name]
Example Payload (Proof of Concept – DO NOT USE IN PRODUCTION):
data[name]=<script>alert("XSS Vulnerability!");</script>CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns this vulnerability a score of 3.5, indicating a LOW severity. This score reflects the fact that the vulnerability requires user interaction and the impact is limited.
- CVSS Score: 3.5
- Attack Vector: Network
- Attack Complexity: Low
- Privileges Required: None
- User Interaction: Required
- Scope: Unchanged
- Confidentiality Impact: Low
- Integrity Impact: Low
- Availability Impact: None
Possible Impact
While the CVSS score is low, the potential impact should not be ignored. Successful exploitation of this XSS vulnerability could lead to:
- Cookie Theft: Attackers could steal user cookies, potentially gaining unauthorized access to user accounts.
- Phishing Attacks: Users could be redirected to fake login pages designed to steal their credentials.
- Defacement: The attacker could modify the appearance of the affected page.
- Malware Distribution: Malicious scripts could be used to distribute malware.
Mitigation or Patch Steps
Unfortunately, since the vendor has not responded, there is no official patch available at this time. However, you can implement the following mitigation strategies:
- Input Validation: Implement robust input validation on the server-side for the
data[name]parameter. Sanitize all input to remove or escape potentially malicious characters. - Output Encoding: Encode all output displayed on the page to prevent the browser from interpreting injected scripts.
- Web Application Firewall (WAF): Deploy a WAF to detect and block XSS attacks. Configure the WAF with rules specifically designed to mitigate XSS vulnerabilities.
- Content Security Policy (CSP): Implement a strong CSP to restrict the sources from which the browser can load resources.
- Monitor for Suspicious Activity: Closely monitor your XunRuiCMS instance for any unusual or suspicious activity that might indicate an attempted exploitation.
- Disable the affected functionality: If the “Add Data Validation Page” functionality is not critical, consider temporarily disabling it until a patch is available.
