The CVE-2025-XXXX vulnerability in Liferay Portal and Liferay DXP is a Cross-Site Scripting (XSS) issue that affects multiple versions of the platform. The vulnerability resides in the Frontend JS module’s `layout-taglib/liferay/index.js` file, specifically in the `toastData` parameter. Attackers can exploit this flaw by injecting arbitrary web scripts or HTML into the parameter, which is then executed in the context of the victim’s browser. This allows malicious actors to steal sensitive information, such as session cookies, or perform actions on behalf of the user without their consent. The vulnerability is classified as moderate due to the requirement of user interaction and the specific conditions needed for successful exploitation.
DailyCVE Form:
Platform: Liferay Portal/DXP
Version: 7.4.3.82-7.4.3.128, 2024.Q3.0, 2024.Q2.0-2024.Q2.13, 2024.Q1.1-2024.Q1.12, 2023.Q4.0-2023.Q4.10, 2023.Q3.1-2023.Q3.10
Vulnerability: XSS
Severity: Moderate
Date: Mar 19, 2025
What Undercode Say:
Exploitation:
- Payload Injection: Craft a malicious payload to inject into the `toastData` parameter.
<script>alert('XSS')</script> - Exploit URL: Construct a URL with the payload.
https://target-site.com/page?toastData=<script>alert('XSS')</script> - Social Engineering: Trick users into clicking the malicious link.
Protection:
- Input Validation: Sanitize user inputs to prevent script injection.
function sanitizeInput(input) { return input.replace(/<script.?>.?<\/script>/gi, ''); } - Content Security Policy (CSP): Implement CSP headers to restrict script execution.
Content-Security-Policy: default-src 'self'; script-src 'self';
- Patch Installation: Update to the patched versions (2024.Q1.13, 2024.Q4.0, 2024.Q3.1).
Analytics:
- Affected Users: Organizations using Liferay Portal/DXP versions within the affected range.
- Risk Level: Moderate, due to user interaction requirement.
- Exploit Prevalence: Likely low, but potential for targeted attacks.
Commands:
1. Check Version: Verify the installed Liferay version.
cat /path/to/liferay/version.txt
2. Update Command: Apply the latest patches.
sudo apt-get update && sudo apt-get install liferay-patched-version
Code Snippets:
1. Sanitization Function:
function sanitizeToastData(toastData) {
const div = document.createElement('div');
div.textContent = toastData;
return div.innerHTML;
}
2. CSP Header Implementation:
add_header Content-Security-Policy "default-src 'self'; script-src 'self';";
By following these steps, organizations can mitigate the risk posed by this XSS vulnerability in Liferay Portal and Liferay DXP.
