CVE-2025-62249
📋 TL;DR
A reflected cross-site scripting (XSS) vulnerability in Liferay Portal and DXP allows remote unauthenticated attackers to inject malicious JavaScript into the google_gadget component. This affects users of Liferay Portal 7.4.0-7.4.3.132 and multiple Liferay DXP versions from 2023.Q4 through 2025.Q3. Attackers can execute arbitrary JavaScript in victims' browsers when they visit a specially crafted URL.

- Liferay DXP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or install malware via drive-by downloads.
Likely Case
Session hijacking, credential theft, or defacement of the affected page through injected content.
If Mitigated
With proper input validation and output encoding, the impact is limited to potential UI disruption without data compromise.
🎯 Exploit Status
Exploitation requires user interaction (clicking a malicious link) but is straightforward for attackers with basic web skills.

Navigate to Control Panel > Configuration > System Settings > Third Party > Google Gadget and disable it.
Implement WAF rules
allConfigure web application firewall to block requests containing suspicious JavaScript patterns in URL parameters.
Add WAF rule: Block requests with patterns like <script> or javascript: in query strings.
🧯 If You Can't Patch
- Implement strict Content Security Policy (CSP) headers to restrict script execution.
- Use input validation and output encoding on the google_gadget component manually.
🔍 How to Verify
Check if Vulnerable:
Test by injecting a simple script like <script>alert('test')</script> into the google_gadget parameter via URL and check if it executes.Check Version:
Check Liferay version via Control Panel > Server Administration > Properties or run: grep 'liferay.version' in Liferay installation directory.Verify Fix Applied:
After patching, repeat the test; the script should be properly encoded and not execute.📡 Detection & Monitoring
Log Indicators:
- Look for HTTP requests with suspicious strings like <script>, javascript:, or eval() in URL parameters related to google_gadget.
