CVE-2025-62248
📋 TL;DR
A reflected cross-site scripting (XSS) vulnerability in Liferay Portal and DXP allows authenticated attackers to inject malicious JavaScript via a specific parameter. When victims access crafted URLs containing this parameter, the script executes in their browsers. This affects authenticated users of vulnerable Liferay versions.
💻 Affected Systems
- Liferay Portal
- Liferay DXP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform actions as the victim, redirect to malicious sites, or capture sensitive data entered by users.
Likely Case
Session hijacking, credential theft, or defacement of user interfaces through injected content.
If Mitigated
With proper input validation and output encoding, the impact is limited to unsuccessful injection attempts.
🎯 Exploit Status
Exploitation requires crafting malicious URLs and tricking authenticated users into clicking them; no public exploit code known

🔧 Temporary Workarounds
Input Validation Filter
allImplement a web application firewall (WAF) or custom filter to sanitize the _com_liferay_dynamic_data_mapping_web_portlet_DDMPortlet_definition parameter
🧯 If You Can't Patch
- Implement strict Content Security Policy (CSP) headers to block inline script execution
- Monitor and block suspicious URLs containing the vulnerable parameter in web server logs
🔍 How to Verify
Check if Vulnerable:
Test by accessing a URL with the parameter _com_liferay_dynamic_data_mapping_web_portlet_DDMPortlet_definition containing a simple XSS payload like <script>alert('test')</script> and check if it executesCheck Version:
Check Liferay version via Control Panel > Configuration > Server Administration or review liferay-portal.xmlVerify Fix Applied:
After patching, repeat the vulnerability test; the script should not execute and the input should be properly sanitized📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing _com_liferay_dynamic_data_mapping_web_portlet_DDMPortlet_parameter with script tags or JavaScript code
- Unusual parameter values in access logs
Network Indicators:
