CVE-2025-62267
📋 TL;DR
This CVE describes multiple cross-site scripting (XSS) vulnerabilities in Liferay Portal and DXP that allow remote attackers to inject malicious scripts or HTML into user profile fields. Attackers can execute arbitrary code in victims' browsers when they view compromised user profiles. Affected users include anyone running vulnerable versions of Liferay Portal 7.4.3.35-7.4.3.111 or Liferay DXP 2023.Q4.0-2023.Q4.10, 2023.Q3.1-2023.Q3.10, or 7.4 update 35-92.
💻 Affected Systems
- Liferay Portal
- 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 on user systems.
Likely Case
Session hijacking, credential theft, defacement of user profiles, or phishing attacks against other users.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Requires user interaction (viewing a malicious user profile) and some social engineering to be effective.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Liferay Portal 7.4.3.112+, Liferay DXP 2023.Q4.11+, 2023.Q3.11+, 7.4 update 93+
Vendor Advisory: https://liferay.dev/portal/security/known-vulnerabilities/-/asset_publisher/jekt/content/CVE-2025-62267
Restart Required: No
Instructions:
1. Download the latest patch from Liferay's customer portal. 2. Apply the patch according to Liferay's patching documentation. 3. Verify the fix by testing user profile fields for XSS vulnerabilities.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation and sanitization of user input in First Name, Middle Name, and Last Name fields.
Content Security Policy (CSP)
allImplement strict CSP headers to prevent execution of injected scripts.
🧯 If You Can't Patch
- Disable user profile editing functionality for non-administrative users
- Implement web application firewall (WAF) rules to block XSS payloads in user input fields
🔍 How to Verify
Check if Vulnerable:
Test by attempting to inject XSS payloads into First Name, Middle Name, or Last Name fields and checking if they execute when viewing the user profile.Check Version:
Check Liferay version in Control Panel → Configuration → Server Administration → System InformationVerify Fix Applied:
After patching, attempt the same XSS payloads and verify they are properly sanitized or blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual script tags or JavaScript in user profile fields
- Multiple failed XSS attempts in web server logs
Network Indicators:
- Suspicious characters or patterns in HTTP POST requests to user profile endpoints
SIEM Query:
source="web_server_logs" AND (uri_path="/api/jsonws/user/update-user" OR uri_path="/web/guest/home") AND (http_method="POST" OR http_method="PUT") AND (request_body CONTAINS "<script>" OR request_body CONTAINS "javascript:")
