CVE-2025-4581
📋 TL;DR
This CVE describes a pre-authentication blind Server-Side Request Forgery (SSRF) vulnerability in Liferay Portal and DXP. Attackers can force vulnerable servers to make arbitrary HTTP requests to internal systems without authentication, potentially exposing internal networks. Affected versions include Liferay Portal 7.4.0-7.4.3.132 and multiple DXP versions from 2024.Q1 through 2025.Q1.
💻 Affected Systems
- Liferay Portal
- Liferay DXP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete internal network enumeration leading to lateral movement, credential theft from internal services, and exploitation of other vulnerable internal systems.
Likely Case
Internal network scanning and service discovery, potentially exposing sensitive internal endpoints and metadata.
If Mitigated
Limited impact if proper network segmentation and egress filtering are in place, though initial reconnaissance may still occur.
🎯 Exploit Status
Exploitation requires no authentication and minimal technical skill. The vulnerability is in a specific web component with predictable behavior.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Liferay Portal 7.4.3.133+, Liferay DXP 2025.Q1.5+, 2024.Q4.8+, 2024.Q3.14+, 2024.Q2.14+, 2024.Q1.16+, 7.4 update 93+

Restart Required: Yes
Instructions:
1. Download appropriate patch from Liferay Customer Portal. 2. Apply patch following Liferay's patching procedures. 3. Restart Liferay instance. 4. Verify patch application via version check.
🔧 Temporary Workarounds
Disable OpenSSO Authentication Module
allRemove or disable the vulnerable portal-settings-authentication-opensso-web module if not required.
Navigate to Control Panel > Apps > App Manager > Installed Apps
Find 'OpenSSO Authentication' module
Click 'Deactivate' or 'Uninstall'
Network Egress Filtering
allImplement firewall rules to restrict outbound HTTP/HTTPS requests from Liferay servers to only necessary external services.
Configure firewall to block outbound requests from Liferay server except to whitelisted destinations
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Liferay servers from sensitive internal networks.
- Deploy web application firewall (WAF) with SSRF protection rules to block exploitation attempts.
🔍 How to Verify
Check if Vulnerable:
Check Liferay version via Control Panel > Server Administration > Properties. Look for version numbers in affected ranges.Check Version:
Check via Liferay UI or examine liferay-portal.properties file for version information.Verify Fix Applied:
Verify version is updated to patched versions: Portal 7.4.3.133+ or DXP versions beyond affected ranges.📡 Detection & Monitoring
