CVE-2025-43748
📋 TL;DR
This CVE describes a Cross-Site Request Forgery (CSRF) vulnerability affecting omni-administrator users in Liferay Portal and DXP. Attackers can trick authenticated administrators into performing unintended actions via malicious requests. All Liferay deployments with omni-administrator accounts using affected versions are vulnerable.
💻 Affected Systems
- Liferay Portal
- Liferay DXP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could gain full administrative control by tricking omni-administrators into executing privileged actions like creating new admin accounts, modifying system configurations, or deploying malicious code.
Likely Case
Attackers could modify user permissions, change system settings, or perform data manipulation through the administrator interface without the victim's knowledge.
If Mitigated
With proper CSRF protections and security controls, the impact is limited to unsuccessful exploitation attempts that are blocked by security mechanisms.
🎯 Exploit Status
Requires social engineering to trick authenticated omni-administrator users into visiting malicious pages while logged into Liferay.

allAdd CSRF protection to administrative endpoints using custom filters or security configurations
Restrict Administrator Access
allLimit omni-administrator access to trusted networks and implement strict session management
🧯 If You Can't Patch
- Implement network segmentation to restrict omni-administrator access to trusted IP addresses only
- Enforce strict session timeouts and require re-authentication for sensitive administrative actions
🔍 How to Verify
Check if Vulnerable:
Check Liferay version via Control Panel → Configuration → Server Administration → System InformationCheck Version:
Check Liferay version in Control Panel or via server logsVerify Fix Applied:
Verify version is patched and test CSRF protection on administrative endpoints📡 Detection & Monitoring
Log Indicators:
- Multiple administrative actions from same session in rapid succession
- Administrative requests missing CSRF tokens
Network Indicators:
- External requests to administrative endpoints from unexpected sources
SIEM Query:
