CVE-2025-43790
📋 TL;DR
This CVE describes an Insecure Direct Object Reference (IDOR) vulnerability in Liferay Portal and DXP that allows authenticated users to access, create, edit, and relate data across different virtual instances. Attackers can manipulate object references to perform unauthorized operations on data belonging to other virtual instances. This affects Liferay Portal 7.4.0-7.4.3.124 and Liferay DXP 2024.Q2.0-2024.Q2.6, 2024.Q1.1-2024.Q1.12, and 7.4 GA through update 92.
💻 Affected Systems
- Liferay Portal
- Liferay DXP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of data isolation between virtual instances, allowing authenticated attackers to read, modify, delete, or create data in any virtual instance, potentially leading to data breaches, privilege escalation, or service disruption.
Likely Case
Unauthorized access to sensitive data across virtual instances, data manipulation, and potential privilege escalation within the affected Liferay deployment.
If Mitigated
Limited impact with proper access controls, monitoring, and network segmentation, though the vulnerability still exists at the application layer.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once authenticated. IDOR vulnerabilities typically involve manipulating object identifiers in requests.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Liferay Portal 7.4.3.125 or later; Liferay DXP 2024.Q2.7 or later, 2024.Q1.13 or later, or 7.4 update 93 or later
Vendor Advisory: https://liferay.dev/portal/security/known-vulnerabilities/-/asset_publisher/jekt/content/CVE-2025-43790
Restart Required: Yes
Instructions:
1. Download the appropriate patch from Liferay's customer portal. 2. Apply the patch following Liferay's patching procedures. 3. Restart the Liferay server. 4. Verify the fix by testing virtual instance isolation.
🔧 Temporary Workarounds
Temporary Access Restriction
allImplement strict access controls and monitoring for authenticated users to limit potential exploitation.
🧯 If You Can't Patch
- Implement network segmentation to isolate virtual instances at the network level.
- Enhance monitoring and alerting for unusual cross-instance data access patterns.
🔍 How to Verify
Check if Vulnerable:
Check the Liferay version against affected ranges. Test if authenticated users can access data across virtual instances by manipulating object IDs.Check Version:
Check the Liferay version in the Control Panel under Configuration > Server Administration > Properties, or via the Liferay API.Verify Fix Applied:
After patching, verify that authenticated users can no longer access, create, edit, or relate data across different virtual instances.📡 Detection & Monitoring
Log Indicators:
- Unusual access patterns across virtual instances
- Failed authorization attempts for cross-instance operations
- Modifications to data in unexpected virtual instances
Network Indicators:
- Increased authenticated requests to object endpoints with manipulated IDs
SIEM Query:
Example: 'source="liferay" AND (event_type="data_access" OR event_type="data_modification") AND virtual_instance_change="true"'
