CVE-2025-43782
📋 TL;DR
An Insecure Direct Object Reference (IDOR) vulnerability in Liferay Portal and DXP allows authenticated users to access workflow definitions by name via API calls they shouldn't have permission to view. This affects Liferay Portal 7.4.0-7.4.3.124 and Liferay DXP 2024.Q2.0-2024.Q2.7, 2024.Q1.1-2024.Q1.12, and 7.4 GA-update 92. The vulnerability enables unauthorized access to sensitive workflow configuration data.
💻 Affected Systems
- Liferay Portal
- Liferay DXP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could exfiltrate sensitive workflow definitions containing business logic, approval processes, or internal system information, potentially enabling further attacks or business process manipulation.
Likely Case
Authenticated users (including low-privileged accounts) accessing workflow definitions they shouldn't see, potentially learning about internal processes or finding other vulnerabilities in workflow logic.
If Mitigated
Minimal impact with proper access controls and monitoring, as the vulnerability only exposes workflow definitions (not execution or data modification).
🎯 Exploit Status
Exploitation requires authenticated access and knowledge of API endpoints; attackers need to guess or discover workflow definition names.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Liferay Portal 7.4.3.125+, Liferay DXP 2024.Q2.8+, 2024.Q1.13+, 7.4 update 93+
Vendor Advisory: https://liferay.dev/portal/security/known-vulnerabilities/-/asset_publisher/jekt/content/CVE-2025-43782
Restart Required: No
Instructions:
1. Download appropriate fix pack from Liferay Customer Portal. 2. Apply fix pack following Liferay documentation. 3. Verify version update. 4. Test workflow functionality.
🔧 Temporary Workarounds
API Access Restriction
allImplement API gateway or web application firewall rules to restrict access to workflow definition endpoints.
Enhanced Monitoring
allIncrease logging and monitoring of API calls to workflow definition endpoints.
🧯 If You Can't Patch
- Implement strict access controls and principle of least privilege for authenticated users
- Monitor API logs for unusual access patterns to workflow definition endpoints
🔍 How to Verify
Check if Vulnerable:
Check Liferay version via Control Panel → Configuration → Server Administration → System InformationCheck Version:
Check via Liferay Control Panel or database query: SELECT buildNumber, buildDate FROM Release_Verify Fix Applied:
Verify version is updated to patched version and test API access to workflow definitions with unauthorized users📡 Detection & Monitoring
Log Indicators:
- Unauthorized API calls to /api/workflow-definitions endpoints
- Multiple failed attempts to access workflow definitions
Network Indicators:
- Unusual patterns of API requests to workflow endpoints from authenticated users
SIEM Query:
source="liferay-logs" AND (uri_path="/api/workflow-definitions" OR endpoint="workflow-definition") AND user_role!="admin"
