CVE-2024-52295
📋 TL;DR
CVE-2024-52295 is a critical authentication bypass vulnerability in DataEase where attackers can forge JWT tokens due to hardcoded secrets and identifiers. This allows complete service takeover of affected DataEase instances. All DataEase deployments prior to version 2.10.2 are vulnerable.
💻 Affected Systems
- DataEase
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the DataEase instance allowing attackers to access, modify, or delete all data, execute arbitrary code, and pivot to other systems.
Likely Case
Unauthorized access to sensitive data visualization dashboards and underlying data sources, potentially leading to data theft or manipulation.
If Mitigated
Limited impact if proper network segmentation and access controls prevent external access, but internal threats remain.
🎯 Exploit Status
Exploitation requires understanding JWT token structure but is straightforward once the hardcoded values are identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.10.2
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-45v9-gfcv-xcq6
Restart Required: Yes
Instructions:
1. Backup your DataEase instance and data. 2. Stop the DataEase service. 3. Upgrade to version 2.10.2 using your deployment method (Docker, binary, etc.). 4. Restart the service. 5. Verify the upgrade was successful.
🔧 Temporary Workarounds
Network Isolation
allRestrict network access to DataEase instances to only trusted IP addresses or internal networks.
Use firewall rules to block external access to DataEase ports (default: 80, 443, 8080)
🧯 If You Can't Patch
- Immediately isolate vulnerable instances from internet access and untrusted networks
- Implement strict network monitoring for unusual authentication patterns or JWT token usage
🔍 How to Verify
Check if Vulnerable:
Check DataEase version via web interface or configuration files. Versions below 2.10.2 are vulnerable.Check Version:
Check DataEase web interface or docker inspect for version informationVerify Fix Applied:
Confirm version is 2.10.2 or higher and test that JWT tokens with old hardcoded values no longer work.📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts followed by successful logins with unusual patterns
- JWT token validation errors or unusual token formats
Network Indicators:
- Unusual source IPs accessing authentication endpoints
- Multiple authentication requests in short timeframes
