Organizations using vulnerable versions of this open-source BI tool are at risk of complete system compromise.
💻 Affected Systems
- DataEase
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise leading to data theft, ransomware deployment, lateral movement across the network, and persistent backdoor installation.
Likely Case
Attackers gain shell access to the DataEase server, allowing them to exfiltrate database credentials, manipulate BI reports, and pivot to other systems.
If Mitigated
With proper network segmentation and least privilege access, impact could be limited to the DataEase application server only.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once credentials are obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.10.9
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-hxw4-vpfp-frgv
Restart Required: Yes
Instructions:
1. Backup your DataEase configuration and data. 2. Download version 2.10.9 from the official repository. 3. Stop the DataEase service. 4. Replace the installation with the patched version. 5. Restart the service and verify functionality.
🔧 Temporary Workarounds
Disable JDBC Link Functionality
allTemporarily disable the vulnerable JDBC link feature until patching can be completed.
# Modify DataEase configuration to disable JDBC connections
# Specific commands depend on deployment method
Restrict User Permissions
allLimit authenticated users' access to only essential functions, removing JDBC link permissions.
# Review and modify user role permissions in DataEase admin panel
🧯 If You Can't Patch
- Implement strict network segmentation to isolate DataEase servers from critical systems
- Enforce multi-factor authentication and monitor for suspicious user activity
🔍 How to Verify
Check if Vulnerable:
Check the DataEase version in the web interface admin panel or configuration files.Check Version:
Check web interface or examine version.txt in installation directoryVerify Fix Applied:
Verify the version shows 2.10.9 or higher and test that JDBC functionality works without allowing code execution.📡 Detection & Monitoring
