💻 Affected Systems
- DataEase
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attacker to execute arbitrary commands, access sensitive data, and pivot to other systems.
Likely Case
Data breach through unauthorized database access and potential lateral movement within the network.
If Mitigated
Limited impact with proper network segmentation and minimal user privileges.
🎯 Exploit Status
Exploitation requires user access to modify data in DataEase. The advisory suggests RCE is possible through data injection.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v1.18.5
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-8wg2-9gwc-5fx2
Restart Required: Yes

🔧 Temporary Workarounds
Disable AWS Redshift Data Source
allTemporarily disable or remove AWS Redshift data source configurations until patching is complete.
# Remove Redshift data source connections from DataEase configuration
🧯 If You Can't Patch
- Implement strict network segmentation to isolate DataEase instances from critical systems
- Apply principle of least privilege to DataEase user accounts and monitor for suspicious data modification
🔍 How to Verify
Check if Vulnerable:
Check DataEase version and verify if AWS Redshift data sources are configured. Versions below 1.18.5 with Redshift connections are vulnerable.Check Version:
Check DataEase web interface admin panel or deployment configuration files for version informationVerify Fix Applied:
Confirm version is 1.18.5 or higher and test Redshift data source functionality.📡 Detection & Monitoring
