Likely Case
Unauthorized database access, data manipulation, or privilege escalation within the DataEase application.
If Mitigated
Limited impact with proper network segmentation, minimal user privileges, and monitoring in place.
🎯 Exploit Status
The vulnerability involves bypassing a previous patch and constructing malicious JDBC statements, requiring some technical knowledge but no authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.10.10
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-6pq2-6q8x-mp2r
Restart Required: Yes
Instructions:
1. Backup your DataEase configuration and data. 2. Download version 2.10.10 from the official repository. 3. Stop the DataEase service. 4. Replace the installation with the new version. 5. Restart the service.
🔧 Temporary Workarounds
Network Isolation
allRestrict network access to DataEase instances to only trusted IP addresses.
Use firewall rules to limit inbound connections to DataEase ports (default 8080/8081) to authorized networks only.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate DataEase instances from critical systems.
- Enable detailed logging and monitoring for unusual JDBC connection attempts or payloads.
🔍 How to Verify
Check if Vulnerable:
Check the DataEase version in the web interface under Settings > About, or examine the application files for version markers.Check Version:
curl -s http://localhost:8080/api/settings/about | grep versionVerify Fix Applied:
Confirm the version is 2.10.10 or higher and test that malicious payloads attempting to bypass the previous patch are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual JDBC connection strings in application logs
- Failed authentication attempts followed by payload delivery
- Errors related to getUrlType() function
Network Indicators:
- Unexpected outbound database connections from DataEase servers
- HTTP requests containing suspicious JDBC parameters
SIEM Query:
