CVE-2024-47074
📋 TL;DR
This vulnerability in DataEase allows attackers to execute arbitrary system commands by exploiting PostgreSQL JDBC deserialization through unfiltered user input in JDBC connection parameters. Attackers can achieve remote code execution and gain server privileges. All DataEase instances with PostgreSQL data sources configured are affected.
💻 Affected Systems
- DataEase
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Full server compromise with attacker gaining root/system privileges, data exfiltration, lateral movement, and persistent backdoor installation.
Likely Case
Remote code execution leading to data theft, service disruption, and potential ransomware deployment.
If Mitigated
Limited impact if network segmentation prevents outbound connections to attacker-controlled PostgreSQL servers.
🎯 Exploit Status
Exploitation requires attacker to control a malicious PostgreSQL server, but the vulnerability itself is straightforward to exploit once that condition is met.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v1.18.25
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-jgg7-w629-wcpc
Restart Required: Yes
Instructions:
1. Backup your DataEase instance and data. 2. Download v1.18.25 from official repository. 3. Stop DataEase service. 4. Replace with patched version. 5. Restart DataEase service. 6. Verify functionality.
🔧 Temporary Workarounds
Network Restriction
linuxBlock outbound connections from DataEase servers to PostgreSQL servers except to trusted, known-good PostgreSQL instances.
iptables -A OUTPUT -p tcp --dport 5432 -j DROP
iptables -A OUTPUT -p tcp --dport 5432 -d TRUSTED_IP -j ACCEPT
Disable PostgreSQL Data Sources
allTemporarily disable PostgreSQL data source functionality if not required.
🧯 If You Can't Patch
- Implement strict network segmentation to prevent DataEase servers from connecting to untrusted PostgreSQL instances.
- Monitor for unusual outbound connections to PostgreSQL ports (5432) from DataEase servers.
🔍 How to Verify
Check if Vulnerable:
Check DataEase version via web interface or configuration files. Versions below v1.18.25 are vulnerable.Check Version:
Check DataEase web interface admin panel or examine application configuration files for version information.Verify Fix Applied:
Confirm version is v1.18.25 or higher and test PostgreSQL data source functionality works normally.📡 Detection & Monitoring
Log Indicators:
- Unusual JDBC connection strings in DataEase logs
- Failed or unusual PostgreSQL connection attempts
- System command execution from DataEase process
Network Indicators:
- Outbound connections from DataEase server to unknown PostgreSQL servers on port 5432
- Unusual network traffic patterns from DataEase process
