CVE-2024-23328
📋 TL;DR
This CVE describes a deserialization vulnerability in Dataease's MySQL datasource component that allows attackers to bypass JDBC attack blacklists. Successful exploitation enables arbitrary code execution or arbitrary file reading on affected systems. All Dataease users running vulnerable versions are affected.
💻 Affected Systems
- Dataease
📦 What is this software?
Dataease by Dataease
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with remote code execution leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Arbitrary code execution with application user privileges, potentially leading to data exfiltration, credential theft, or installation of backdoors.
If Mitigated
Limited impact due to network segmentation, minimal privileges, and proper input validation preventing successful exploitation.
🎯 Exploit Status
Exploitation requires understanding of Java deserialization attacks and JDBC connection string manipulation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.18.15 or 2.3.0
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-8x8q-p622-jf25
Restart Required: Yes
Instructions:
1. Backup your Dataease configuration and data. 2. Stop the Dataease service. 3. Upgrade to version 1.18.15 (for v1.x) or 2.3.0 (for v2.x). 4. Restart the Dataease service. 5. Verify the upgrade was successful.
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to Dataease MySQL datasource connections to trusted sources only.
Input Validation
allImplement strict validation of MySQL connection strings and datasource configurations.
🧯 If You Can't Patch
- Implement network controls to restrict access to Dataease MySQL datasource endpoints
- Disable or remove MySQL datasource configurations if not required
🔍 How to Verify
Check if Vulnerable:
Check Dataease version via web interface or configuration files; versions below 1.18.15 or 2.3.0 are vulnerable.Check Version:
Check Dataease web interface admin panel or examine application configuration files for version information.Verify Fix Applied:
Verify version is 1.18.15 or higher (for v1.x) or 2.3.0 or higher (for v2.x) after upgrade.📡 Detection & Monitoring
Log Indicators:
- Unusual MySQL connection strings in datasource logs
- Java deserialization errors in application logs
- Unexpected outbound connections from Dataease server
Network Indicators:
