CVE-2024-37759
📋 TL;DR
DataGear v5.0.0 and earlier contains a Spring Expression Language (SpEL) injection vulnerability in the Data Viewing interface. This allows authenticated attackers to execute arbitrary code on the server with the same privileges as the DataGear application. Organizations using vulnerable versions of DataGear are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing remote code execution, data exfiltration, lateral movement, and persistent backdoor installation.
Likely Case
Unauthorized data access, privilege escalation, and potential server takeover by authenticated attackers.
If Mitigated
Limited impact with proper network segmentation, strong authentication, and input validation controls.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward with published PoC.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v5.0.1 or later
Vendor Advisory: https://github.com/datageartech/datagear/issues/32
Restart Required: Yes
Instructions:
1. Download DataGear v5.0.1 or later from official repository. 2. Backup current installation and data. 3. Stop DataGear service. 4. Replace with patched version. 5. Restart DataGear service.
🔧 Temporary Workarounds
Disable Data Viewing Interface
allTemporarily disable the vulnerable Data Viewing interface component
Modify DataGear configuration to disable data viewing functionality
Network Access Control
linuxRestrict access to DataGear interface to trusted IPs only
iptables -A INPUT -p tcp --dport [DataGear-port] -s [trusted-ip] -j ACCEPT
iptables -A INPUT -p tcp --dport [DataGear-port] -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate DataGear from critical systems
- Enforce strong authentication and limit user privileges to minimum required
🔍 How to Verify
Check if Vulnerable:
Check DataGear version via web interface or configuration files. Versions 5.0.0 and earlier are vulnerable.Check Version:
Check DataGear web interface or examine application.properties/version filesVerify Fix Applied:
Verify installation of DataGear v5.0.1 or later and test that SpEL injection attempts are properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual SpEL expressions in request logs
- Multiple failed authentication attempts followed by data viewing requests
- Unexpected system commands in application logs
Network Indicators:
- Unusual outbound connections from DataGear server
- Spike in traffic to DataGear data viewing endpoints
