CVE-2024-38363
📋 TL;DR
This vulnerability allows authenticated remote attackers to execute arbitrary code on Airbyte servers via Server-Side Template Injection (SSTI) in the connection builder docker image. Attackers can compromise the web server user account and potentially access sensitive credentials used in connector testing. Organizations running vulnerable Airbyte instances with authenticated access are affected.

⚠️ Risk & Real-World Impact
Worst Case
Full server compromise leading to credential theft, data exfiltration, and lateral movement within the network.
Likely Case
Unauthorized code execution allowing attackers to steal credentials from connector tests and potentially pivot to other systems.
If Mitigated
Limited impact due to network segmentation and restricted access, with only isolated container compromise.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once authenticated. The vulnerability is in a template rendering mechanism.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.62.2
Vendor Advisory: https://github.com/airbytehq/airbyte/security/advisories/GHSA-4j3c-fgvx-xgqq
Restart Required: Yes
Instructions:
1. Update Airbyte to version 0.62.2 or later. 2. Restart all Airbyte services. 3. Verify the update completed successfully.
🔧 Temporary Workarounds
Disable Connection Builder Access
allRestrict or disable access to the connection builder functionality for non-essential users.
Configure access controls in Airbyte settings or network firewall rules.
Network Segmentation
allIsolate Airbyte instances from sensitive networks and implement strict firewall rules.
Configure firewall to restrict inbound access to Airbyte web interface.
🧯 If You Can't Patch
- Implement strict authentication controls and limit user access to essential personnel only.
- Monitor for suspicious activity in Airbyte logs and network traffic to/from the instance.
🔍 How to Verify
Check if Vulnerable:
Check Airbyte version via web interface or by inspecting running containers: docker ps | grep airbyteCheck Version:
docker exec <airbyte_container> cat /app/version.txtVerify Fix Applied:
Confirm version is 0.62.2 or later in Airbyte web interface or via version check command.📡 Detection & Monitoring
