CVE-2024-29737
📋 TL;DR
This vulnerability in Apache StreamPark allows authenticated users with system-level permissions to execute arbitrary commands through improper input validation in the project module's build arguments. Attackers can inject commands via backticks in build arguments, leading to remote command execution. Only authenticated users with administrative privileges are affected.
💻 Affected Systems
- Apache StreamPark
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated malicious administrator could execute arbitrary commands on the server, potentially leading to complete system compromise, data theft, or lateral movement.
Likely Case
Accidental command injection by legitimate users or limited exploitation by compromised administrator accounts resulting in unauthorized command execution.
If Mitigated
With proper access controls and monitoring, impact is limited to authorized administrative actions with audit trails.
🎯 Exploit Status
Exploitation requires authenticated access with administrative privileges. Public proof-of-concept demonstrates command injection via backtick characters in build arguments.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.1.4
Vendor Advisory: https://lists.apache.org/thread/xhx7jt1t24s6d7o435wxng8t0ojfbfh5
Restart Required: Yes
Instructions:
1. Backup current configuration and data. 2. Download StreamPark 2.1.4 from official Apache repository. 3. Stop the StreamPark service. 4. Replace with version 2.1.4. 5. Restart the service. 6. Verify functionality.
🔧 Temporary Workarounds
Input validation at proxy/WAF
allImplement input validation to block backtick characters in build argument parameters
Restrict administrative access
allLimit system-level permissions to only essential users and implement multi-factor authentication
🧯 If You Can't Patch
- Implement strict input validation at the application layer to filter backtick characters
- Restrict build argument functionality to trusted users only and implement command whitelisting
🔍 How to Verify
Check if Vulnerable:
Check if StreamPark version is below 2.1.4 and test if backtick characters are accepted in project build argumentsCheck Version:
Check StreamPark web interface or configuration files for version informationVerify Fix Applied:
After upgrading to 2.1.4, attempt to input backtick characters in build arguments and verify they are rejected or escaped📡 Detection & Monitoring
Log Indicators:
- Unusual command execution in build logs
- Backtick characters in build argument parameters
- Multiple failed build attempts with special characters
Network Indicators:
- Unusual outbound connections from StreamPark server during build processes
