CVE-2023-49898
📋 TL;DR
This vulnerability in Apache StreamPark allows authenticated users with system-level permissions to execute arbitrary commands through Maven compilation parameters. Attackers could achieve remote code execution by injecting malicious commands into the build process. Only authenticated users with administrative privileges are affected.
💻 Affected Systems
- Apache StreamPark
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control over the server, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Limited impact since exploitation requires authenticated administrative access; most likely scenario is insider threat or compromised admin credentials leading to targeted attacks.
If Mitigated
Minimal risk with proper access controls, least privilege principles, and network segmentation limiting the blast radius of any successful exploitation.
🎯 Exploit Status
Example exploitation commands provided in advisory; requires authenticated admin access to the StreamPark interface.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.1.2
Vendor Advisory: https://lists.apache.org/thread/qj99c03r4td35f8gbxq084b8qmv2fyr3
Restart Required: Yes
Instructions:
1. Backup current configuration and data. 2. Download StreamPark version 2.1.2 or later from official Apache repository. 3. Stop the StreamPark service. 4. Replace existing installation with new version. 5. Restart the StreamPark service. 6. Verify functionality.
🔧 Temporary Workarounds
Restrict Administrative Access
allLimit system-level permissions to only essential personnel and implement strong authentication controls.
Network Segmentation
allIsolate StreamPark instances from critical systems and implement strict outbound network controls.
🧯 If You Can't Patch
- Implement strict least privilege access controls for StreamPark administrative accounts
- Monitor and audit all administrative actions within StreamPark, particularly Maven compilation operations
🔍 How to Verify
Check if Vulnerable:
Check StreamPark version; if version is earlier than 2.1.2, the system is vulnerable.Check Version:
Check StreamPark web interface or configuration files for version informationVerify Fix Applied:
Confirm StreamPark version is 2.1.2 or later and test that command injection in Maven parameters is no longer possible.📡 Detection & Monitoring
Log Indicators:
- Unusual Maven compilation commands
- Suspicious command sequences in build logs
- Administrative user performing unexpected compilation operations
Network Indicators:
- Outbound connections from StreamPark server to unexpected destinations
- Unusual network traffic patterns following build operations
