CVE-2024-39934
📋 TL;DR
Robotmk versions before 2.0.1 contain a privilege escalation vulnerability where local users can gain SYSTEM privileges when automated Python environment setup is enabled. This occurs because the 'shared holotree usage' feature allows any user to modify any Python environment. Systems running Robotmk with automated Python environment setup are affected.
💻 Affected Systems
- Robotmk
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

⚠️ Risk & Real-World Impact
Worst Case
Local attacker gains full SYSTEM privileges, enabling complete system compromise, data theft, persistence installation, and lateral movement.
Likely Case
Local user escalates to administrative privileges, potentially installing malware, accessing sensitive data, or disrupting operations.
If Mitigated
With proper access controls and monitoring, impact limited to isolated incidents with quick detection and remediation.
🎯 Exploit Status
Exploitation requires local access and knowledge of Python environment manipulation. No public exploit code identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.0.1
Vendor Advisory: https://checkmk.com/werk/16434
Restart Required: Yes
Instructions:
1. Download Robotmk 2.0.1 from official repository. 2. Stop Robotmk services. 3. Install the update. 4. Restart services. 5. Verify version shows 2.0.1 or higher.
🔧 Temporary Workarounds
Disable automated Python environment setup
allTurn off the vulnerable feature that allows shared holotree usage
robotmk config set python.auto_setup false
Restrict Python environment permissions
linuxSet proper file permissions on Python environment directories
chmod 750 /path/to/python/environments
chown root:robotmk /path/to/python/environments
🧯 If You Can't Patch
- Disable automated Python environment setup in Robotmk configuration
- Implement strict access controls and monitoring for local user activities
🔍 How to Verify
Check if Vulnerable:
Check Robotmk version with 'robotmk --version' and verify if automated Python environment setup is enabled in configuration
Check Version:
robotmk --version
Verify Fix Applied:
Confirm version is 2.0.1 or higher with 'robotmk --version' and verify Python environment permissions are properly restricted
