CVE-2024-39934

7.8 HIGH

📋 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

Products:
  • Robotmk
Versions: All versions before 2.0.1
Operating Systems: Windows, Linux
Default Config Vulnerable: ✅ No
Notes: Only vulnerable when automated Python environment setup is enabled. The 'shared holotree usage' feature must be active.

⚠️ 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).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ 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.

🌐 Internet-Facing: LOW - This is a local privilege escalation requiring local access to the system.
🏢 Internal Only: HIGH - Any local user on affected systems can potentially gain SYSTEM privileges.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

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

all

Turn off the vulnerable feature that allows shared holotree usage

robotmk config set python.auto_setup false

Restrict Python environment permissions

linux

Set 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

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized modifications to Python environment files
  • Unexpected privilege escalation events
  • Suspicious process creation with SYSTEM privileges

Network Indicators:

  • Unusual outbound connections from Robotmk processes
  • Lateral movement attempts from affected systems

SIEM Query:

Process Creation where Parent Process contains 'robotmk' AND Integrity Level changes to 'System'
