CVE-2024-31201
📋 TL;DR
This vulnerability involves an unquoted search path in the ThermoscanIP_Scrutation service, allowing attackers to execute arbitrary code by placing malicious executables in directories with higher permissions. It affects systems running vulnerable versions of the ThermoscanIP software where the service path is improperly configured. Local attackers could exploit this to escalate privileges on compromised machines.
💻 Affected Systems
- ThermoscanIP_Scrutation service
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise via privilege escalation to SYSTEM/root, enabling complete control over the affected machine.
Likely Case
Local privilege escalation allowing attackers to gain higher privileges than their initial access level.
If Mitigated
Limited impact with proper file permissions and service hardening preventing unauthorized file placement.
🎯 Exploit Status
Exploitation requires local access and ability to write to directories in the search path before the legitimate executable.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: https://www.nozominetworks.com/labs/vulnerability-advisories-cve-2024-31201
Restart Required: Yes
Instructions:
1. Review vendor advisory for specific patch details. 2. Apply any available updates. 3. Restart affected services/systems.
🔧 Temporary Workarounds
Quote Service Path
windowsModify the service configuration to use quoted paths in the executable path.
sc config "ThermoscanIP_Scrutation" binPath="\"C:\Path\To\Service.exe\"" arguments
Restrict Directory Permissions
windowsRemove write permissions from directories in the service search path.
icacls "C:\Program Files" /deny Everyone:(OI)(CI)W
🧯 If You Can't Patch
- Implement strict file system permissions on directories in the service path
- Monitor for unauthorized file creation in system directories
🔍 How to Verify
Check if Vulnerable:
Check service configuration: sc qc "ThermoscanIP_Scrutation" and verify if BINARY_PATH_NAME contains unquoted paths with spaces.Check Version:
Check service properties or consult vendor documentation for version information.Verify Fix Applied:
Confirm service path is properly quoted and directory permissions are restricted.📡 Detection & Monitoring
