CVE-2024-39813

6.7 MEDIUM

📋 TL;DR

This vulnerability in EPCT software allows authenticated local users to escalate privileges by manipulating the search path. It affects systems running EPCT software versions before 1.42.8.0 where users have local access.

💻 Affected Systems

Products:
  • EPCT software
Versions: All versions before 1.42.8.0
Operating Systems: Windows, Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Requires local authenticated access to the system where EPCT software is installed.

⚠️ 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

An authenticated attacker gains full administrative/root privileges on the system, potentially compromising the entire host.

🟠

Likely Case

Local users with standard privileges can elevate to administrator/system-level access to install malware, modify system configurations, or access sensitive data.

🟢

If Mitigated

With proper access controls and monitoring, impact is limited to isolated systems with minimal lateral movement potential.

🌐 Internet-Facing: LOW - This requires local authenticated access, not directly exploitable over the internet.
🏢 Internal Only: HIGH - Internal users with local access can exploit this to gain elevated privileges on affected systems.

🎯 Exploit Status

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

Exploitation involves manipulating DLL/executable search paths, which is a well-understood technique for local privilege escalation.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 1.42.8.0

Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01227.html

Restart Required: Yes

Instructions:

1. Download EPCT version 1.42.8.0 or later from Intel's official website. 2. Run the installer with administrative privileges. 3. Follow on-screen instructions to complete installation. 4. Restart the system as prompted.

🔧 Temporary Workarounds

Restrict local user permissions

all

Limit standard user accounts' ability to write to directories in the system PATH or EPCT installation directories.

Enable Windows Defender Application Control

windows

Use application control policies to restrict execution of unauthorized binaries.

🧯 If You Can't Patch

  • Implement strict least-privilege access controls for local users
  • Monitor for suspicious process creation and privilege escalation attempts

🔍 How to Verify

Check if Vulnerable:

Check EPCT software version via: Windows: Check Programs and Features or run 'wmic product where name="EPCT" get version'. Linux: Check package version or run EPCT with --version flag.

Check Version:

Windows: wmic product where name="EPCT" get version. Linux: epct --version or check package manager.

Verify Fix Applied:

Confirm version is 1.42.8.0 or higher using the same version check commands.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected process execution with elevated privileges
  • DLL loading from unusual locations
  • EPCT process spawning with different user context

Network Indicators:

  • Not applicable - local exploitation only

SIEM Query:

Process creation where parent_process contains "epct" and integrity_level changes OR user changes
