CVE-2022-41784
📋 TL;DR
This vulnerability in Intel's OFU software kernel driver allows authenticated local users to bypass access controls and escalate privileges. It affects systems running Intel OFU software before version 14.1.30. Attackers could gain SYSTEM/root-level access on compromised systems.
💻 Affected Systems
- Intel OFU (One-Boot Flash Update) software
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining kernel-level privileges, installing persistent malware, accessing all data, and disabling security controls.
Likely Case
Local privilege escalation allowing attackers to bypass application restrictions, install additional malware, or access protected system resources.
If Mitigated
Limited impact if proper network segmentation, least privilege principles, and endpoint protection are in place to contain lateral movement.
🎯 Exploit Status
Exploitation requires local authenticated access but the vulnerability is in a kernel driver, making successful exploitation relatively straightforward for attackers with initial access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 14.1.30 or later
Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00792.html
Restart Required: Yes
Instructions:
1. Download Intel OFU version 14.1.30 or later from Intel's website. 2. Run the installer with administrative privileges. 3. Restart the system to complete the update.
🔧 Temporary Workarounds
Remove Intel OFU software
windowsUninstall Intel OFU if not required for system operation
Control Panel > Programs > Uninstall a program > Select Intel OFU > Uninstall
Restrict driver loading
allImplement driver signature enforcement and restrict loading of unsigned drivers
🧯 If You Can't Patch
- Implement strict least privilege access controls to limit which users can log into affected systems
- Deploy application control/whitelisting solutions to prevent execution of unauthorized binaries
🔍 How to Verify
Check if Vulnerable:
Check Intel OFU version via Programs and Features (Windows) or package manager (Linux). If version is below 14.1.30, system is vulnerable.Check Version:
Windows: Check in Control Panel > Programs and Features. Linux: Check with package manager (rpm -qa | grep ofu or dpkg -l | grep ofu)Verify Fix Applied:
Verify Intel OFU version is 14.1.30 or higher after update installation.📡 Detection & Monitoring
Log Indicators:
- Unexpected driver loads (Intel OFU driver)
- Privilege escalation attempts
- Suspicious process creation with elevated privileges
Network Indicators:
- Lateral movement from previously compromised systems
- Unusual outbound connections from systems with Intel OFU
SIEM Query:
Process creation where parent process is Intel OFU related and child process has elevated privileges
