CVE-2022-36396
📋 TL;DR
This vulnerability allows a privileged user with local access to bypass access controls in Intel Aptio V UEFI Firmware Integrator Tools, potentially enabling privilege escalation. It affects systems using vulnerable versions of these firmware development tools, primarily impacting developers and organizations building UEFI firmware.
💻 Affected Systems
- Intel Aptio V UEFI Firmware Integrator Tools
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker with local privileged access could modify UEFI firmware components to establish persistent backdoors, bypass secure boot, or gain full system control.
Likely Case
A malicious insider or compromised administrator account could escalate privileges to modify firmware settings or inject malicious code.
If Mitigated
With proper access controls and least privilege principles, the attack surface is limited to authorized firmware developers only.
🎯 Exploit Status
Exploitation requires local privileged access to the system where the vulnerable tools are installed.

✅ Official Fix
Patch Version: iDmiEdit-Linux-5.27.06.0017 or later
Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00908.html
Restart Required: No
Instructions:
1. Download the updated version from Intel's official channels. 2. Uninstall the vulnerable version. 3. Install the patched version. 4. Verify the installation.
🔧 Temporary Workarounds
Restrict tool access
linuxLimit access to the vulnerable tools to only authorized firmware developers using strict access controls.
Use appropriate OS-level access controls (e.g., chmod, chown on Linux)
Isolate development environment
allRun the vulnerable tools in isolated development environments with no production access.
🧯 If You Can't Patch
- Remove the vulnerable tools from systems where they are not absolutely required
- Implement strict access controls and audit logging for all systems with the vulnerable tools installed
