CVE-2024-22095
📋 TL;DR
This vulnerability allows a privileged user with local access to Intel Server D50DNP Family systems to escalate privileges through improper input validation in the PlatformVariableInitDxe UEFI firmware driver. Attackers could gain higher system privileges than intended. Only specific Intel server products with vulnerable UEFI firmware are affected.
💻 Affected Systems
- Intel Server D50DNP Family products
⚠️ 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.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining firmware-level control, persistence across reboots, and ability to bypass all operating system security controls.
Likely Case
Privileged user escalates to system/firmware administrator level, potentially installing persistent malware or accessing protected system resources.
If Mitigated
Limited impact if proper access controls restrict local privileged access and firmware integrity protections are enabled.
🎯 Exploit Status
Requires local privileged access and knowledge of UEFI exploitation techniques. No public exploit code known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Updated UEFI firmware from Intel
Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-01080.html
Restart Required: Yes
Instructions:
1. Check Intel advisory for affected firmware versions. 2. Download updated UEFI firmware from Intel support site. 3. Follow Intel's firmware update procedures for D50DNP systems. 4. Reboot system after update.
🔧 Temporary Workarounds
Restrict local privileged access
allLimit number of users with local administrative privileges to reduce attack surface
Enable firmware integrity protections
allEnable Secure Boot and other firmware security features if available
🧯 If You Can't Patch
- Implement strict access controls to limit local privileged users
- Monitor for unusual firmware access or modification attempts
🔍 How to Verify
Check if Vulnerable:
Check UEFI firmware version in system BIOS/UEFI settings or using manufacturer tools, then compare with Intel advisoryCheck Version:
System-specific: Use Intel Server Configuration Utility or check BIOS/UEFI settingsVerify Fix Applied:
Verify UEFI firmware version has been updated to patched version listed in Intel advisory📡 Detection & Monitoring
Log Indicators:
- Unexpected firmware access attempts
- Privilege escalation events
- UEFI/BIOS modification logs
Network Indicators:
- Not network exploitable - focus on local system monitoring
SIEM Query:
Search for: 'privilege escalation' AND ('UEFI' OR 'firmware' OR 'BIOS') AND source_user=privileged_user
