CVE-2025-24308
📋 TL;DR
This vulnerability allows a privileged user with local access to Intel Server D50DNP and M50FCP systems to potentially escalate privileges through improper input validation in the UEFI firmware error handler. The flaw could enable attackers to gain higher system privileges than intended. Only users with existing local privileged access to these specific Intel server platforms are affected.
💻 Affected Systems
- Intel Server D50DNP
- Intel Server M50FCP
⚠️ 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
An attacker with existing local privileged access could gain full system control, potentially compromising the entire server including firmware-level persistence.
Likely Case
A malicious insider or compromised privileged account could escalate privileges to gain unauthorized access to sensitive system resources.
If Mitigated
With proper access controls and monitoring, the impact is limited to authorized privileged users who would need to intentionally exploit the vulnerability.
🎯 Exploit Status
Exploitation requires existing privileged access and knowledge of UEFI firmware internals.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Intel advisory for specific firmware versions
Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01269.html
Restart Required: Yes
Instructions:
1. Download updated firmware from Intel support site. 2. Follow Intel's firmware update procedures for D50DNP/M50FCP servers. 3. Apply firmware update through UEFI/BIOS interface. 4. Reboot server to complete installation.
🔧 Temporary Workarounds
Restrict physical and privileged access
allLimit physical access to servers and implement strict privileged access management
🧯 If You Can't Patch
- Implement strict privileged access controls and monitoring
- Isolate affected servers in secure network segments
🔍 How to Verify
Check if Vulnerable:
Check UEFI firmware version in BIOS/UEFI setup or using Intel's system identification toolsCheck Version:
dmidecode -t bios (Linux) or wmic bios get smbiosbiosversion (Windows)Verify Fix Applied:
Verify firmware version matches patched version from Intel advisory after update📡 Detection & Monitoring
Log Indicators:
- Unexpected firmware access attempts
- Privilege escalation patterns in system logs
Network Indicators:
- None - this is a local privilege escalation
