CVE-2024-22382

7.5 HIGH

📋 TL;DR

This vulnerability allows a privileged user to escalate privileges via local access due to improper input validation in the PprRequestLog module of UEFI firmware on specific Intel server products. It affects Intel(R) Server D50DNP Family products with vulnerable UEFI firmware versions. Attackers with existing local access could gain higher system privileges.

💻 Affected Systems

Products:
  • Intel(R) Server D50DNP Family products
Versions: Specific UEFI firmware versions before the patch (exact versions not specified in advisory)
Operating Systems: Any OS running on affected hardware
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects systems with vulnerable UEFI firmware versions. Requires local privileged access to exploit.

⚠️ 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

A privileged attacker could gain full system control, potentially compromising the entire server, accessing sensitive data, or installing persistent malware in firmware.

🟠

Likely Case

A malicious insider or compromised account could escalate privileges to gain unauthorized access to system resources or bypass security controls.

🟢

If Mitigated

With proper access controls and monitoring, impact is limited to authorized users who already have some system access.

🌐 Internet-Facing: LOW - Requires local access, not directly exploitable over network.
🏢 Internal Only: HIGH - Local privileged users can exploit this for privilege escalation within internal networks.

🎯 Exploit Status

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

Requires local privileged access and knowledge of UEFI firmware exploitation. No public exploit code known.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: UEFI firmware update specified in Intel advisory

Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-01080.html

Restart Required: Yes

Instructions:

1. Check current UEFI firmware version. 2. Download updated firmware from Intel support site. 3. Follow Intel's firmware update procedures for D50DNP servers. 4. Reboot system to apply firmware update.

🔧 Temporary Workarounds

Restrict local privileged access

all

Limit number of users with local administrative privileges to reduce attack surface

Implement strict access controls

all

Enforce principle of least privilege and monitor privileged user activities

🧯 If You Can't Patch

  • Implement strict monitoring of privileged user activities and local access
  • Isolate affected servers in secure network segments with limited access

🔍 How to Verify

Check if Vulnerable:

Check UEFI firmware version in BIOS/UEFI settings or using Intel's system identification tools

Check Version:

System-specific commands vary; typically accessed via BIOS/UEFI interface or vendor management tools

Verify Fix Applied:

Verify UEFI firmware version matches patched version from Intel advisory after update

📡 Detection & Monitoring

Log Indicators:

  • Unusual privileged user activity
  • Unexpected firmware access attempts
  • Privilege escalation events

Network Indicators:

  • Local network traffic from server indicating compromise

SIEM Query:

Search for privilege escalation events or unusual local user activity on affected servers
