CVE-2024-38307

7.7 HIGH

📋 TL;DR

This vulnerability in Intel AMT and Standard Manageability firmware allows authenticated users to cause denial of service through improper input validation. It affects systems with vulnerable Intel management firmware versions. Attackers with network access and authentication can disrupt management functionality.

💻 Affected Systems

Products:
  • Intel Active Management Technology (AMT)
  • Intel Standard Manageability
Versions: Specific vulnerable versions listed in Intel advisory INTEL-SA-01152
Operating Systems: All operating systems using affected Intel management firmware
Default Config Vulnerable: ⚠️ Yes
Notes: Requires Intel AMT or Standard Manageability to be enabled and configured. Systems without these features enabled are not vulnerable.

⚠️ 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).

  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

Complete disruption of Intel AMT/Standard Manageability services, preventing remote management of affected systems and potentially requiring physical access to restore functionality.

🟠

Likely Case

Temporary denial of service affecting remote management capabilities, requiring system reboot or firmware update to restore normal operation.

🟢

If Mitigated

Minimal impact with proper network segmentation and authentication controls limiting access to management interfaces.

🌐 Internet-Facing: MEDIUM - While authentication is required, exposed management interfaces could be targeted by attackers with stolen credentials.
🏢 Internal Only: HIGH - Internal attackers or compromised accounts could exploit this to disrupt management infrastructure across the organization.

🎯 Exploit Status

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

Requires authenticated access to the management interface. No public exploit code available at this time.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Firmware updates provided by Intel through OEM partners

Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01152.html

Restart Required: No

Instructions:

1. Check Intel advisory for affected products. 2. Contact your system/OEM vendor for firmware updates. 3. Apply firmware updates following vendor instructions. 4. Verify update completion through management console.

🔧 Temporary Workarounds

Network Segmentation

all

Restrict access to Intel AMT/Standard Manageability interfaces to authorized management networks only

Authentication Hardening

all

Implement strong authentication mechanisms and regularly rotate credentials for management interfaces

🧯 If You Can't Patch

  • Disable Intel AMT/Standard Manageability if not required for operations
  • Implement strict network access controls to limit exposure of management interfaces

🔍 How to Verify

Check if Vulnerable:

Check Intel Management Engine firmware version against vulnerable versions listed in INTEL-SA-01152 advisory

Check Version:

On Windows: wmic bios get smbiosbiosversion; On Linux: dmidecode -t bios

Verify Fix Applied:

Verify firmware version has been updated to patched version through Intel Management Engine BIOS Extension (MEBX) or system management tools

📡 Detection & Monitoring

Log Indicators:

  • Unusual authentication attempts to management interfaces
  • Multiple failed connection attempts followed by service disruption

Network Indicators:

  • Unusual traffic patterns to Intel AMT ports (default 16992-16995, 623)
  • Sudden drops in management service availability

SIEM Query:

source="management_interface" AND (event_type="authentication_failure" OR event_type="service_stop")
