CVE-2023-42668

6.7 MEDIUM

📋 TL;DR

This vulnerability allows authenticated users with local access to Intel Server Boards to escalate privileges due to incorrect default permissions in onboard video driver software. It affects systems running Intel Server Boards based on Intel 62X Chipset with vulnerable driver versions. Attackers could gain elevated system access.

💻 Affected Systems

Products:
  • Intel Server Boards based on Intel 62X Chipset
Versions: Onboard video driver software versions before 1.14
Operating Systems: Any OS using the affected driver
Default Config Vulnerable: ⚠️ Yes
Notes: Requires local authenticated access to the physical server or console.

⚠️ Risk & Real-World Impact

🔴

Worst Case

An authenticated attacker gains full administrative control over the server, potentially compromising all data and services.

🟠

Likely Case

An insider or compromised account escalates privileges to install malware, exfiltrate data, or maintain persistence.

🟢

If Mitigated

With proper access controls and monitoring, impact is limited to isolated systems with no critical data exposure.

🌐 Internet-Facing: LOW - Requires local authenticated access, not remotely exploitable.
🏢 Internal Only: MEDIUM - Insider threats or compromised accounts could exploit this for privilege escalation within the network.

🎯 Exploit Status

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

Requires authenticated local access and knowledge of driver manipulation.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Version 1.14 or later

Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00962.html

Restart Required: Yes

Instructions:

1. Download updated driver from Intel support site. 2. Install driver version 1.14 or later. 3. Reboot the server.

🔧 Temporary Workarounds

Restrict local access

all

Limit physical and console access to authorized personnel only.

Monitor driver permissions

all

Regularly audit file permissions on driver components.

🧯 If You Can't Patch

  • Implement strict access controls to limit who can log into affected servers locally.
  • Monitor for unusual privilege escalation attempts and driver modification activities.

🔍 How to Verify

Check if Vulnerable:

Check driver version in device manager or system information. If version is below 1.14, system is vulnerable.

Check Version:

On Windows: wmic path win32_pnpentity get caption,driverVersion | findstr /i "Intel Video"

Verify Fix Applied:

Confirm driver version is 1.14 or higher after update.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected driver installation/modification events
  • Privilege escalation attempts in security logs

Network Indicators:

  • None - local exploit only

SIEM Query:

EventID=4688 AND (ProcessName contains "driver" OR CommandLine contains "video")
