CVE-2020-8714
📋 TL;DR
This vulnerability allows an authenticated user with local access to Intel server hardware to potentially escalate privileges due to improper authentication in the firmware. It affects Intel Server Boards, Server Systems, and Compute Modules running firmware versions before 1.59.
💻 Affected Systems
- Intel Server Boards
- Intel Server Systems
- Intel Compute Modules
📦 What is this software?
Compute Module Hns2600bp Firmware by Intel
Compute Module Hns2600kp Firmware by Intel
Compute Module Hns2600tp Firmware by Intel
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker gains administrative control over the server hardware, potentially compromising the entire system and any hosted services.
Likely Case
An insider or compromised account with local access escalates privileges to perform unauthorized firmware modifications or access restricted hardware functions.
If Mitigated
With strict access controls and monitoring, impact is limited to authorized personnel only, reducing escalation opportunities.
🎯 Exploit Status
Requires authenticated access to the server hardware management interface; exploitation details not publicly documented.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version 1.59 or later
Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00384.html
Restart Required: Yes
Instructions:
1. Download firmware update 1.59 or later from Intel support site. 2. Apply firmware update through server management interface. 3. Reboot the server to complete installation.
🔧 Temporary Workarounds
Restrict Management Interface Access
allLimit network access to server management interfaces to authorized administrative networks only.
Configure firewall rules to restrict access to BMC/IPMI management ports (default 623/664)
Enforce Strong Authentication
allImplement multi-factor authentication and strong password policies for server management interfaces.
Configure BMC/IPMI authentication settings to require strong passwords and MFA if supported
🧯 If You Can't Patch
- Isolate server management interfaces on separate VLANs with strict access controls
- Implement comprehensive logging and monitoring of all management interface access attempts
🔍 How to Verify
Check if Vulnerable:
Check firmware version in server management interface (BMC/IPMI) or via vendor-specific commands.Check Version:
ipmitool mc info (Linux) or vendor-specific management software commandsVerify Fix Applied:
Confirm firmware version is 1.59 or later in server management interface.📡 Detection & Monitoring
Log Indicators:
- Unusual authentication attempts on server management interfaces
- Firmware modification logs
- Privilege escalation attempts in system logs
Network Indicators:
- Unexpected connections to server management ports (623/664)
- Traffic patterns indicating firmware manipulation
