CVE-2023-22662

5.8 MEDIUM

📋 TL;DR

This vulnerability in UEFI firmware for certain Intel Server Board S2600BP products allows a privileged user with local access to trigger denial of service through improper input validation in the EpsdSrMgmtConfig component. It affects systems running vulnerable firmware versions on these specific server boards. The impact is limited to local attackers who already have elevated privileges on the system.

💻 Affected Systems

Products:
  • Intel Server Board S2600BP
Versions: Specific firmware versions as listed in Intel advisory
Operating Systems: Any OS running on affected hardware
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects systems with the specific Intel server boards mentioned. Requires local access and privileged user credentials.

⚠️ 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

Privileged attacker causes system crash or instability requiring physical intervention to restore functionality.

🟠

Likely Case

Malicious administrator or compromised privileged account disrupts server availability temporarily.

🟢

If Mitigated

Minimal impact with proper access controls and monitoring of privileged accounts.

🌐 Internet-Facing: LOW - Requires local access and privileged credentials.
🏢 Internal Only: MEDIUM - Internal privileged users could exploit, but requires specific hardware and elevated access.

🎯 Exploit Status

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

Exploitation requires privileged local access and knowledge of the vulnerable firmware component. No public exploits known at this time.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Firmware updates specified in Intel-SA-01080

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

Restart Required: Yes

Instructions:

1. Download firmware update from Intel support site. 2. Follow Intel's firmware update procedures for S2600BP server boards. 3. Apply update through UEFI/BIOS interface. 4. Reboot system to complete installation.

🔧 Temporary Workarounds

Restrict privileged access

all

Limit local administrative access to only trusted personnel

Monitor privileged account activity

all

Implement logging and alerting for privileged account actions

🧯 If You Can't Patch

  • Implement strict access controls to limit who has local administrative privileges
  • Monitor systems for unexpected reboots or instability that could indicate exploitation attempts

🔍 How to Verify

Check if Vulnerable:

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

Check 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 system reboots
  • Firmware/UEFI access logs showing privileged operations
  • System instability events

Network Indicators:

  • None - local attack only

SIEM Query:

search for 'system reboot' OR 'firmware' OR 'UEFI' events from privileged accounts on S2600BP systems
