CVE-2023-28397
📋 TL;DR
This vulnerability allows authenticated attackers with local access to potentially escalate privileges in systems using affected Intel Aptio V UEFI Firmware Integrator Tools. The improper access control could enable attackers to gain higher-level system privileges than intended. This affects systems where these specific Intel firmware tools are used.
💻 Affected Systems
- Intel Aptio V UEFI Firmware Integrator Tools
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining firmware-level control, potentially persisting across OS reinstalls and bypassing security controls.
Likely Case
Local privilege escalation allowing authenticated users to gain administrative or system-level access on affected systems.
If Mitigated
Limited impact if proper access controls and monitoring are in place, with attackers only able to escalate within their authorized scope.
🎯 Exploit Status
Requires authenticated local access and knowledge of the vulnerability. No public exploit code available as of advisory publication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to Intel SA-00908 for specific patched versions
Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00908.html
Restart Required: Yes
Instructions:
1. Check Intel SA-00908 advisory for affected versions. 2. Contact system/device manufacturer for firmware updates. 3. Apply firmware update following manufacturer instructions. 4. Reboot system to activate new firmware.
🔧 Temporary Workarounds
Restrict Local Access
allLimit physical and remote local access to systems with affected firmware
Implement Least Privilege
allEnsure users only have minimum necessary privileges to reduce impact of escalation
🧯 If You Can't Patch
- Isolate affected systems from critical networks and sensitive data
- Implement strict monitoring and logging of local access and privilege escalation attempts
🔍 How to Verify
Check if Vulnerable:
Check system firmware version and compare against Intel SA-00908 advisory. Contact system manufacturer for specific vulnerability assessment.
Check Version:
Windows: wmic bios get smbiosbiosversion
Linux: dmidecode -s bios-version
macOS: system_profiler SPHardwareDataType | grep "Boot ROM Version"
Verify Fix Applied:
Verify firmware version after update matches patched version specified in Intel advisory or manufacturer documentation.
