CVE-2023-49615
📋 TL;DR
This vulnerability allows a privileged user with local access to potentially escalate privileges through improper input validation in Intel System Security Report and System Resources Defense firmware. It affects systems running vulnerable Intel firmware versions. Attackers could gain higher system privileges than intended.
💻 Affected Systems
- Intel System Security Report firmware
- Intel System Resources Defense firmware
⚠️ 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).

⚠️ Risk & Real-World Impact
Worst Case
A privileged attacker could gain full system control, compromise firmware integrity, and establish persistent access that survives OS reinstallation.
Likely Case
Privileged users could elevate their access to higher system levels, potentially accessing sensitive data or modifying system configurations.
If Mitigated
With proper access controls and monitoring, impact is limited to authorized users attempting privilege escalation, which can be detected and prevented.
🎯 Exploit Status
Requires local access and privileged credentials. Exploitation involves manipulating firmware input validation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Firmware updates specified in Intel advisory
Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01203.html
Restart Required: Yes
Instructions:
1. Check Intel advisory for affected products. 2. Download firmware updates from Intel support site. 3. Apply firmware updates following manufacturer instructions. 4. Reboot system to activate new firmware.
🔧 Temporary Workarounds
Restrict local privileged access
allLimit number of users with local administrative privileges to reduce attack surface
Implement privilege separation
allUse least privilege principles and separate administrative functions
🧯 If You Can't Patch
- Implement strict access controls and monitor privileged user activities
- Segment affected systems and limit lateral movement capabilities
🔍 How to Verify
Check if Vulnerable:
Check firmware version against Intel advisory. Use manufacturer tools like Intel System Support Utility.Check Version:
Manufacturer-specific commands vary by system. Check BIOS/UEFI settings or use 'wmic bios get smbiosbiosversion' on Windows, 'dmidecode -t bios' on Linux.Verify Fix Applied:
Verify firmware version after update matches patched version in Intel advisory.📡 Detection & Monitoring
Log Indicators:
- Unusual firmware access attempts
- Privilege escalation attempts
- Firmware modification logs
Network Indicators:
- Not applicable - local access required
SIEM Query:
Search for firmware access events, privilege escalation patterns, or unauthorized administrative actions on affected systems.
