CVE-2024-39805
📋 TL;DR
This vulnerability in Intel DSA software allows authenticated local users to potentially escalate privileges due to insufficient data authenticity verification. It affects systems running vulnerable versions of Intel DSA software before 23.4.39. Attackers could gain elevated system privileges if they already have authenticated access to the system.
💻 Affected Systems
- Intel Driver & Support Assistant (DSA)
⚠️ 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
An authenticated attacker gains full administrative/root privileges on the system, enabling complete system compromise, data theft, and persistence establishment.
Likely Case
An authenticated user with standard privileges escalates to administrative privileges, potentially installing malware, accessing sensitive data, or modifying system configurations.
If Mitigated
With proper access controls and least privilege principles, the impact is limited as only authenticated users can exploit it, and they would need to bypass additional security layers.
🎯 Exploit Status
Exploitation requires authenticated local access and knowledge of the vulnerability. No public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 23.4.39 or later
Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01030.html
Restart Required: No
Instructions:
1. Open Intel DSA application. 2. Check for updates in the application interface. 3. Install update to version 23.4.39 or later. 4. Alternatively, download and install the latest version from Intel's official website.
🔧 Temporary Workarounds
Disable Intel DSA Service
WindowsTemporarily disable the Intel DSA service to prevent exploitation while awaiting patch deployment.
sc stop "Intel(R) Driver & Support Assistant"
sc config "Intel(R) Driver & Support Assistant" start= disabled
Remove Local User Access
allRestrict local user access to systems running vulnerable Intel DSA versions.
🧯 If You Can't Patch
- Implement strict least privilege access controls to limit authenticated user capabilities
- Monitor for privilege escalation attempts and unusual administrative activity
🔍 How to Verify
Check if Vulnerable:
Check Intel DSA version in the application interface or via installed programs list. Versions below 23.4.39 are vulnerable.Check Version:
On Windows: Check 'Apps & features' in Settings or run 'wmic product get name,version' | findstr /i "Intel Driver"Verify Fix Applied:
Confirm Intel DSA version is 23.4.39 or later in the application interface or installed programs.📡 Detection & Monitoring
Log Indicators:
- Unusual privilege escalation events in Windows Event Logs (Security log Event ID 4672, 4688)
- Intel DSA service errors or unexpected restarts
- Process creation by Intel DSA with elevated privileges
Network Indicators:
- Local system activity only - no network indicators for this local privilege escalation
SIEM Query:
EventID=4672 OR EventID=4688 | where ProcessName contains "Intel" OR ParentProcessName contains "Intel" | where NewIntegrityLevel="High" OR NewIntegrityLevel="System"
