Steps to Address CVE-2022-0001
Apply the Registry Fix for Windows Devices (Intel Processors):
To mitigate CVE-2022-0001, apply the following registry updates:
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 0x00800000 /f reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 0x00000003 /f- This fix is recommended by Microsoft to address the vulnerability.
- Ensure the fix is applied to all affected devices.
Rescan Devices in CYRISMA:
- Once the registry fix is applied, rescan the devices using the CYRISMA platform to check if the vulnerability is cleared.
- Confirm that the registry changes are effective in mitigating the CVE.
Understanding CYRISMA’s Detection Parameters:
- CYRISMA detects CVE-2022-0001 primarily through processor identifiers.
- While the registry fix resolves the issue, CYRISMA may not validate the fix if it does not align with the parameters used in the scan.
Use Manual Mitigation as a Backup:
- If CYRISMA does not automatically clear the vulnerability despite applying the registry fix, consider marking the CVE as mitigated manually in the CYRISMA dashboard.
- Document the steps taken (e.g., registry fix) and reference Microsoft’s official guidance: Microsoft Security Update Guide.
Common Challenges and Solutions
Challenge: CYRISMA still flags CVE-2022-0001 as unresolved after applying the registry fix.
Solution: Verify that the registry keys were applied correctly and ensure the latest Cyrisma update is in use for accurate scanning.
Challenge: Discrepancy between CYRISMA’s detection and Microsoft’s recommendations.
Solution: Use manual mitigation in CYRISMA to mark the CVE resolved, noting the applied fix in your documentation.
Summary
To resolve CVE-2022-0001:
- Apply the recommended registry fix.
- Rescan affected devices in CYRISMA.
- Use manual mitigation if necessary, with documented evidence of the fix.
