Internet Explorer Zero-Day Vulnerability Audit

Audit Windows Machines Vulnerable to IE Zero-Day

Microsoft released an emergency update for a critical Internet Explorer zero-day vulnerability (CVE-2019-1367). This scripting engine memory corruption vulnerability could allow attackers to gain access to machines using the security context of the logged-in user. Therefore it is especially important to make sure that machines which often times use admin credentials are updated as soon as possible. You can find more information in our IE zero-day vulnerability blog post.

To fix the issue, Microsoft has released new updates. The audit below will give you a clear overview of the patch status of all Windows machines which have received a patch. Monitor exactly which machines have been updated.
