Senserva AI Opinion for CVE-2016-7200

A companion to the other Chakra engine flaw of the same era, this Microsoft Edge memory corruption also delivers remote code execution from a crafted page and is confirmed exploited per CISA KEV. Attackers reach it simply by luring a user to a hostile site. Only pre-Chromium Edge carries the vulnerable engine.

Do this: Remove or update any remaining legacy Edge installs; the Chakra engine has no place on a managed endpoint.
