Talos Rules 2021-06-04
This release adds and modifies rules in several categories.

This release provides coverage via SID 57720 for CVE-2021-21985, a remote code execution vulnerability in the vSphere Client’s Virtual SAN Health Check plug-in, which is enabled by default in vCenter Server. An attacker with network access to this service can exploit this vulnerability to gain remote code execution on the affected vCenter Server.

Talos has added a rule in the server-webapp rule sets to provide coverage for emerging threats from these technologies.
