Description

This module chains two vulnerabilities on Microsoft Exchange Server
that, when combined, allow an authenticated attacker to interact with
the Exchange Powershell backend (CVE-2022-41040), where a
deserialization flaw can be leveraged to obtain code execution
(CVE-2022-41082). This exploit only support Exchange Server 2019.

These vulnerabilities were patched in November 2022.
