Security Updates for Exchange (March 2022)

high Nessus Plugin ID 158786

Synopsis

The Microsoft Exchange Server installed on the remote host is affected by multiple vulnerabilities.

Description

The Microsoft Exchange Server installed on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities including the following:

- A remote code execution vulnerability exists in Exchange. An authenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands (CVE-2022-23277).

- An information disclosure vulnerability exists in Exchange. An authenticated, remote attacker can exploit this to disclose the contents of files on the exchange server (CVE-2022-24463).

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Microsoft has released KB5012698 and KB5010324 to address this issue.
