high Nessus Plugin ID 160941

Synopsis

The Windows app installed on the remote host is affected by multiple vulnerabilities.

Description

The Windows Remote Desktop client for Windows installed on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:

- An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive information. (CVE-2022-22015, CVE-2022-26940)

- A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute unauthorized arbitrary commands. (CVE-2022-22017)

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

Solution

Upgrade to client version 1.2.3130 or later.
