The remote Windows host is missing security update 5021234. It is, therefore, affected by multiple vulnerabilities

  • PowerShell Remote Code Execution Vulnerability (CVE-2022-41076)

  • Windows Subsystem for Linux (WSL2) Kernel Elevation of Privilege Vulnerability (CVE-2022-44689)

  • A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute unauthorized arbitrary commands. (CVE-2022-44676)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
