"The remote Windows host is missing security update 5009621.
It is, therefore, affected by multiple vulnerabilities:

  - A remote code execution vulnerability. An attacker can
    exploit this to bypass authentication and execute
    unauthorized arbitrary commands. (CVE-2022-21850, 
    CVE-2022-21851, CVE-2022-21893, CVE-2022-21928)

  - An information disclosure vulnerability. An attacker can
    exploit this to disclose potentially sensitive
    information. (CVE-2022-21880, CVE-2022-21904, 
    CVE-2022-21915)

  - A security feature bypass vulnerability exists. An
    attacker can exploit this and bypass the security
    feature and perform unauthorized actions compromising
    the integrity of the system/application.
    (CVE-2022-21900, CVE-2022-21905, CVE-2022-21913, 
    CVE-2022-21924)

  - A session spoofing vulnerability exists. An attacker can
    exploit this to perform actions with the privileges of
    another user. (CVE-2022-21836)

  - A denial of service (DoS) vulnerability. An attacker can
    exploit this issue to cause the affected component to
    deny system or application services. (CVE-2022-21843,
    CVE-2022-21848, CVE-2022-21883, CVE-2022-21889,
    CVE-2022-21890)

  - An elevation of privilege vulnerability. An attacker can
    exploit this to gain elevated privileges.
