The remote Windows host is missing security update 5007192.
It is, therefore, affected by multiple vulnerabilities:

  • An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive information. (CVE-2021-38631, CVE-2021-38665, CVE-2021-41371)

  • A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute unauthorized arbitrary commands. (CVE-2021-38666, CVE-2021-42275, CVE-2021-42276, CVE-2021-42279)

  • A denial of service (DoS) vulnerability. An attacker can exploit this issue to cause the affected component to deny system or application services. (CVE-2021-41356, CVE-2021-42274, CVE-2021-42284)

  • An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.
    (CVE-2021-36957, CVE-2021-41366, CVE-2021-41367, CVE-2021-41370, CVE-2021-41377, CVE-2021-41379, CVE-2021-42277, CVE-2021-42278, CVE-2021-42280, CVE-2021-42282, CVE-2021-42283, CVE-2021-42285, CVE-2021-42287, CVE-2021-42291)
