The remote Windows host is missing security update 4601366 or cumulative update 4601360. It is, therefore, affected by multiple vulnerabilities :

  • A denial of service (DoS) vulnerability. An attacker can exploit this issue to cause the affected component to deny system or application services. (CVE-2021-24080, CVE-2021-24086)

  • A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute unauthorized arbitrary commands. (CVE-2021-1722, CVE-2021-24074, CVE-2021-24077, CVE-2021-24078, CVE-2021-24088, CVE-2021-24094)

  • An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.
    (CVE-2021-1727, CVE-2021-24102, CVE-2021-24103)

  • An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive information. (CVE-2021-1734)
