The remote Windows host is missing security update 5012639 or cumulative update 5012670. It is, therefore, affected by multiple vulnerabilities:

  • An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.
    (CVE-2022-24474, CVE-2022-24481, CVE-2022-24494, CVE-2022-24499, CVE-2022-24521, CVE-2022-24527, CVE-2022-24530, CVE-2022-24540, CVE-2022-24542, CVE-2022-24544, CVE-2022-24547, CVE-2022-24550, CVE-2022-26786, CVE-2022-26787, CVE-2022-26788, CVE-2022-26790, CVE-2022-26792, CVE-2022-26794, CVE-2022-26796, CVE-2022-26797, CVE-2022-26798, CVE-2022-26801, CVE-2022-26802, CVE-2022-26803, CVE-2022-26807, CVE-2022-26808, CVE-2022-26810, CVE-2022-26827, CVE-2022-26904)

  • A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute unauthorized arbitrary commands. (CVE-2022-21983, CVE-2022-22008, CVE-2022-24485, CVE-2022-24491, CVE-2022-24492, CVE-2022-24500, CVE-2022-24528, CVE-2022-24533, CVE-2022-24534, CVE-2022-24536, CVE-2022-24541, CVE-2022-26809, CVE-2022-26812, CVE-2022-26813, CVE-2022-26814, CVE-2022-26815, CVE-2022-26817, CVE-2022-26818, CVE-2022-26819, CVE-2022-26820, CVE-2022-26821, CVE-2022-26822, CVE-2022-26829, CVE-2022-26903, CVE-2022-26916, CVE-2022-26917, CVE-2022-26918, CVE-2022-26919)

  • An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive information. (CVE-2022-24483, CVE-2022-24493, CVE-2022-24498)

  • A denial of service (DoS) vulnerability. An attacker can exploit this issue to cause the affected component to deny system or application services. (CVE-2022-24484, CVE-2022-24538, CVE-2022-26784, CVE-2022-26831, CVE-2022-26915)
