The remote Windows host is missing security update 5012666 or cumulative update 5012650. 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-2022-26812, CVE-2022-26919,CVE-2022-26809,CVE-2022-26918,CVE-2022-26813, CVE-2022-26821,CVE-2022-26819,CVE-2022-26815,CVE-2022-26916, CVE-2022-26822,CVE-2022-26917,CVE-2022-26829,CVE-2022-26820, CVE-2022-24541,CVE-2022-24492,CVE-2022-24536,CVE-2022-24534, CVE-2022-24485,CVE-2022-24533,CVE-2022-26903,CVE-2022-24528, CVE-2022-21983,CVE-2022-24500)

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

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

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

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