The remote Windows host is missing security update 5006672.
It is, therefore, affected by multiple vulnerabilities:
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-2021-40456, CVE-2021-40460, CVE-2021-41337, CVE-2021-41338)
A denial of service (DoS) vulnerability. An attacker can exploit this issue to cause the affected component to deny system or application services. (CVE-2021-36953, CVE-2021-40463)
A session spoofing vulnerability exists. An attacker can exploit this to perform actions with the privileges of another user. (CVE-2021-36970, CVE-2021-40455, CVE-2021-41361)
A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute unauthorized arbitrary commands. (CVE-2021-40461, CVE-2021-40462, CVE-2021-40465, CVE-2021-40469, CVE-2021-41330, CVE-2021-41331, CVE-2021-41340, CVE-2021-41342)
An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.
(CVE-2021-26441, CVE-2021-26442, CVE-2021-40443, CVE-2021-40449, CVE-2021-40450, CVE-2021-40464, CVE-2021-40466, CVE-2021-40467, CVE-2021-40470, CVE-2021-40476, CVE-2021-40477, CVE-2021-40478, CVE-2021-40488, CVE-2021-40489, CVE-2021-41335, CVE-2021-41345, CVE-2021-41347)
An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive information. (CVE-2021-38662, CVE-2021-38663, CVE-2021-40454, CVE-2021-40475, CVE-2021-41332, CVE-2021-41343)
