The remote Windows host is missing security update 4598289 or cumulative update 4598279. 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-2021-1657, CVE-2021-1658, CVE-2021-1660, CVE-2021-1664, CVE-2021-1665, CVE-2021-1666, CVE-2021-1667, CVE-2021-1668, CVE-2021-1671, CVE-2021-1673, CVE-2021-1700, CVE-2021-1701)
An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.
(CVE-2021-1649, CVE-2021-1652, CVE-2021-1653, CVE-2021-1654, CVE-2021-1655, CVE-2021-1659, CVE-2021-1661, CVE-2021-1688, CVE-2021-1693, CVE-2021-1694, CVE-2021-1695, CVE-2021-1702, CVE-2021-1704, CVE-2021-1706, CVE-2021-1709)
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-2021-1674, CVE-2021-1678)
An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive information. (CVE-2021-1656, CVE-2021-1676, CVE-2021-1696, CVE-2021-1699, CVE-2021-1708)
A denial of service (DoS) vulnerability. An attacker can exploit this issue to cause the affected component to deny system or application services. (CVE-2021-1679)
