The remote Windows host is missing security update 4598242.
It is, therefore, affected by multiple vulnerabilities :
An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive information. (CVE-2021-1637, CVE-2021-1645, CVE-2021-1656, CVE-2021-1663, CVE-2021-1670, CVE-2021-1672, CVE-2021-1676, CVE-2021-1696, CVE-2021-1699, CVE-2021-1708)
An memory corruption vulnerability exists. An attacker can exploit this to corrupt the memory and cause unexpected behaviors within the system/application.
(CVE-2021-1705)
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, CVE-2021-1710)
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, CVE-2021-1691)
An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.
(CVE-2021-1642, CVE-2021-1646, CVE-2021-1648, CVE-2021-1649, CVE-2021-1650, CVE-2021-1651, CVE-2021-1652, CVE-2021-1653, CVE-2021-1654, CVE-2021-1655, CVE-2021-1659, CVE-2021-1661, CVE-2021-1662, CVE-2021-1680, CVE-2021-1681, CVE-2021-1682, CVE-2021-1685, CVE-2021-1686, CVE-2021-1687, CVE-2021-1688, CVE-2021-1689, CVE-2021-1690, CVE-2021-1693, CVE-2021-1694, CVE-2021-1695, CVE-2021-1697, CVE-2021-1702, CVE-2021-1703, 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-2021-1638, CVE-2021-1669, CVE-2021-1674, CVE-2021-1678, CVE-2021-1683, CVE-2021-1684)
An memory corruption vulnerability exists. An attacker can exploit this to corrupt the memory and cause unexpected behaviors within the system/application (CVE-2021-1705)
