Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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.

  - 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)
