The remote Windows host is missing security update 4537776.
It is, therefore, affected by multiple vulnerabilities :

  • A remote code execution vulnerability exists in the Windows Remote Desktop Client when a user connects to a malicious server. An attacker who successfully exploited this vulnerability could execute arbitrary code on the computer of the connecting client. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
    (CVE-2020-0681, CVE-2020-0734, CVE-2020-0817)

  • A memory corruption vulnerability exists when Windows Media Foundation improperly handles objects in memory.
    An attacker who successfully exploited the vulnerability could install programs; view, change, or delete data; or create new accounts with full user rights. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit a malicious webpage. The security update addresses the vulnerability by correcting how Windows Media Foundation handles objects in memory. (CVE-2020-0738)

    way that an attacker could execute arbitrary code in the 
    context of the current user. An attacker who successfully 
    exploited the vulnerability could gain the same user 
    rights as the current user. If the current user is logged 
    on with administrative user rights, an attacker who 
    successfully exploited the vulnerability could take 
    control of an affected system. An attacker could then 
    install programs; view, change, or delete data; or create 
    new accounts with full user rights. (CVE-2020-0767)

  - An elevation of privilege vulnerability exists in the
    way that the sysmain.dll handles objects in memory. An
    attacker who successfully exploited the vulnerability
    could execute code with elevated permissions. To exploit
    the vulnerability, a locally authenticated attacker
    could run a specially crafted application. The security
    update addresses the vulnerability by ensuring the
    sysmain.dll properly handles objects in memory.
