Synopsis
The remote Windows host is affected by multiple vulnerabilities.
Description
The remote Windows host is missing security update 4537762. 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)
- An information disclosure vulnerability exists in the way that affected Microsoft browsers handle cross-origin requests. An attacker who successfully exploited this vulnerability could determine the origin of all of the web pages in the affected browser. (CVE-2020-0706)
- An information disclosure vulnerability exists when DirectX improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. An authenticated attacker could exploit this vulnerability by running a specially crafted application. The update addresses the vulnerability by correcting how DirectX handles objects in memory. (CVE-2020-0714)
- An information disclosure vulnerability exists in the Windows Common Log File System (CLFS) driver when it fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could potentially read data that was not intended to be disclosed. Note that this vulnerability would not allow an attacker to execute code or to elevate their user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system. (CVE-2020-0658)
- An elevation of privilege vulnerability exists when Microsoft Edge does not properly enforce cross-domain policies, which could allow an attacker to access information from one domain and inject it into another domain. (CVE-2020-0663)

An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2020-0691)
- An elevation of privilege vulnerability exists in Active Directory Forest trusts due to a default setting that lets an attacker in the trusting forest request delegation of a TGT for an identity from the trusted forest. (CVE-2020-0665)
- An elevation of privilege vulnerability exists in Windows Error Reporting (WER) when WER handles and executes files. The vulnerability could allow elevation of privilege if an attacker can successfully exploit it. An attacker who successfully exploited the vulnerability could gain greater access to sensitive information and system functionality. (CVE-2020-0753, CVE-2020-0754)

"The remote Windows host is missing security update 4537762.
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)
- An information disclosure vulnerability exists in the
way that affected Microsoft browsers handle cross-origin
requests. An attacker who successfully exploited this
vulnerability could determine the origin of all of the
web pages in the affected browser. (CVE-2020-0706)
- An information disclosure vulnerability exists when
DirectX improperly handles objects in memory. An
attacker who successfully exploited this vulnerability
could obtain information to further compromise the users
system. An authenticated attacker could exploit this
vulnerability by running a specially crafted
application. The update addresses the vulnerability by
correcting how DirectX handles objects in memory.
(CVE-2020-0714)
- An information disclosure vulnerability exists in the
Windows Common Log File System (CLFS) driver when it
fails to properly handle objects in memory. An attacker
who successfully exploited this vulnerability could
potentially read data that was not intended to be
disclosed. Note that this vulnerability would not allow
an attacker to execute code or to elevate their user
rights directly, but it could be used to obtain
information that could be used to try to further
compromise the affected system. (CVE-2020-0658)

arbitrary code in kernel mode. An attacker could then
install programs; view, change, or delete data; or
create new accounts with full user rights.
(CVE-2020-0691)
- An elevation of privilege vulnerability exists in Active
Directory Forest trusts due to a default setting that
lets an attacker in the trusting forest request
delegation of a TGT for an identity from the trusted
forest. (CVE-2020-0665)

if a .LNK file is processed. An attacker who
successfully exploited this vulnerability could gain the
same user rights as the local user. (CVE-2020-0729)
- An information disclosure vulnerability exists in the
way that Microsoft Graphics Components handle objects in
memory. An attacker who successfully exploited the
vulnerability could obtain information that could be
useful for further exploitation. (CVE-2020-0746)
- An information disclosure vulnerability exists when the
win32k component improperly provides kernel information.
An attacker who successfully exploited the vulnerability
could obtain information to further compromise the users
system. (CVE-2020-0717)
