Synopsis
The remote Windows host is affected by multiple vulnerabilities.
Description
The remote Windows host is missing security update 4556799. It is, therefore, affected by multiple vulnerabilities :
- A denial of service vulnerability exists when .NET Core or .NET Framework improperly handles web requests. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET Core or .NET Framework web application. The vulnerability can be exploited remotely, without authentication. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to the .NET Core or .NET Framework application. The update addresses the vulnerability by correcting how the .NET Core or .NET Framework web application handles web requests. (CVE-2020-1108)
- An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. 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 an untrusted webpage. The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. (CVE-2020-0963, CVE-2020-1179)
- An elevation of privilege vulnerability exists when Windows improperly handles calls to Clipboard Service. An attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the local system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2020-1111, CVE-2020-1121, CVE-2020-1165, CVE-2020-1166)
- A remote code execution vulnerability exists when Microsoft Edge PDF Reader improperly handles objects in memory. The vulnerability could corrupt memory in such a way that enables an attacker to 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 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-2020-1096)
- A denial of service vulnerability exists when Hyper-V on a Windows Server fails to properly handle specially crafted network packets. (CVE-2020-0909)
- A cross-site-scripting (XSS) vulnerability exists when Active Directory Federation Services (ADFS) does not properly sanitize user inputs. An un-authenticated attacker could exploit the vulnerability by sending a specially crafted request to an affected ADFS server. The attacker who successfully exploited the vulnerability could then perform cross-site scripting attacks on affected systems and run scripts in the security context of the current user. This security update addresses the vulnerability by ensuring that ADFS properly sanitizes user inputs. (CVE-2020-1055)
- An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2020-1072)

"The remote Windows host is missing security update 4556799.
It is, therefore, affected by multiple vulnerabilities :
- A denial of service vulnerability exists when .NET Core
or .NET Framework improperly handles web requests. An
attacker who successfully exploited this vulnerability
could cause a denial of service against a .NET Core or
.NET Framework web application. The vulnerability can be
exploited remotely, without authentication. A remote
unauthenticated attacker could exploit this
vulnerability by issuing specially crafted requests to
the .NET Core or .NET Framework application. The update
addresses the vulnerability by correcting how the .NET
Core or .NET Framework web application handles web
requests. (CVE-2020-1108)
- An information disclosure vulnerability exists when the
Windows GDI component improperly discloses the contents
of its memory. An attacker who successfully exploited
the vulnerability could obtain information to further
compromise the users system. 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 an untrusted webpage.
The security update addresses the vulnerability by
correcting how the Windows GDI component handles objects
in memory. (CVE-2020-0963, CVE-2020-1179)
- An elevation of privilege vulnerability exists when
Windows improperly handles calls to Clipboard Service.
An attacker who successfully exploited this
vulnerability could run arbitrary code in the security
context of the local system. An attacker could then
install programs; view, change, or delete data; or
create new accounts with full user rights.
(CVE-2020-1111, CVE-2020-1121, CVE-2020-1165,
CVE-2020-1166)
- A remote code execution vulnerability exists when
Microsoft Edge PDF Reader improperly handles objects in
memory. The vulnerability could corrupt memory in such a
way that enables an attacker to 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 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-2020-1096)
- A denial of service vulnerability exists when Hyper-V on
a Windows Server fails to properly handle specially
crafted network packets. (CVE-2020-0909)

Active Directory Federation Services (ADFS) does not
properly sanitize user inputs. An un-authenticated
attacker could exploit the vulnerability by sending a
specially crafted request to an affected ADFS server.
The attacker who successfully exploited the
vulnerability could then perform cross-site scripting
attacks on affected systems and run scripts in the
security context of the current user. This security
update addresses the vulnerability by ensuring that ADFS
properly sanitizes user inputs. (CVE-2020-1055)
- An information disclosure vulnerability exists when the

with full user rights. (CVE-2020-1142)
- An elevation of privilege vulnerability exists when the
Windows Print Spooler service improperly allows
arbitrary writing to the file system. An attacker who
successfully exploited this vulnerability could run
arbitrary code with elevated system privileges. An
attacker could then install programs; view, change, or
delete data; or create new accounts with full user
rights. (CVE-2020-1048, CVE-2020-1070)
- An elevation of privilege vulnerability exists in

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-2020-1021, CVE-2020-1082,
CVE-2020-1088)

- An information disclosure vulnerability exists in the
way that the Windows Graphics Device Interface (GDI)
handles objects in memory, allowing an attacker to
retrieve information from a targeted system. By itself,
the information disclosure does not allow arbitrary code
execution; however, it could allow arbitrary code to be
run if the attacker uses it in combination with another
vulnerability. (CVE-2020-1141, CVE-2020-1145)
- An elevation of privilege vulnerability exists when the
Storage Service improperly handles file operations. An
attacker who successfully exploited this vulnerability
could gain elevated privileges on the victim system.

application. The update addresses the vulnerability by
correcting how Windows Subsystem for Linux handles
objects in memory. (CVE-2020-1075)
- A remote code execution vulnerability exists when
Internet Explorer improperly accesses objects in memory.
The vulnerability could corrupt memory in such a 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. (CVE-2020-1062,
CVE-2020-1092)

policies, which could allow an attacker to access
information from one domain and inject it into another
domain. (CVE-2020-1056)
