Microsoft: >> Windows Server 2016 >> 1803 Security Vulnerabilities
An information disclosure vulnerability exists when the Windows RDP server improperly discloses the contents of its memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the system.
To exploit this vulnerability, an attacker would have to connect remotely to an affected system and run a specially crafted application.
The security update addresses the vulnerability by correcting how the Windows RDP server initializes memory.

A remote code execution vulnerability exists in Remote Desktop Services – formerly known as Terminal Services – when an unauthenticated attacker connects to the target system using RDP and sends specially crafted requests. This vulnerability is pre-authentication and requires no user interaction. An attacker who successfully exploited this vulnerability could execute arbitrary code on the target system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit this vulnerability, an attacker would need to send a specially crafted request to the target systems Remote Desktop Service via RDP.
The update addresses the vulnerability by correcting how Remote Desktop Services handles connection requests.

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 user’s system.
To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system.
The update addresses the vulnerability by correcting how the Windows kernel handles objects in memory.

An elevation of privilege vulnerability exists in the way that the wcmsvc.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 wcmsvc.dll properly handles objects in memory.

A denial of service vulnerability exists when the XmlLite runtime (XmlLite.dll) improperly parses XML input. An attacker who successfully exploited this vulnerability could cause a denial of service against an XML application.
A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to an XML application.
The update addresses the vulnerability by correcting how the XmlLite runtime parses XML input.

A remote code execution vulnerability exists in Microsoft Windows that could allow remote code execution if a .LNK file is processed.
An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
The attacker could present to the user a removable drive, or remote share, that contains a malicious .LNK file and an associated malicious binary. When the user opens this drive(or remote share) in Windows Explorer, or any other application that parses the .LNK file, the malicious binary will execute code of the attacker’s choice, on the target system.
The security update addresses the vulnerability by correcting the processing of shortcut LNK references.

An elevation of privilege exists in SyncController.dll. An attacker who successfully exploited the vulnerability could run arbitrary code with elevated privileges.
To exploit the vulnerability, an attacker could run a specially crafted application that could exploit the vulnerability. This vulnerability by itself does not allow arbitrary code to be run. However, this vulnerability could be used in conjunction with one or more vulnerabilities (e.g. a remote code execution vulnerability and another elevation of privilege) that could take advantage of the elevated privileges when running.
The update addresses the vulnerability by correcting how the SyncController.dll handles processes these requests.

An information disclosure vulnerability exists in SymCrypt during the OAEP decryption stage. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.
To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system.
The update addresses the vulnerability through a software change to the OAEP decoding operations.

An information disclosure vulnerability exists in Azure Active Directory (AAD) Microsoft Account (MSA) during the login request session. An attacker who successfully exploited the vulnerability could take over a user's account.
To exploit the vulnerability, an attacker would have to trick a user into browsing to a specially crafted website, allowing the attacker to steal the user's token.
The security update addresses the vulnerability by correcting how MSA handles cookies.
