Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

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)

- 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 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 in the way that the tapisrv.dll handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
(CVE-2020-0737)

- An elevation of privilege vulnerability exists in the way that the Windows Kernel handles objects in memory.
An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
(CVE-2020-0668)

(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)

- An elevation of privilege vulnerability exists when the Windows Data Sharing Service improperly handles file operations. An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could exploit this vulnerability by running a specially crafted application on the victim system. The update addresses the vulnerability by correcting the way the Windows Data Sharing Service handles file operations. (CVE-2020-0659, CVE-2020-0747)

- 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-2020-0716)

- A remote code execution vulnerability exists in the way that Windows handles objects in memory. An attacker who successfully exploited the vulnerability could execute arbitrary code with elevated permissions on a target system. (CVE-2020-0662)

- An elevation of privilege vulnerability exists in the Windows Installer when MSI packages process symbolic links. An attacker who successfully exploited this vulnerability could bypass access restrictions to add or remove files. (CVE-2020-0683, CVE-2020-0686)

- An elevation of privilege vulnerability exists when the Windows Backup Service improperly handles file operations. (CVE-2020-0703)

- 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. (CVE-2020-0729)

- An elevation of privilege vulnerability exists when the Windows IME improperly handles memory. (CVE-2020-0707)

- An elevation of privilege vulnerability exists when the Windows Common Log File System (CLFS) driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2020-0657)

- An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run 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-2020-0719, CVE-2020-0720, CVE-2020-0721, CVE-2020-0722, CVE-2020-0723, CVE-2020-0724, CVE-2020-0725, CVE-2020-0726, CVE-2020-0731)

- An elevation of privilege vulnerability exists when the Connected User Experiences and Telemetry Service improperly handles file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges on the victim system.
(CVE-2020-0727)

- An elevation of privilege vulnerability exists when the Windows User Profile Service (ProfSvc) improperly handles symlinks. An attacker who successfully exploited this vulnerability could delete files and folders in an elevated context. (CVE-2020-0730)

- An elevation of privilege vulnerability exists in the way that the Windows Function Discovery Service handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. (CVE-2020-0679, CVE-2020-0680, CVE-2020-0682)

- An information disclosure vulnerability exists when the Windows Network Driver Interface Specification (NDIS) improperly handles memory. (CVE-2020-0705)
