high Nessus Plugin ID 141434

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4580346.
It is, therefore, affected by multiple vulnerabilities :

- A spoofing vulnerability exists when Windows incorrectly validates file signatures. An attacker who successfully exploited this vulnerability could bypass security features and load improperly signed files. In an attack scenario, an attacker could bypass security features intended to prevent improperly signed files from being loaded. The update addresses the vulnerability by correcting how Windows validates file signatures.
(CVE-2020-16922)

- A remote code execution vulnerability exists when the Windows Jet Database Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system. An attacker could exploit this vulnerability by enticing a victim to open a specially crafted file. The update addresses the vulnerability by correcting the way the Windows Jet Database Engine handles objects in memory. (CVE-2020-16924)

- A remote code execution vulnerability exists when Windows Network Address Translation (NAT) fails to properly handle UDP traffic. (CVE-2020-16894)

- An elevation of privilege vulnerability exists when the Windows Storage VSP Driver improperly handles file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges.
(CVE-2020-16885)

- A remote code execution vulnerability exists in the way that Microsoft Graphics Components handle objects in memory. An attacker who successfully exploited the vulnerability could execute arbitrary code on a target system. (CVE-2020-1167, CVE-2020-16923)

- A remote code execution vulnerability exists when Windows Hyper-V on a host server fails to properly validate input from an authenticated user on a guest operating system. (CVE-2020-16891)

- An elevation of privilege vulnerability exists in the way that the Windows kernel image handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. (CVE-2020-16892)

- An information disclosure vulnerability exists in the way that the Windows Graphics Device Interface Plus (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-2020-16914)

- An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker 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. The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation. (CVE-2020-16902)

- An elevation of privilege vulnerability exists when the Windows Storage Services improperly handle file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges.
(CVE-2020-0764)

- An information disclosure vulnerability exists in Remote Desktop Protocol (RDP) when an attacker connects to the target system using RDP and sends specially crafted requests. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2020-16896)

- A remote code execution vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in the memory. An attacker who successfully exploited this vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2020-16911)

- An information disclosure vulnerability exists when NetBIOS over TCP (NBT) Extensions (NetBT) improperly handle objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2020-16897)

- An elevation of privilege vulnerability exists when the Windows Application Compatibility Client Library improperly handles registry operations. An attacker who successfully exploited this vulnerability could gain elevated privileges. (CVE-2020-16876, CVE-2020-16920)

- 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-2020-16915)

- An elevation of privilege vulnerability exists when the Windows User Profile Service (ProfSvc) improperly handles junction points. An attacker who successfully exploited this vulnerability could delete files and folders in an elevated context. (CVE-2020-16940)

- A security feature bypass vulnerability exists when Microsoft Windows fails to handle file creation permissions, which could allow an attacker to create files in a protected Unified Extensible Firmware Interface (UEFI) location. (CVE-2020-16910)

- An elevation of privilege vulnerability exists when Group Policy improperly checks access. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2020-16939)

- 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-2020-16905, CVE-2020-16909)

- A denial of service vulnerability exists when Microsoft Hyper-V on a host server fails to properly validate specific malicious data from a user on a guest operating system. (CVE-2020-1243)

- A denial of service vulnerability exists in Remote Desktop Protocol (RDP) when an attacker connects to the target system using RDP and sends specially crafted requests. An attacker who successfully exploited this vulnerability could cause the RDP service on the target system to stop responding. (CVE-2020-16927)

- An elevation of privilege vulnerability exists in the way that the Windows Network Connections Service handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. (CVE-2020-16887)

- An elevation of privilege vulnerability exists when the Windows Backup Service improperly handles file operations. (CVE-2020-16912, CVE-2020-16936, CVE-2020-16972, CVE-2020-16973, CVE-2020-16974, CVE-2020-16975, CVE-2020-16976)

- An information disclosure vulnerability exists when the .NET Framework improperly handles objects in memory. An attacker who successfully exploited the vulnerability could disclose contents of an affected system's memory.
(CVE-2020-16937)

- An information disclosure vulnerability exists when the Windows KernelStream improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2020-16889)

- An elevation of privilege vulnerability exists when the Windows iSCSI Target Service improperly handles file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges.
(CVE-2020-16980)

- An elevation of privilege vulnerability exists when Windows improperly handles COM object creation. An attacker who successfully exploited the vulnerability could run arbitrary code with elevated privileges.
(CVE-2020-16916, CVE-2020-16935)

- An elevation of privilege vulnerability exists when the Windows Event System improperly handles objects in memory. (CVE-2020-16900)

- An information disclosure vulnerability exists when the Windows Enterprise App Management Service improperly handles certain file operations. An attacker who successfully exploited this vulnerability could read arbitrary files. An attacker with unprivileged access to a vulnerable system could exploit this vulnerability.
The security update addresses the vulnerability by ensuring the Windows Enterprise App Management Service properly handles file operations. (CVE-2020-16919)
