Synopsis
The remote Windows host is affected by multiple vulnerabilities.Description
The remote Windows host is missing security update 4534309 or cumulative update 4534297. It is, therefore, affected by multiple vulnerabilities :- An elevation of privilege vulnerability exists in the way that the Windows Search Indexer handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. (CVE-2020-0613, CVE-2020-0614, CVE-2020-0623, CVE-2020-0625, CVE-2020-0626, CVE-2020-0627, CVE-2020-0628, CVE-2020-0629, CVE-2020-0630, CVE-2020-0631, CVE-2020-0632)
- A remote code execution vulnerability exists in Windows Remote Desktop Gateway (RD Gateway) 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. (CVE-2020-0609, CVE-2020-0610)
- 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-2020-0615, CVE-2020-0639)
- 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-2020-0642)
- An information disclosure vulnerability exists when Remote Desktop Web Access improperly handles credential information. An attacker who successfully exploited this vulnerability could obtain legitimate users' credentials. (CVE-2020-0637)
- 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-2020-0643)
- 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-2020-0640)
- An elevation of privilege vulnerability exists in Microsoft Windows when Windows fails to properly handle certain symbolic links. An attacker who successfully exploited this vulnerability could potentially set certain items to run at a higher level and thereby elevate permissions. (CVE-2020-0635)
- 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-2020-0608)
- An elevation of privilege vulnerability exists when Microsoft Cryptographic Services improperly handles files. An attacker could exploit the vulnerability to overwrite or modify a protected file leading to a privilege escalation. (CVE-2020-0620)
- 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-2020-0634)
- An elevation of privilege vulnerability exists in Windows Media Service that allows file creation in arbitrary locations. (CVE-2020-0641)
- 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-2020-0607)
- 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-2020-0611)
- An elevation of privilege vulnerability exists when Microsoft Windows implements predictable memory section names. An attacker who successfully exploited this vulnerability could run arbitrary code as system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2020-0644)
