A security feature bypass vulnerability exists in Microsoft Windows when a man-in-the-middle attacker is able to successfully bypass the NTLMv2 protection if a client is also sending LMv2 responses, aka 'Windows NTLM Security Feature Bypass Vulnerability'.

The remote Windows host is missing security update 4520009 or cumulative update 4520002. It is, therefore, affected by multiple vulnerabilities :

  - 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-2019-1358, CVE-2019-1359)

  - 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-2019-1371)

  - 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-2019-1333)

  - A security feature bypass vulnerability exists in     Microsoft Windows when a man-in-the-middle attacker is     able to successfully bypass the NTLMv2 protection if a     client is also sending LMv2 responses. An attacker who     successfully exploited this vulnerability could gain the     ability to downgrade NTLM security features.
    (CVE-2019-1338)

  - A tampering vulnerability exists in Microsoft Windows     when a man-in-the-middle attacker is able to     successfully bypass the NTLM MIC (Message Integrity     Check) protection. An attacker who successfully     exploited this vulnerability could gain the ability to     downgrade NTLM security features.  (CVE-2019-1166)

  - A denial of service vulnerability exists when Windows     improperly handles objects in memory. An attacker who     successfully exploited the vulnerability could cause a     target system to stop responding.  (CVE-2019-1346)

  - A spoofing vulnerability exists when Transport Layer     Security (TLS) accesses non- Extended Master Secret     (EMS) sessions. An attacker who successfully exploited     this vulnerability may gain access to unauthorized     information.  (CVE-2019-1318)

  - A remote code execution vulnerability exists in the way     that the VBScript engine handles 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-2019-1238)

  - 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-2019-1326)

  - An elevation of privilege vulnerability exists in     Windows when the Windows kernel-mode driver 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-2019-1362, CVE-2019-1364)

  - An elevation of privilege vulnerability exists when     Windows Error Reporting manager improperly handles a     process crash. An attacker who successfully exploited     this vulnerability could delete a targeted file leading     to an elevated status.  (CVE-2019-1342)

  - An information disclosure vulnerability exists in the     way that the Windows Code Integrity Module handles     objects in memory. An attacker who successfully     exploited this vulnerability could obtain information to     further compromise the users system.  (CVE-2019-1344)

  - An elevation of privilege vulnerability exists when     Windows Error Reporting manager improperly handles hard     links. An attacker who successfully exploited this     vulnerability could overwrite a targeted file leading to     an elevated status.  (CVE-2019-1315, CVE-2019-1339)

  - An elevation of privilege vulnerability exists when     Microsoft IIS Server fails to check the length of a     buffer prior to copying memory to it. An attacker who     successfully exploited this vulnerability can allow an     unprivileged function ran by the user to execute code in     the context of NT AUTHORITY\system escaping the Sandbox.
    The security update addresses the vulnerability by     correcting how Microsoft IIS Server sanitizes web     requests. (CVE-2019-1365)

  - 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-2019-1319)

  - A spoofing vulnerability exists when Microsoft Browsers     does not properly parse HTTP content. An attacker who     successfully exploited this vulnerability could     impersonate a user request by crafting HTTP queries. The     specially crafted website could either spoof content or     serve as a pivot to chain an attack with other     vulnerabilities in web services.  (CVE-2019-0608)

  - An elevation of privilege vulnerability exists when     umpo.dll of the Power Service, improperly handles a     Registry Restore Key function. An attacker who     successfully exploited this vulnerability could delete a     targeted registry key leading to an elevated status.
    (CVE-2019-1341)

  - 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-2019-1363)
