The Microsoft .NET Framework installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - An authentication bypass vulnerability exists in Windows     Communication Foundation (WCF) and Windows Identity     Foundation (WIF), allowing signing of SAML tokens with     arbitrary symmetric keys. This vulnerability allows an     attacker to impersonate another user, which can lead to     elevation of privileges. The vulnerability exists in     WCF, WIF 3.5 and above in .NET Framework, WIF 1.0     component in Windows, WIF Nuget package, and WIF     implementation in SharePoint. An unauthenticated     attacker can exploit this by signing a SAML token with     any arbitrary symmetric key. This security update     addresses the issue by ensuring all versions of WCF and     WIF validate the key used to sign SAML tokens correctly.
    (CVE-2019-1006)

  - A remote code execution vulnerability exists in .NET     software when the software fails to check the source     markup of a file. An attacker who successfully exploited     the vulnerability could run arbitrary code in the     context of the current user. If the current user is     logged on with administrative user rights, an attacker     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-2019-1113)

  - A denial of service vulnerability exists when Microsoft     Common Object Runtime Library improperly handles web     requests. An attacker who successfully exploited this     vulnerability could cause a denial of service against a     .NET web application. A remote unauthenticated attacker     could exploit this vulnerability by issuing specially     crafted requests to the .NET application. The update     addresses the vulnerability by correcting how the .NET     web application handles web requests. (CVE-2019-1083)

The remote Windows host is missing security update 4507461 or cumulative update 4507452. It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in Remote     Desktop Services formerly known as Terminal Services     when an authenticated attacker abuses clipboard     redirection. An attacker who successfully exploited this     vulnerability could execute arbitrary code on the victim     system. An attacker could then install programs; view,     change, or delete data; or create new accounts with full     user rights.  (CVE-2019-0887)

  - 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-2019-1063)

  - A remote code execution vulnerability exists in .NET     software when the software fails to check the source     markup of a file. An attacker who successfully exploited     the vulnerability could run arbitrary code in the     context of the current user. If the current user is     logged on with administrative user rights, an attacker     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-2019-1113)

  - 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-2019-1102)

  - A remote code execution vulnerability exists in the way     that the scripting engine handles objects in memory in     Internet Explorer. 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-2019-1004, CVE-2019-1059)

  - A denial of service vulnerability exists when Microsoft     Common Object Runtime Library improperly handles web     requests. An attacker who successfully exploited this     vulnerability could cause a denial of service against a     .NET web application. A remote unauthenticated attacker     could exploit this vulnerability by issuing specially     crafted requests to the .NET application. The update     addresses the vulnerability by correcting how the .NET     web application handles web requests. (CVE-2019-1083)

  - A remote code execution vulnerability exists in the way     that Microsoft browsers access objects in memory. The     vulnerability could corrupt memory in a way that could     allow an attacker to 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-2019-1104)

  - An information disclosure vulnerability exists when     DirectWrite improperly discloses the contents of its     memory. An attacker who successfully exploited the     vulnerability could obtain information to further     compromise the users system. 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 an untrusted webpage.
    The security update addresses the vulnerability by     correcting how DirectWrite handles objects in memory.
    (CVE-2019-1093, CVE-2019-1097)

  - An information disclosure vulnerability exists when the     Windows GDI component improperly discloses the contents     of its memory. An attacker who successfully exploited     the vulnerability could obtain information to further     compromise the users system. 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 an untrusted webpage.
    The security update addresses the vulnerability by     correcting how the Windows GDI component handles objects     in memory. (CVE-2019-1094, CVE-2019-1095, CVE-2019-1098,     CVE-2019-1099, CVE-2019-1100, CVE-2019-1101,     CVE-2019-1116)

  - 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 users     system. An authenticated attacker could exploit this     vulnerability by running a specially crafted     application. The update addresses the vulnerability by     correcting how the Windows kernel handles objects in     memory. (CVE-2019-1071)

  - An information disclosure vulnerability exists when the     Windows RDP client improperly discloses the contents of     its memory. An attacker who successfully exploited this     vulnerability could obtain information to further     compromise the users system.  (CVE-2019-1108)

  - An authentication bypass vulnerability exists in Windows     Communication Foundation (WCF) and Windows Identity     Foundation (WIF), allowing signing of SAML tokens with     arbitrary symmetric keys.

The vulnerability exists in     WCF, WIF 3.5 and above in .NET Framework, WIF 1.0     component in Windows, WIF Nuget package, and WIF     implementation in SharePoint. An unauthenticated     attacker can exploit this by signing a SAML token with     any arbitrary symmetric key. This security update     addresses the issue by ensuring all versions of WCF and     WIF validate the key used to sign SAML tokens correctly.
    (CVE-2019-1006)

  - 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 users     system.  (CVE-2019-1073)

  - 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-2019-1132)

  - An elevation of privilege exists in Windows Audio     Service. An attacker who successfully exploited the     vulnerability could run arbitrary code with elevated     privileges.  (CVE-2019-1088)
