Description
The remote Windows Server 2012 host is missing either the KB4025331 or KB4025343 security updates. It is, therefore, affected by the following vulnerabilities :

- An information disclosure vulnerability exists in the Windows Performance Monitor Console due to improper parsing of XML input that contains a reference to an external entity. An unauthenticated, remote attacker can exploit this, by convincing a user to create a Data Collector Set and import a specially crafted XML file, to disclose arbitrary files via an XML external entity (XXE) declaration. (CVE-2017-0170)

Solution
Apply one of the following security updates :

- KB4025331
- KB4025343

http://www.nessus.org/u?23066c63
http://www.nessus.org/u?6eb83bb8

Output
  •   The registry key "SYSTEM\CurrentControlSet\Services\NTDS\Parameters\LdapEnforceChannelBinding"
  is missing or is not equal to "1" or "2"


Remediation : 

Even after applying the update you will see that Nessus still detects it as an vulnerability. In order to fully mitigate it you need to create the following entries 


To help make LDAP authentication over SSL\TLS more secure, administrators can configure the following registry settings:

  • Path for Active Directory Domain Services (AD DS) domain controllers: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NTDS\Parameters
  • Path for Active Directory Lightweight Directory Services (AD LDS) servers: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<LDS instance name>\Parameters
  • DWORD Name: LdapEnforceChannelBinding (Microsoft article has made a mistake and lists the DWORD Name as a Key which is incorrect )
  • DWORD value: 0 indicates disabled. No channel binding validation is performed. This is the behavior of all servers that have not been updated.
  • DWORD value: 1 indicates enabled, when supported. All clients that are running on a version of Windows that has been updated to support channel binding tokens (CBT) must provide channel binding information to the server. Clients that are running a version of Windows that has not been updated to support CBT do not have to do so. This is an intermediate option that allows for application compatibility.
  • DWORD value: 2 indicates enabled, always. All clients must provide channel binding information. The server rejects authentication requests from clients that do not do so.

Nessus :Microsoft XML Parser (MSXML) and XML Core Services Unsupported

Microsoft XML Parser (MSXML) and XML Core Services Unsupported


Description
The remote host contains one or more unsupported versions of the Microsoft XML Parser (MSXML) or XML Core Services.

Lack of support implies that no new security patches for the product will be released by the vendor. As a result, it is likely to contain security vulnerabilities.

Note that support for MSXML 3.0 and 6.0 is based on the support policy of the operating system on which it is installed. Support for MSXML 5.0 is based on the Microsoft Office lifecycle policy.


Solution
Upgrade the software packages responsible for the unsupported DLL versions or upgrade to a supported version of Windows (Vista / 2008 or later). Alternatively, uninstall the outdated MSXML or XML Core Services.

Resolution:



 In most cases these are unnecessary files and there are no good way to remove these . Browse to the C:\Windows\SysWOW64\msxml4.dll location .Copy the Msml14.dll to another location ( not necessary but as an insurance against eventualities ) and then delete the file or rename it.  Your next Nessus scan would show the issue as resolved . MSXML 4.0 is not needed for general OS usage and is no longer supported by Microsoft.

- Multiple remote code execution vulnerabilities exist in     Internet
 Explorer due to improper handling of objects in     memory. An 
unauthenticated, remote attacker can exploit     these, by convincing a 
user to visit a specially crafted     website, to execute arbitrary code
 in the context of the     current user. (CVE-2017-8519, CVE-2017-8547)



- A remote code execution vulnerability exists in     Microsoft 
browsers in the JavaScript engines due to     improper handling of 
objects in memory. An     unauthenticated, remote attacker can exploit 
this, by     convincing a user to visit a specially crafted website,    
 to execute arbitrary code in the context of the current     user. 
(CVE-2017-8524)



- A remote code execution vulnerability exists in the     Windows font
 library due to improper handling of     embedded fonts. An 
unauthenticated, remote attacker can     exploit this, by convincing a 
user to visit a specially     crafted website or open a specially 
crafted Microsoft     document, to execute arbitrary code in the context
 of     the current user. (CVE-2017-8527)



- An information disclosure vulnerability exists in     Microsoft 
browsers in the scripting engines due to     improper handling of 
objects in memory. An     unauthenticated, remote attacker can exploit 
this, by     convincing a user to visit a specially crafted website,    
 to disclose files on a user's computer. (CVE-2017-8529)*



- A remote code execution vulnerability exists in the     Windows 
Search functionality due to improper handling of     objects in memory. 
An unauthenticated, remote attacker     can exploit this, via a 
specially crafted SMB message,     to execute arbitrary code. 
(CVE-2017-8543)



- An information disclosure vulnerability exists in the     Windows 
Search functionality due to improper handling of     objects in memory. 
An unauthenticated, remote attacker     can exploit this, via a 
specially crafted SMB message,     to disclose sensitive information. 
(CVE-2017-8544)



- Multiple information disclosure vulnerabilities exist in     the 
Windows kernel due to improper handling of objects     in memory. An
