high Nessus Plugin ID 109652

Language:

Synopsis

The Microsoft .NET Framework installation on the remote host is affected by multiple vulnerabilities.

Description

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

- A security feature bypass vulnerability exists in .Net Framework which could allow an attacker to bypass Device Guard. An attacker who successfully exploited this vulnerability could circumvent a User Mode Code Integrity (UMCI) policy on the machine. (CVE-2018-1039)

- A denial of service vulnerability exists when .NET and .NET Core improperly process XML documents. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to a .NET (or .NET core) application. The update addresses the vulnerability by correcting how .NET and .NET Core applications handle XML document processing.
(CVE-2018-0765)
