MS12-025: Vulnerability in .NET Framework Could Allow Remote Code Execution (2671605)

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The .NET Framework install on the remote Windows host could allow
arbitrary code execution.

Description :

The version of the .NET Framework installed on the remote host
reportedly is affected by a code execution vulnerability because of
the way .NET Framework validates parameters when passing data to a
function.

An attacker may be able to leverage these vulnerabilities to execute
arbitrary code on the affected system if a user can be tricked into
viewing a specially crafted web page using a web browser that can run
XAML Browser Applications (XBAPs). The vulnerability could also be
exploited by uploading a specially crafted ASP.NET page to a server
system running IIS and then executing that page.
