MS11-044: Vulnerability in .NET Framework Could Allow Remote Code Execution (2538814)

high Nessus Plugin ID 55124


The version of the .NET Framework installed on the remote host allows arbitrary code execution.


The JIT compiler included with the version of the .NET Framework installed on the remote host incorrectly validates certain values within an object.

An attacker may be able to leverage this vulnerability to run arbitrary code as the logged in user or the user account of ASP.NET on the affected system under either of the following scenarios :

- Tricking a user on the affected host into viewing a specially crafted web page using a web browser that can run XAML Browser Applications (XBAPs).

- Uploading a malicious ASP.NET application to be hosted on the affected host.

- Bypassing Code Access Security (CAS) restrictions in a Windows .NET application.


Microsoft has released a set of patches for the .NET Framework on Windows XP, 2003, Vista, 2008, 7, and 2008 R2.
