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

Publish date: June 16, 2011
  Severity: CRITICAL
  CVE Identifier: CVE-2011-1271
  Advisory Date: JUN 16, 2011

  DESCRIPTION

A vulnerability in Microsoft .NET Framework could allow remote code execution on a computer if its user views a malicious Web page using a browser that can run XAML Browser Applications (XBAPs). Administrator user accounts are more at risk of this vulnerability than user accounts with lesser rights. The vulnerability could also allow remote code execution on a server system running IIS, if the server allows processing ASP.NET pages. If an attacker successfully uploads a malicious ASP.NET page to that server and then executes the page, as in a Web hosting scenario. Windows .NET applications can use this vulnerability to bypass Code Access Security (CAS) restrictions.
