  Vulnerability Details:

  .NET Framework 2.0 Cross-Site Scripting Vulnerability - CVE-2006-3436:

  A cross-site scripting vulnerability may exist in a server running a
  vulnerable version of the .Net Framework 2.0 that could inject a client side
  script in the user's browser. The vulnerability is within ASP.NET controls
  that set the AutoPostBack property to "true". In a Web-based attack scenario
  a compromised Web site could accept or host user-provided content or 
  advertisements which could contain specially crafted content that could 
  exploit this vulnerability.

  The script could take any action on the user's behalf that the Web site is
  authorized to take. This could include monitoring the Web session and 
  forwarding information to a third party, running other code on the user's
  system, and reading or writing cookies.
