KB2160841: .NET Framework 4.0 web app stops working

Modified: 2010/11/16 11:31 by jim - Categorized as: ASP.NET, IIS, Windows
After installing KB2160841 .NET Framework 4.0 web application on an SSL connection no longer functions. The patch fixes a security problem where an authenticated hacker could get information from among others encrypted viewstate. Long story short, after giving Authenticated User read rights the application works again.. In effect, this annuls the work of the patch, but it does get your web application working again. see (Dutch version) KB article
