Description

There is an information disclosure vulnerability in ASP.NET, part of the .NET framework. Information can be leaked due to improper error handling during encryption padding.

A remote attacker could exploit this to decrypt and modify an ASP.NET application's server-encrypted data. In .NET Framework 3.5 SP1 and above, an attacker could exploit this to download any file within the ASP.NET application, including web.config.
