PadBuster v0.3 and the .NET Padding Oracle Attack

Now that a weekend has passed since the .NET patch was released, and since there is already a working public example of how to reliably download a web.config using the padding oracle attack, we have decided to finally release v0.3 of PadBuster with the “Brute Force” option. This option is specifically designed to handle scenarios where the first block of ciphertext cannot be crafted using CBC-R due to a secret IV. This feature was NOT designed specifically for the .NET attack, as our intention for PadBuster is to be a universal tool for identifying and exploiting padding oracles in any web application. That being said, the brute force option CAN be used to reliably perform a web.config download attack within a reasonable number of requests
