ASP ViewState does not show up

Nikolaus | Last updated: Jun 24, 2020 03:48AM UTC

I have an issue with the ViewState Tab not showing up in the Request/Response view I can see the hidden form elements and on a POST request I can see the Parameters being sent, but the Tab is not showing up. Here is a screenshot of the proxy history, where you can see the ViewState in the Params, but no Tab for it: https://imgur.com/a/erYqMbR

That tab was removed. I have added your ticket to our internal one to re-implement the tab. In the meantime, you could attempt to edit the code for .NET Beautifier: https://portswigger.net/bappstore/e2a137ad44984ccb908375fa5b2c618d.

I experience the same issue, I don't understand why to remove this tab in the first place. I'd appreciate it if it will be re-implemented.

Thanks for the feedback! We will update this thread if/when the feature is reimplemented. Have you considered using .NET Beautifier as a workaround?

Hi We have just released an extension in the BApp Store for displaying and editing ViewState data. You can find it on the BApp Store here: https://portswigger.net/bappstore/ba17d9fb487448b48368c22cb70048dc
