Well, I think I achieved this by leaving the fields blank (fields
1-7), then putting the following crap values in by typing the
following into the browser:
http://localhost:8080/WebGoat/attack?field1=crap&field2=crap&field3=crap&field4=crap&field5=crap&field6=crap&field7=crap

This gave me...

Parameters from HTTP Request
field1 -> crap
field2 -> crap
field3 -> crap
field4 -> crap
field5 -> crap
field6 -> crap
field7 -> crap

*
Server side validation violation: You succeeded for Field1.
Server side validation violation: You succeeded for Field2.
Server side validation violation: You succeeded for Field4.
Server side validation violation: You succeeded for Field5.
Server side validation violation: You succeeded for Field6.
Server side validation violation: You succeeded for Field7.


I didn't get the clientside validation error (javascript found form
errors: bad field1 etc) and the fields were populated with the "crap"
strings.

The hints for this lesson are as follows:

- The validation is happening in your browser.
- Try modifying the values with a proxy after they leave your browser
- Another way is to delete the JavaScript before you view the page


Cheers,

Vanessa
