A simple but useful Burp extension to increment a parameter in each request, intended for use with Active Scan.
An example use case would be if you are active scanning a "create user" form, which would normally produce an error if you created two users with the same username. You can use the text IncrementMePlease for the username parameter parameter and it will replace it with Incremented[RandomInt][Counter], so that you can successfully active scan this form.
The extension also supports IntMePlease and FloatMePlease that will replace the text with an integer or float starting from 1. If you need the counter to start at another number, append this to the end of the string such as IntMePlease2 or FloatMePlease10.0. To reset or change the numberin again, you'll need to unload and then load the extension.
Lastly, the extension support a random GUID with the string GUIDMePlease
It will match:
{"name":"IncrementMePlease"}
And replace it with:
{"name":"Incremented291706"}
...
{"name":"Incremented291707"}
...
{"name":"Incremented291708"}
It will match:
{"name":"IntMePlease"}
And replace it with:
{"name":"1"}
...
{"name":"2"}
...
{"name":"3"}
or
It will match:
{"name":"IntMePlease5"}
And replace it with:
{"name":"6"}
...
{"name":"7"}
...
{"name":"8"}
It will match:
{"name":"GUIDMePlease"}
And replace it with:
{"name":"c2d733ef-dca0-468a-ad8e-3eb687e9a8a3"}
...
{"name":"606a6c73-f5e0-4049-9a18-7a1929029e27"}
...
{"name":"b9839038-a2a4-4ff1-b22c-e7213b292dff"}
