How to use sqlmap when the injectable parameter is not a regular parameter?

Question

I have a target website, which parameter is not a regular parameter, which looks like:

POST /some_url

'info={"actual_parameter1": "abc", "actual_parameter2": "def"}'

info is not the actual_parameter, but the actual_parameter1 and actual_parameter2 are.

How can I use sqlmap in this case?

Answer 1

thanks to the comments of this question, there are 2 ways to do it:

1. use -p parameter, e.g. sqlmap -u test.com -p "a;b" --param-del=';'
2. use * symbol, in any where, e.g. in cookie, in header, in url, ... sqlmap is clever enough to know this special symbol.
