I've been through all of the 'Basic Web Hacking' challenges (apart from 24.) without too much difficulty, but I'm absolutely stumped on 29.
I've tried what feels like every possible combination of XP**H In*******s I can think of, and no results have been yielded.
I've got the d***g parameter in the URL and the query that it shows me after my In*******s looks like it should be working.
Could anyone PM me some pointers on how to pwn this challenge please?
