I am currently having trouble with level7 injection. I know what and where the exploit is but my injection is not working.
I am able to do a similar injection on my own box, but when I try it on the level 7 it doesn't work.
When I insert my injection without comments to cancel out the rest of the PHP, I just get a blank page. Can I just PM someone who has completed it because I do not want to give out a big spoiler.
Nevermind, I solved it. I was missing one character. But this challenge was AWESOME!!!!
