You're right... but not at all. This script is created with the intention to take the control of any platform, I invite you to try it with wordpress platform and tell me your opinion.
Of course if u upload a shell, u can get access to entire site, but u need to put every query manually... no with the script.
What I mean: this script is oriented to take control of any platform, obviously it can't compares with a shell.
