# Vuln description:
# DeluxeBB suffers many SQL Injections. They are caused, in part, by the extract() function
# used in header.php. I think this is a very bad practice. Attacker doesn't need
# register_globals turned On, and in this case that i'm showing you magic_quotes
# turned Off too.

# PoC:
# I reccomend to use first of all this SQL Injection to retrieve all table's name
# of the database thanks to informatin_schema. You can use it to retrieve the table prefix
# of the CMS.
