/*
notes:
works regardless of magic_quotes_gpc settings...
there is some magic quotes disable code in variable_class.php near line 120-145
also you can always disclose table prefix...
we have different number of columns in older version, we will shortly bruteforce query

oh, we have two xss even:
http://[target]/[path_to_papoo]/interna/hilfe.php?titel=[XSS]
http://[target]/[path_to_papoo]/interna/hilfe.php?ausgabe=[XSS]
