ecisp_member_info的构成：

$this->fun->setcookie('ecisp_member_info', $this->fun->eccode("500|$rsMember[alias]|$rsMember[integral]|$rsMember[mcid]|$rsMember[email]|$rsMember[lastip]|$ipadd|" . md5($_SERVER['HTTP_USER_AGENT']) . '|' . md5(admin_ClassURL), 'ENCODE', db_pscode));

从代码中可以看出验证用户真正用到的是userid   也就是说cookie中ecisp_member_info真正起到作用的是userid部分   userid只占用了cookie ecisp_member_info字符串中很少的字符   而这一部分字符才是起到作用的，其他的无关紧要，这样的验证是不是很弱呢？   那我们是不是可以去爆破它呢？   我们拿官方演示站来做一下演示：
