//找回密码第2步
elseif ($act=='get_pass')
{
$captcha=get_cache('captcha');
$postcaptcha = trim($_POST['postcaptcha']);
if($captcha['verify_getpwd']=='1' && empty($postcaptcha))
{
showmsg("请填写验证码",1);
}
if ($captcha['verify_getpwd']=='1' && strcasecmp($_SESSION['imageCaptcha_content'],$postcaptcha)!=0)
{
showmsg("验证码错误",1);
}
$postusername=trim($_POST['username'])?trim($_POST['username']):showmsg('请输入用户名!',1);
if (empty($_POST['email']) || !preg_match("/^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/",$_POST['email']))
{
showmsg('电子邮箱格式错误!',1);
}
require_once(QISHI_ROOT_PATH.'include/fun_user.php');
$userinfo=get_user_inusername($postusername);
if (empty($userinfo) || $userinfo['email']<>$_POST['email'])
{
showmsg('用户名或注册邮箱填写错误',1);
}
else
{
$mailconfig=get_cache('mailconfig');
$arr['username']=$userinfo['username'];
$arr['password']=rand(100000,999999);
if (smtp_mail($userinfo['email'],"找回密码","您的新密码为:".$arr['password']))
{
$md5password=md5(md5($arr['password']).$userinfo['pwd_hash'].$QS_pwdhash);
if (!$db->query( "UPDATE ".table('members')." SET password = '$md5password' WHERE uid='{$userinfo['uid']}'"))
{
showmsg('密码修改失败',1);
}
$smarty->assign('step',"2");
$smarty->assign('email',$userinfo['email']);
$smarty->assign('title','找回密码 - '.$_CFG['site_name']);
$smarty->display('user/getpass.htm');
}
else
{
showmsg('邮件发送失败,请联系网站管理员',0);
}
}
}
最后就是剩下的,来爆破重置之后的密码了,因为此系统安装后默认是不开启登陆验证码的,就算开启验证码我们也可以进行爆破。
