Intro
Schoolhos CMS is alternative to developing School Website. It's Free and Open Source under GPL License. Easy to install, user friendly and elegant design.
Schoolhos is vulnerable to unauthenticated remote code execution vulnerability , Unauthenticated sql injection flaws
I - Remote code execution
File : process.php
Line : 42
elseif ($pilih=='guru' AND $untukdi=='upload'){
$lokasi_file = $_FILES['fupload']['tmp_name'];
$nama_file = $_FILES['fupload']['name'];
UploadMateri($nama_file);
File : file_uplaod.php
Line : 9
function UploadMateri($fupload_name){
//direktori file dari halaman e-elarning
$vdir_upload = "../file/materi/";
$vfile_upload = $vdir_upload . $fupload_name;
move_uploaded_file($_FILES["fupload"]["tmp_name"], $vfile_upload);

Script is really full of injection flaws , mentioning all of it is such waste of time
