File Upload from URL Script

Description

This script is written in PHP and allows downloading a file from a specified URL and saving it on the server. To successfully execute this script, the user must enter a valid password.

Usage

1. Upload the script to your server.
2. Open the script URL in a browser.
3. Enter the file URL you wish to download in the input field.
4. Enter the correct password (12348).
5. Click the Up button.

If the entered information is correct, the file will be stored in the root directory of the server.

Requirements

• A server with PHP enabled.
• Write permissions in the directory where the script is executed.

Security Notes

• This script is vulnerable due to the use of a fixed password. It is recommended to use a stronger authentication system.
• Input validation is not performed, making it susceptible to attacks such as Injection.
• It is not recommended to use this script in public environments unless its security is improved.

Suggested Improvements

• Store and validate passwords using hashed values.
• Restrict the types of files that can be downloaded.
• Add logging to monitor activities.
