[+] This HTML page is designed to remotely upload PHP malicious files directly.

[+] Here’s a breakdown of its components and functionality:

HTML Structure:  
    DOCTYPE & <html>: Defines the document type and language.  
    <head>: Contains meta-information about the document like character encoding and viewport settings, and the title of the page.  
    <body>: Contains the main content of the page.

Form Elements:  
    <form id="uploadForm">: A form with the ID "uploadForm" that contains input fields and a button for file upload.  
    <label> and <input> fields: Collect information from the user:  
        Target IP: IP address where the file will be uploaded.  
        Attacker IP: The IP address of the attacker (though this field is not used in the script).  
        Attacker Port: The port number of the attacker (not used in the script).  
        File Input: Allows the user to select a file to upload.  
    <button>: A button that triggers the file upload process when clicked.

JavaScript Functionality:  
    uploadFile(): Function executed when the "Upload File" button is clicked.  
        Collects input values: Retrieves values from the input fields and the selected file.  
        Validation: Checks if all fields are filled and a file is selected. Alerts the user if any field is missing.  
        FormData Object: Creates a FormData object to package the file and additional data (name with the value 'PWNED').  
        fetch API: Sends a POST request to the target IP with the file attached:  
            URL: http://${targetIP}/banking/classes/SystemSettings.php?f=update_settings  
            Response Handling: Logs success or failure based on the server's response. If the response is '1', it indicates success; otherwise, it logs an error.

Security Note:  
    Potential Risk: This script is for educational purposes, and its functionality (uploading a file to a specified server) could be misused.   
It’s crucial to ensure that any file upload functionality is properly secured and validated to prevent unauthorized access or attacks.

[+] Choose the target IP .

[+] Put any IP address of your own .

[+] Put any port .

[+] The path to upload the files : http://localhost/banking/uploads/
