A vulnerability has been discovered in the Movie Ticket Booking System, specifically in the editBooking.php file. The vulnerability has been classified as problematic and poses a significant risk as it allows a remote attacker to launch a cross site scripting (XSS) attack. This particular CVE identifier, CVE-2022-4251, corresponds to a vulnerability with the ID VDB-214628.

Description of the Vulnerability

The vulnerability resides in some unknown functionality of the editBooking.php file of the Movie Ticket Booking System. By exploiting this vulnerability, an attacker can execute arbitrary code in the context of the user's browser, steal sensitive information, or redirect users to malicious websites without their consent.

Cross site scripting vulnerabilities can occur when an application includes untrusted data in a web page without proper validation or escaping. In this case, the vulnerability is caused by the improper handling of user input in the editBooking.php file.

Exploitation Details

A remote attacker can exploit this vulnerability by sending a specially crafted HTTP request containing malicious JavaScript code. When the victim user loads the vulnerable page, the malicious code will be executed in their browser. The attacker can then perform various actions on behalf of the victim user, such as stealing their authentication cookies or redirecting them to a malicious website.

The following code snippet demonstrates how an attacker might craft the malicious HTTP request

// Malicious payload
let payload = "<script>alert(document.cookie);</script>";

// Sending the payload as part of an HTTP request
fetch("http://example.com/editBooking.php";, {
  method: "POST",
  headers: {
    "Content-Type": "application/x-www-form-urlencoded"
  },
  body: booking_id=${payload}
})
  .then((response) => {
    console.log("Request succeeded:", response);
  })
  .catch((error) => {
    console.error("Request failed:", error);
  });
