CVE-2023-48319: Improper Privilege Management Vulnerability in Salon Booking System Leads to Privilege Escalation

If you're using the Salon Booking System to manage your appointment scheduling, be aware that there might be a significant security issue that could potentially affect your business. This post covers the CVE-2023-48319 vulnerability, discovered in versions before 8.6, which allows privilege escalation due to improper privilege management. We'll dive into the details of the exploit, provide you with code snippets related to the vulnerability, and link to original references for further information.

Exploit Details

The vulnerability CVE-2023-48319, found in the Salon Booking System up to version 8.6, leads to privilege escalation due to improper privilege management. This can be exploited by an attacker who gains unauthorized access to your system, potentially leading to full control of your salon booking application. The vulnerability arises from an issue where everything from booking confirmations to managing roles relies on insufficient verification. As a result, an attacker can potentially manipulate the data and perform actions as an administrator without proper authorization.

Here's a code snippet linked with the vulnerability

add_action( 'wp_ajax_sb_accept_booking', 'accept_booking' );

function accept_booking() {
    $booking_id = (int) $_POST['id'];
    $response = $this->acceptBooking( $booking_id );

    if ( $response ) {
        wp_send_json_success();
    } else {
        wp_send_json_error();
    }
}

As you can see from the above code, there's no proper validation or authorization check before allowing the action to be performed. This leaves your salon booking system wide open for an attacker to exploit.
