Executive Summary

This vulnerability is a security flaw found in the Hotel and Tourism Reservation System 1.0, specifically in an unknown function within the file /ht/tour.php.

It occurs when certain input arguments such as name, email, people, or number are manipulated, leading to a cross-site scripting (XSS) vulnerability.

This means an attacker can inject malicious scripts remotely through these input fields, potentially affecting users who interact with the system.

Impact Analysis

The vulnerability allows remote attackers to perform cross-site scripting attacks by manipulating input parameters.

Such attacks can lead to the execution of malicious scripts in the context of users' browsers, potentially resulting in session hijacking, defacement, or redirection to malicious sites.

Because the exploit is publicly available, the risk of attacks exploiting this vulnerability is increased.

Compliance Impact

The vulnerability is a Stored Cross-Site Scripting (XSS) flaw that allows attackers to inject malicious scripts into booking form fields, which can lead to session hijacking, credential theft, or full admin account takeover.

Such security issues can impact compliance with common standards and regulations like GDPR and HIPAA because they may lead to unauthorized access to sensitive personal data or administrative controls.

Specifically, failure to properly sanitize and encode user input can result in data breaches or unauthorized data manipulation, which are violations of data protection requirements under these regulations.

Therefore, this vulnerability could potentially cause non-compliance with standards that mandate protection of personal data and secure system access.

Detection Guidance

This vulnerability can be detected by testing the /ht/tour.php endpoint for injection of malicious JavaScript payloads into the parameters name, email, people, and contact. An unauthenticated attacker can inject scripts into these fields which are stored in the database and later executed in the admin panel.

To detect the vulnerability, you can attempt to submit a booking form with a simple XSS payload such as <script>alert(1)</script> in the mentioned parameters and then verify if the payload is executed when viewing the /ht/admin/tour_reserves.php page.

Example commands using curl to test injection might be:

• curl -X POST -d "name=<script>alert(1)</script>&[email protected]&people=1&contact=1234567890" https://targetsite.com/ht/tour.php
• Then, access the admin page /ht/admin/tour_reserves.php to check if the script executes.

Mitigation Strategies

Immediate mitigation involves sanitizing and encoding user inputs and outputs to prevent malicious scripts from being stored and executed.

Specifically, the recommended fix is to apply output encoding using htmlspecialchars or a similar function before rendering user-supplied data on the admin panel page /ht/admin/tour_reserves.php.

Additionally, input validation and sanitization should be implemented on the booking form fields (name, email, people, contact) to block or neutralize malicious payloads.

Until a patch is applied, consider restricting access to the admin panel and monitoring logs for suspicious input patterns.
