CVE-2023-4110 Scanner Detail

The PHPJabbers Availability Booking Calendar is a versatile software solution used primarily by hospitality businesses like hotels, rental services, and event planners to manage bookings and availability online. It integrates seamlessly into existing websites, providing an intuitive interface for both business owners and customers. This calendar application allows users to customize booking forms, manage reservations, set availability, and process payments, making it an essential tool for businesses looking to streamline their booking processes and enhance customer service.

The detected vulnerability involves a Cross-Site Scripting (XSS) issue within the PHPJabbers Availability Booking Calendar. XSS vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users, leading to unauthorized access to user sessions and sensitive information. This specific issue arises due to improper validation of user-supplied input in the 'session_id' parameter, making it possible for attackers to execute arbitrary web scripts in the context of the user's browser session.

The vulnerability exists within the '/index.php' file, where the 'session_id' parameter fails to properly sanitize input before incorporating it into the output it generates. By crafting a malicious URL containing a script in the 'session_id' parameter, an attacker can trigger the vulnerability, leading to the execution of the script whenever a user visits the manipulated URL. This flaw can result in unauthorized actions being performed on behalf of the user, theft of session cookies, and other potentially damaging outcomes.

If exploited, the XSS vulnerability in the PHPJabbers Availability Booking Calendar could lead to several adverse effects, including theft of user credentials, hijacking of user sessions, redirecting users to malicious sites, and the execution of unwanted actions in the context of the user's session. This can severely compromise user privacy and security, erode trust in the affected platform, and potentially expose the platform to further attacks.
