The WP Hotel Booking plugin is used by hotel websites that are running on WordPress. It provides hotels with functionalities to manage room bookings and reservations online effectively. The plugin is commonly used by hotel administrators to facilitate booking management and enhance the user experience on their websites. Typically, it includes features such as availability calendars, pricing management, and booking forms. Known for its integration capabilities, it is widely adopted in the hospitality industry to streamline online reservations. This plugin sees broad usage in hotels aiming to improve their online presence and booking efficiency.
Cross-Site Scripting (XSS) is a vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. This type of attack often involves tricking users into clicking on a malicious link, which then executes harmful scripts in their web browsers. XSS vulnerabilities can lead to session hijacking, where attackers gain control of user sessions. Furthermore, attackers might also use XSS to perform attacks like defacement or phishing. The vulnerability primarily affects sites that do not properly sanitize input fields.
The Cross-Site Scripting vulnerability in the WP Hotel Booking plugin arises due to inadequate input validation in the 'check_in_date' parameter. This flaw exists in versions 2.3.2 and older, where user input is not properly sanitized. As a result, attackers can inject arbitrary JavaScript that executes when users interact with manipulated elements on a webpage. The issue is particularly critical because it doesn't require special user privileges to exploit successfully. The lack of output escaping further amplifies potential security risks and exploitation ease for attackers.
When exploited, this vulnerability can lead to various harmful effects. Attackers can hijack user sessions, gaining unauthorized access to sensitive information such as booking details. It might also result in phishing attempts where attackers present fake interfaces to collect user credentials. Furthermore, this flaw could be used in defacing hotel websites, damaging reputations and customer trust. Continuous website vulnerability could lead to a significant impact on business revenue due to a loss of customer loyalty.
