Joomla Solidres Cross-Site Scripting Scanner

Joomla Solidres is a popular extension used within Joomla content management systems, primarily for hotel and room booking. It is employed by hotels, resorts, hostels, and travel agencies to manage reservations and bookings efficiently. Users utilize Solidres to create a seamless booking experience, manage resources effectively, and improve customer satisfaction. The integration with Joomla allows for extensive customization and easy management, making it ideal for businesses seeking comprehensive booking solutions. As third-party software for Joomla, it extends the functionalities of the core CMS to include advanced booking features. Widely used across various businesses due to its robust suite of features, it plays a crucial role in operations reliant on reservations.

Cross-Site Scripting (XSS) in Joomla Solidres involves injecting malicious scripts into vulnerable parameters within the software. This vulnerability is notably found in the 'show' GET parameter of the Joomla Solidres extension. It allows attackers to execute arbitrary scripts within the trusted context of reported affected endpoints. Successful exploitation of this vulnerability can lead to unauthorized actions executed on behalf of legitimate users. Malicious scripts can potentially gather user information or perform actions masked as the affected user. XSS vulnerabilities like this can compromise both user data and application integrity.

The technical roots of this vulnerability can be traced to the lack of proper input sanitation on parameters that Solidres regularly processes. The 'show' parameter, in particular, fails to strip or sanitize input users provide, thus allowing the injection of arbitrary JavaScript code. Attackers can exploit this by appending script code to this parameter, which then executes in the user's browser. The inclusion of unsanitized characters within certain input fields can manipulate the dynamic content display, leading to vulnerabilities. The described scenario requires modifying URL endpoints to include scripts executed upon page load. This lack of sanitation provides a route for attackers to introduce and execute scripts undetected.

If exploited, this XSS vulnerability can lead to significant security ramifications. Malicious individuals may execute unauthorized actions mimicking legitimate users, thus circumventing access controls. Private user data might be exposed or modified without consent, leading to trust degradation and potential legal implications. Furthermore, attackers could distribute harmful payloads or collect critical data stealthily. This can also disrupt normal application operations, leading to a denial of service. The exploitation could result in broader security incidents involving the infrastructure linked to the affected software.
