TinyBrowser is typically bundled with web applications, such as TinyMCE WYSIWYG content editor or the Joomla! content management system, although it can also be used in its standalone configuration or integrated with other custom web applications. The version of the TinyBrowser component running on the remote host is affected by multiple cross-site scripting (XSS) vulnerability in /tinybrowser/upload.php due to improper sanitization of user-supplied input to the 'goodfiles', 'badfiles' and 'dupfiles' parameters before using it to generate dynamic HTML content. An unauthenticated, remote attacker can exploit these to inject arbitrary HTML and script code into the user's browser session. Note that this version of TinyBrowser may be affected by several other vulnerabilities that allow an unauthenticated user to view, upload, delete, and rename files and folders on the affected host, or to launch cross-site request forgery attacks using the application.
