Multiple cross-site scripting (XSS) vulnerabilities in the RSComments (com_rscomments) component 1.0.0 Rev 2 for Joomla! allow remote attackers to inject arbitrary web script or HTML via the (1) website and (2) name parameters to index.php.

RSFirewall tries to identify the original IP address by looking at different HTTP headers. A bypass is possible due to the way it is implemented.

A reflected XSS vulnerability in RSform!Pro component 3.0.0 - 3.3.13 for Joomla was discovered. The issue arises from the improper handling of the filter[dateFrom] GET parameter, which is reflected unescaped in the administrative backend interface. This allows an authenticated attacker with admin or editor privileges to inject arbitrary JavaScript code by crafting a malicious URL.

A stored XSS vulnerability in RSBlog! component 1.11.6 - 1.14.4 for Joomla was discovered. The vulnerability allows authenticated users to inject malicious JavaScript into the plugin's resource. The injected payload is stored by the application and later executed when other users view the affected content.

A stored XSS vulnerability in RSMail! component 1.19.20 - 1.22.26 for Joomla was discovered. The issue occurs within the dashboard component, where user-supplied input is not properly sanitized before being stored and rendered. An attacker can inject malicious JavaScript code into text fields or other input points, which is subsequently executed in the browser of any user who clicks on the crafted text in the dashboard.
