Detailsinfo

A vulnerability classified as problematic was found in realmag777 TableOn Plugin up to 1.0.4.4 on WordPress. Affected by this vulnerability is the function do_shortcode_button of the component Shortcode Handler. The manipulation of the argument class/help_link/popup_title/help_title with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. As an impact it is known to affect integrity. The summary by CVE is:

The TableOn – WordPress Posts Table Filterable plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tableon_button' shortcode in all versions up to and including 1.0.4.4. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'class', 'help_link', 'popup_title', and 'help_title'. The do_shortcode_button() function extracts these attributes without sanitization and passes them to TABLEON_HELPER::draw_html_item(), which concatenates attribute values into HTML using single quotes without escaping (line 29: $item .= " {$key}='{$value}'"). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
