3Description
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.
Analysis
Stored Cross-Site Scripting in TableOn - WordPress Posts Table Filterable plugin versions up to 1.0.4.4 allows authenticated attackers with Contributor-level access or above to inject arbitrary JavaScript via unescaped shortcode attributes ('class', 'help_link', 'popup_title', 'help_title') in the 'tableon_button' shortcode. The vulnerability results from the do_shortcode_button() function extracting attributes without sanitization and the TABLEON_HELPER::draw_html_item() function concatenating these values directly into HTML output without escaping, enabling malicious scripts to execute in the browsers of users viewing affected pages. …
