Vulnerabilidades do Brainstorm Force SureDash – Community, Courses & Member Dashboard

The SureDash – Community, Courses & Member Dashboard plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'display_name' parameter in all versions up to, and including, 1.12.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit is triggered when any user hovers over a comment's like counter on a community page, as the plugin's tooltip handler assigns the attacker-controlled data-tooltip-description attribute value directly to innerHTML, re-parsing the browser-decoded entity payload as live HTML.

The SureDash – Community, Courses & Member Dashboard plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via Image 'alt' Attribute in Community Post Content in all versions up to, and including, 1.12.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The entity-encoded payload bypasses server-side wp_kses filtering because kses permits the img/alt tag combination and does not normalize entities inside attribute values; the decode occurs client-side when GLightbox reads the .alt DOM property and assigns the result to innerHTML.

The SureDash – Community, Courses & Member Dashboard plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'draweropenverposition' Block/Shortcode Attribute in all versions up to, and including, 1.10.3 due to insufficient input sanitization and output escaping. 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. The injected payload is stored inside the block-delimiter HTML comment's JSON, which wp_kses_post does not neutralize on save, and is only interpolated into the rendered style attribute at display time without esc_attr() escaping, allowing a double-quote to break out of the attribute and introduce arbitrary HTML event handlers.

The SureDash – Community, Courses & Member Dashboard plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Shortcode Attributes in all versions up to, and including, 1.10.0 due to insufficient input sanitization and output escaping. 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.
