What to do

Update, patch or deactivate.

Update Switch CTA Box to a release after 1.1, or disable and remove it until a fixed version is available.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

The Switch CTA Box plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wppw_cta_box' shortcode in all versions up to, and including, 1.1. This is due to insufficient input sanitization and output escaping on user-supplied post meta values including 'cta_box_button_link', 'cta_box_button_id', 'cta_box_button_text', and 'cta_box_description'. The shortcode reads post meta from a user-specified post ID and echoes these values directly into HTML output without any escaping functions (no esc_attr(), esc_url(), or esc_html()). 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.
