divisupreme vulnerabilities and threats

The Supreme Modules Lite plugin for WordPress is vulnerable to arbitrary file upload in all versions up to, and including, 2.5.62. This is due to insufficient file type validation detecting JSON files, allowing double extension files to bypass sanitization while being accepted as a valid JSON file. This makes it possible for authenticated attackers, with author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

The Supreme Modules Lite – Divi Theme, Extra Theme and Divi Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘button_one_id’ parameter in all versions up to, and including, 2.5.51 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 Supreme Modules Lite – Divi Theme, Extra Theme and Divi Builder plugin for WordPress is vulnerable to DOM-Based Cross-Site Scripting via the ‘typing_cursor’ parameter in versions up to, and including, 2.5.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
