Descriptions

The affiliate-toolkit WordPress plugin before 3.4.3 lacks authorization and authentication for requests to it's affiliate-toolkit-starter/tools/atkp_imagereceiver.php endpoint, allowing unauthenticated visitors to make requests to arbitrary URL's, including RFC1918 private addresses, leading to a Server Side Request Forgery (SSRF) issue.

El complemento affiliate-toolkit de WordPress anterior a 3.4.3 carece de autorización y autenticación para solicitudes a su endpoint afiliado-toolkit-starter/tools/atkp_imagereceiver.php, lo que permite a visitantes no autenticados realizar solicitudes a URL arbitrarias, incluidas direcciones privadas RFC1918, lo que genera un problema de Server Side Request Forgery (SSRF).

The affiliate-toolkit – WordPress Affiliate Plugin plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 3.4.2 via the affiliate-toolkit-starter/tools/atkp_imagereceiver.php endpoint. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
