Description
The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to Remote Code Execution in versions 3.14.10 through 3.15.1. This is due to missing neutralization of shortcode brackets in the system_ip and referer_url merge tag sources in both MergeTags/Other.php and MergeTags/Deprecated.php before their values are processed by do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes registered on the site by supplying crafted bracket sequences in request-derived merge tag values such as the client IP address or referer URL.
