Description

Broadstreet Ad Widget plugin for WordPress 2.2.0 before 2.12.0 contains a local file inclusion vulnerability that allows authenticated users to execute attacker-chosen PHP files by passing unsanitized input to require in views/modal/index.php. Attackers can supply directory traversal sequences in the 'step' parameter, optionally with a null byte, to include local files and execute PHP code. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.
