WP-BusinessDirectory vulnerabilities

The WP-BusinessDirectory WordPress plugin through 4.0.2 does not restrict the type or destination of files saved by an unauthenticated upload handler, allowing unauthenticated attackers to write files with arbitrary content to arbitrary locations, though not to execute code on a default server configuration.

The WP-BusinessDirectory plugin for WordPress up to version 4.0.1 contains an unauthenticated arbitrary file deletion vulnerability. Insufficient path validation in the remove() method of the JBusinessDirectoryControllerUpload class allows an attacker to manipulate the _filename parameter and delete critical server files.

In WP-BusinessDirectory versions <= 4.0.0, there is a vulnerability that allows subscribers to upload arbitrary files.
