The BeeTeam368 Extensions plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.3.4 via the handle_remove_temp_file() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to perform actions on files outside of the originally intended directory. This vulnerability can be used to delete the wp-config.php file, which can be leveraged into a site takeover.
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as “/abs/path” that can resolve to a location that is outside of that directory.
