External Control of File Name or Path

Summary

The BookingPress – Appointment Booking Calendar Plugin and Online Scheduling Plugin plugin for WordPress is vulnerable to Arbitrary File Read to Arbitrary File Creation in all versions up to, and including, 1.1.5 via the 'bookingpress_save_lite_wizard_settings_func' function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create arbitrary files that contain the content of files (either on the local server or from a remote location), allowing the execution of any PHP code in those files or the exposure of sensitive information.
