BookingPress Appointment Booking <= 1.1.5 - Authenticated (Subscriber+) Arbitrary File Read to Arbitrary File Creation

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.

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Appointment Booking Calendar Plugin and Scheduling Plugin 1.1.6 closes this, and updating the plugin is the step that ends it.
