Unauthenticated file disclosure via unchecked GET parameter

Published Mar 28, 2023 · Updated Jan 16, 2025

Arbitrary file disclosure in Osprey Pump Controller 1.01 allows remote attackers to read sensitive device files via HTTP GET requests. The web interface accepts attacker-chosen file references in the eventFileSelected GET parameter and returns the referenced file without authentication. Network access to the controller's web interface is sufficient; disclosed files can reveal sensitive configuration and system information.
