Published Mar 28, 2023 · Updated Jan 16, 2025

Hardcoded credentials in ProPump & Controls, Inc. Osprey Pump Controller 1.01 allow remote attackers full administrative web-interface access. The firmware provisions a concealed administrative user with an immutable password and omits the account from the normal credential-management menu. Network access to the management interface is sufficient to authenticate with those credentials and read or alter controller configuration.
