BOSCH-SA-757244

view advisory published 2025-08-14

Several fieldbus couplers sold by Bosch Rexroth contain technology from Phoenix Contact. The manufacturer published a security bulletin about a weakness in the web-based administration interface. A successful attack leads to an overload of the device and the hardware watchdog is triggered. Process data behaves according to the configured substitute value behavior. The bus coupler requires a manual restart (resetting the power supply, pressing the reset button or executing the SNMP reset command) to reestablish communication within the Industrial Ethernet (e.g. PROFINET IO, Modbus/TCP, EtherNet/IP).
