MODBUS service interruption via crafted packet resource leak
Published Jun 26, 2023 · Updated Dec 5, 2024
Uncontrolled resource consumption in WAGO Series 750-3x/-8x through FW10 allows remote attackers to interrupt the MODBUS server. Specially crafted MODBUS packets cause the server to retain a resource after its effective lifetime; the vendor has not disclosed the resource or packet field involved. No authentication or user interaction is required, and the documented consequence is limited to loss of MODBUS service availability.
