The open fronthaul interface defined by O-RAN ALLIANCE aims to support the interoperability between multi-vendor open radio access network (O-RAN) radio units (O-RU) and O-RAN distributed units (O-DU). This paper introduces a new tool that could be used to evaluate Denial-of-Service (DoS) attacks against the open fronthaul interface. We launched an array of control/user planes (C/U-Planes) attacks with the tool under different traffic types and data rates, and we evaluated their impacts on the throughput and block error rate (BLER) of real-world O-RAN systems with commercial hardware.
