This paper introduces a novel Wireshark dissector designed to facilitate the analysis of Service-Based Interface (SBI) communication in 5G Core Networks. Our approach involves parsing the OpenAPI schemes provided by the 5G specification to automatically generate the dissector code. Our tool enables the validation of 5G Core Network traces to ensure compliance with the specifications. Through testing against three open-source 5G Core Network projects, we identified several issues where messages deviate from specification standards, highlighting the significance of our implementation in ensuring protocol conformity and network reliability.
