A vulnerability was determined in Open5GS up to 2.7.7. This vulnerability affects the function bsf_sess_add_by_ip_address of the file /nbsf-management/v1/pcfBindings of the component BSF. Executing a manipulation of the argument ipv4Addr can lead to denial of service. The attack can be launched remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Denial of service in Open5GS up to version 2.7.7 allows remote unauthenticated attackers to crash the BSF (Binding Support Function) service by manipulating the ipv4Addr parameter in the /nbsf-management/v1/pcfBindings endpoint. The vulnerability has publicly available exploit code and affects a core 5G network function, creating operational risk for mobile networks relying on this open-source implementation.
