A flaw has been found in Open5GS up to 2.7.6. This impacts the function ogs_sbi_nf_instance_set_id in the library /lib/sbi/context.c of the component NRF. Executing a manipulation of the argument nfInstanceId can lead to denial of service. The attack may be performed from remote. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.
