A weakness has been identified in Open5GS up to 2.7.7. Affected is the function ogs_id_get_value of the file /src/amf/nudm-handler.c of the component AMF. This manipulation causes denial of service. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
