A security flaw has been discovered in Open5GS up to 2.7.7. This issue affects the function smf_nsmf_handle_update_data_in_vsmf of the file /src/smf/nsmf-handler.c of the component SMF. The manipulation results in denial of service. The attack can be executed remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Denial of service in Open5GS through version 2.7.7 allows authenticated remote attackers to crash the Service Management Function (SMF) by manipulating the smf_nsmf_handle_update_data_in_vsmf function in nsmf-handler.c. Publicly available exploit code exists, and the project maintainers have not yet responded to the early disclosure notification despite awareness of the issue.
