Description
A vulnerability was detected in Open5GS up to 2.7.7. This affects an unknown function in the library /lib/sbi/message.c of the component NRF. Performing a manipulation of the argument service-names/snssais results in denial of service. The attack is possible to be carried out remotely. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
A denial-of-service vulnerability has been identified in Open5GS versions through 2.7.7, specifically within the NRF component. The issue arises in the library '/lib/sbi/message.c', where an unknown function fails to properly handle oversized 'service-names' in discovery queries. This oversight allows for remote exploitation, causing the NRF process to crash. The vulnerability has been publicly disclosed, and although the project was notified earlier, no response has been made.
