A vulnerability was detected in Open5GS up to 2.7.7. This affects the function gsm_build_pdu_session_establishment_accept of the file /src/smf/gsm-build.c of the component SMF. The manipulation results in denial of service. The attack can be launched 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.
AnalysisAI
Denial of service in Open5GS up to version 2.7.7 allows authenticated remote attackers to crash the Service Management Function (SMF) via manipulation of the PDU session establishment acceptance function, resulting in service unavailability. The CVSS score of 4.3 reflects low severity due to authentication requirements and availability-only impact, though publicly available exploit code exists and the vulnerability has been reported to the project without acknowledged response.
