Improperly Implemented Security Check for Standard

Overview Affected versions of this package are vulnerable to Improperly Implemented Security Check for Standard due to missing concurrent procedure validation in the SecurityMode and handleHandoverRequiredMain functions. An attacker can cause mismatches between security contexts, potentially...

Free5GC AMF has Missing Concurrent NAS SMC Validation During NGAP Handover

Summary The AMF in Free5GC v4.2.1 does not enforce the concurrent security procedure rules defined in 3GPP TS 33.501 §6.9.5.1. The AMF does not check for ongoing N2 handover procedures before initiating a NAS Security Mode Command, and vice versa. This can lead to mismatches between NAS and AS...
