Name of the Vulnerable Software and Affected Versions Ella Core versions prior to 1.10.0

Description A radio with a valid NG Setup can send a forged 'PDUSessionResourceSetupResponse' carrying any UE's AMF-UE-NGAP-ID. The software fails to verify if the message arrived on the SCTP association bound to the logical NG-connection of that UE, subsequently creating a GTP tunnel towards the radio. This results in the redirection of downlink user-plane traffic for the targeted UE to the attacker's radio.

Recommendations Update to version 1.10.0.
