HIGH7.1EPSS 0.02%Ella Core Vulnerable to UE Downlink Redirection via Forged PDUSessionResourceSetupResponse
發布日:2026/5/11修改日:2026/5/11
描述
## Summary A radio with a valid NG Setup can send a forged PDUSessionResourceSetupResponse carrying any UE's AMF-UE-NGAP-ID. Ella Core does not verify the message arrived on the SCTP association bound to that UE's logical NG-connection, then creates a GTP tunnel towards that radio. ## Impact Downlink user-plane traffic for the targeted UE is redirected to the attacker's radio. ## Fix UE context lookups are now scoped to the sending radio's SCTP association.
