Technical Details

what runs on :38462

E1AP (E1 Application Protocol) runs over SCTP on port 38462 and carries control signaling between the gNB-CU-CP and gNB-CU-UP, including procedures for setting up, modifying, and releasing bearer contexts. SCTP establishes an association using its INIT/INIT ACK and cookie handshake; E1AP messages use ASN.1 encoding. SCTP and E1AP do not encrypt the traffic by themselves, so protection depends on the deployment's transport-network security.

security overview

E1 is an internal radio-access-network control interface and should not be exposed to the public internet. An reachable endpoint could be probed for SCTP/E1AP behavior, and access to signaling could threaten bearer and service availability; restrict peers and protect the transport network, using IPsec where required by the deployment. The protocol stack itself does not provide encryption.

Record

iana registry entry

port: :38462
service: 5G E1 Interface (E1AP)
transport: SCTP
encryption: cleartext
assignment: iana registered
risk: 6/10risk
category: Network Services Mobile
usage: This port carries E1AP signaling between the control-plane and user-plane components of a 5G gNB. Engineers are most likely to encounter it on internal network paths between telecom equipment, not as a general-purpose internet service. The IANA assignment is held by Huawei Technologies France, but E1 is a 3GPP interface rather than a Huawei-only protocol.
