Denial Of Service

Description

OpenAirInterface V2.2.0 AMF crashes when it receives an NGAP message with invalid procedure code or invalid PDU-type. For example when the message specification requires InitiatingMessage but sent with successfulOutcome.

Analysis

AMF daemon in OpenAirInterface V2.2.0 crashes upon receipt of malformed NGAP control-plane messages containing mismatched procedure codes or PDU type violations (e.g., successfulOutcome where InitiatingMessage is required). Remote attackers can trigger denial of service without authentication (CVSS AV:N/PR:N), exploiting improper input validation (CWE-20) in 5G core network signaling. …

Remediation

Within 24 hours: identify all OpenAirInterface V2.2.0 instances in production and development environments; document network exposure (particularly internet-facing or untrusted network connectivity to AMF functions). Within 7 days: evaluate OpenAirInterface upgrade path to the latest available version and test in non-production environment; implement network segmentation to restrict NGAP control-plane message sources to trusted peers only. …
