CVE-2026-30079: n/a
In OpenAirInterface V2.2.0 AMF, Out of sequence messages causes incorrect state transition during UE registration procedure. This allows authentication to be bypassed completely. If a SecurityModeComplete message is sent after InitialUERegistration, a registration reject is received followed by a registration accept! This leads the UE to be registered without proper authentication.
AI Analysis
Technical Summary
This vulnerability in OpenAirInterface V2.2.0 AMF involves improper handling of out-of-sequence messages during the UE registration process. The flaw allows an attacker to bypass authentication by exploiting the state machine's incorrect transitions triggered when a SecurityModeComplete message is sent after InitialUERegistration. This leads to the UE being registered despite the authentication procedure not completing correctly.
Potential Impact
The impact is that an attacker can bypass the authentication mechanism during UE registration, potentially allowing unauthorized devices to register on the network. This undermines the security of the authentication process and could lead to unauthorized network access or other downstream security issues related to unauthorized UE registration.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation is currently documented. Until a patch is available, monitoring vendor communications for updates is recommended.
