Description

Ella Core has a UE Security Capability bypass on NGAP PathSwitchRequest

Summary

Ella Core does not verify the UE Security Capabilities received in NGAP PathSwitchRequest messages against its locally stored values. A malicious gNB can overwrite Ella Core's stored UE security capabilities for any UE with arbitrary values by sending a single crafted PathSwitchRequest.

Impact

A gNB can corrupt Ella Core's stored UE security capabilities for a target UE.

Fix

The PathSwitchRequest handler now compares the received UE Security Capabilities against Ella Core's locally stored values, preserves the stored values on mismatch, returns them in the PathSwitchRequestAcknowledge, and logs the event.

This issue can be reached from an adjacent network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required.
