Summary

Ella Core is a 5G core designed for private networks. Prior to 1.10.0, 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. This vulnerability is fixed in 1.10.0.
