Unauthenticated information disclosure via unprotected HTTP endpoint

Published Oct 3, 2023 · Updated Sep 19, 2024

Missing authentication in Open5GS 2.4.10 and earlier allows remote attackers to retrieve stored device information via HTTP. INCIBE identifies an unprotected Open5GS endpoint but has not disclosed its path, handler, or the request processing that omits authentication. No credentials or user interaction are required; the published impact is limited to reading stored information and possible service interruption.
