Description

Reachable Assertion vulnerability in Open5GS up to version 2.7.6 allows attackers with connectivity to the NRF to cause a denial of service. This is achieved by sending the creation of an NF with an invalid type via SBI and then requesting its data. The NRF executes a check that crashes the process, leaving the discovery service unresponsive.

Attack-Flow Graph

Executive Summary

This vulnerability is a Reachable Assertion flaw in Open5GS up to version 2.7.5. Attackers who can connect to the NRF can cause a denial of service by creating a Network Function (NF) with an invalid type via the SBI interface and then requesting its data. The NRF performs a check that crashes the process, making the discovery service unresponsive.

Impact Analysis

The vulnerability can cause a denial of service by crashing the NRF process, which leaves the discovery service unresponsive. This disrupts the normal operation of the network functions relying on the NRF, potentially causing service outages or degraded network performance.
