vulnerability analysis and mitigation
Overview
An issue in Free5gc v.3.3.0 allows a local attacker to cause a denial of service via the free5gc-compose component. The vulnerability was discovered and assigned CVE-2023-47025 in November 2023 (NVD, MITRE).
Technical details
The vulnerability is classified with CWE-400 (Uncontrolled Resource Consumption) and has received a CVSS v3.1 base score of 5.5 (MEDIUM) with the vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H. The issue manifests when the AMF (Access and Mobility Management Function) component fails to properly handle NGAP messages, resulting in a null pointer dereference that crashes the service (GitHub Issue).
Impact
When exploited, this vulnerability causes the AMF component to crash, leading to a denial of service condition that affects not only the targeted connection but also disrupts service for other connected UEs (User Equipment). This can result in a complete service outage for all users connected to the affected AMF instance (GitHub Issue).
Mitigation and workarounds
The vulnerability affects Free5gc version 3.3.0. Users should upgrade to a newer version when available. No specific workarounds have been publicly documented (FortiGuard).
