AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions omec-project UPF versions up to 2.1.3-dev

Description A flaw exists in the omec-project UPF (pfcpiface component) that can lead to a denial-of-service condition. Specifically, a crafted PFCP Session Establishment Request, containing a malformed Flow-Description, is not adequately validated. The parseFlowDesc function can read beyond the allocated buffer, resulting in a process termination. An attacker capable of sending PFCP Session Establishment Request messages to the UPF’s N4/PFCP endpoint can exploit this to repeatedly crash the UPF process. The vulnerable component is the pfcpiface component.

Recommendations Update to a version beyond 2.1.3-dev.
