Summary

A denial-of-service vulnerability exists in the omec-project UPF (pfcpiface component) version 2.1.3-dev. After PFCP association, a specially crafted PFCP Session Establishment Request with a CreatePDR containing a malformed Flow-Description is not robustly validated; the parseFlowDesc parser can read beyond the buffer, causing a panic and terminating the UPF process.

Risk Assessment

An attacker able to send PFCP messages to the UPF's N4/PFCP endpoint can repeatedly crash the UPF and disrupt user-plane services.

Recommendation

Update omec-project UPF to a version that validates Flow-Description, and restrict access to the N4/PFCP endpoint to trusted sources.

Original NVD description (English source)

A denial-of-service vulnerability exists in the omec-project UPF (pfcpiface component) in version upf-epc-pfcpiface:2.1.3-dev. After PFCP association, a specially crafted PFCP Session Establishment Request with a CreatePDR that contains a malformed Flow-Description is not robustly validated. The Flow-Description parser (parseFlowDesc) can read beyond the bounds of the provided buffer, causing a panic and terminating the UPF process. An attacker who can send PFCP Session Establishment Request messages to the UPF's N4/PFCP endpoint can exploit this issue to repeatedly crash the UPF.
