CVE-2025-70123
HighSummary
Wersja 4.0.1 free5GC zawiera podatność na niewłaściwą walidację danych wejściowych oraz zgodność z protokołem, co pozwala zdalnym atakującym na wywołanie odmowy usługi. UPF błędnie akceptuje niepoprawnie sformułowane żądanie PFCP Association Setup, co narusza standard 3GPP TS 29.244.
Risk Assessment
Podatność ta może prowadzić do stanu niespójności w UPF, co skutkuje awarią kaskadową przy próbie nawiązania sesji PFCP, zakłócając połączenie SMF i powodując degradację usług.
Recommendation
Zaleca się aktualizację do najnowszej wersji free5GC oraz wdrożenie dodatkowych mechanizmów walidacji danych wejściowych, aby zminimalizować ryzyko wystąpienia tej podatności.

Original NVD description (English source)
An improper input validation and protocol compliance vulnerability in free5GC v4.0.1 allows remote attackers to cause a denial of service. The UPF incorrectly accepts a malformed PFCP Association Setup Request, violating 3GPP TS 29.244. This places the UPF in an inconsistent state where a subsequent valid PFCP Session Establishment Request triggers a cascading failure, disrupting the SMF connection and causing service degradation.
