CVE-2026-33282
HighSummary
Ella Core to rdzeń 5G zaprojektowany dla prywatnych sieci. Wersje przed 1.6.0 powodują awarię podczas przetwarzania źle sformatowanej wiadomości NGAP LocationReport z typem zdarzenia `ue-presence-in-area-of-interest`, gdy opcjonalny element `UEPresenceInAreaOfInterestList` jest pominięty.
Risk Assessment
Atakujący, który potrafi wysłać spreparowane wiadomości NGAP do Ella Core, może spowodować awarię procesu, co prowadzi do zakłócenia usług dla wszystkich podłączonych subskrybentów. Nie jest wymagane uwierzytelnienie.
Recommendation
Zaleca się aktualizację do wersji 1.6.0 lub nowszej, która wprowadza weryfikację obecności elementu w obsłudze wiadomości NGAP.

Original NVD description (English source)
Ella Core is a 5G core designed for private networks. Versions prior to 1.6.0 panic when processing a malformed NGAP LocationReport message with `ue-presence-in-area-of-interest` event type and omitting the optional `UEPresenceInAreaOfInterestList` IE. An attacker able to send crafted NGAP messages to Ella Core can crash the process, causing service disruption for all connected subscribers. No authentication is required. Version 1.6.0 added IE presence verification to NGAP message handling.
