CVE-2026-33282 Details
Description
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.
A denial-of-service vulnerability has been identified in Ella Core versions prior to 1.6.0. The issue arises when the software processes a malformed NGAP LocationReport message that includes the 'ue-presence-in-area-of-interest' event type but omits the optional 'UEPresenceInAreaOfInterestList' information element. This flaw can be exploited by an attacker who sends crafted NGAP messages to Ella Core, causing the application to crash and disrupting service for all connected subscribers. Notably, no authentication is required to exploit this vulnerability.
Users can upgrade to Ella Core version 1.6.0 or later, where this vulnerability has been patched by adding verification for the presence of the information element in NGAP message handling.
