CVE-2020-28349 (GCVE-0-2020-28349)

Vulnerability from cvelistv5 – Published: 2020-11-09 00:54 – Updated: 2024-08-04 16:33 Disputed

Summary

An inaccurate frame deduplication process in ChirpStack Network Server 3.9.0 allows a malicious gateway to perform uplink Denial of Service via malformed frequency attributes in CollectAndCallOnceCollect in internal/uplink/collect.go. NOTE: the vendor's position is that there are no "guarantees that allowing untrusted LoRa gateways to the network should still result in a secure network.
