ChirpStack SQLite Backend SQL Injection via Device Tag Key in ListDevices Filter

ChirpStack's SQLite-backend device tag filtering (chirpstack/src/storage/device.rs, in both get_count and list) interpolates the user-supplied tag KEY directly into a raw SQL fragment via Rust's format! macro , while only the tag VALUE is safely parameter-bound via Diesel's .bind.

The Kerlink firewall in ChirpStack chirpstack-mqtt-forwarder before 4.2.1 and chirpstack-gateway-bridge before 4.0.11 wrongly accepts certain TCP packets when a connection is not in the ESTABLISHED state.

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.
