CVE-2025-66023 (CNNVD-202601-028)
中文标题:
NanoMQ 资源管理错误漏洞
英文标题:
NanoMQ has Use-After-Free of malformed bridging message
漏洞描述
中文描述:
NanoMQ是美国EMQ开源的一款用于物联网边缘平台的轻量级快速 MQTT Broker。 NanoMQ 0.24.5之前版本存在资源管理错误漏洞，该漏洞源于MQTT桥接客户端组件存在堆释放后重用，可能导致服务崩溃或内存损坏。
英文描述:
NanoMQ MQTT Broker (NanoMQ) is an all-around Edge Messaging Platform. Versions prior to 0.24.5 have a Heap-Use-After-Free (UAF) vulnerability within the MQTT bridge client component (implemented via the underlying NanoNNG library). The vulnerability is triggered when NanoMQ acts as a bridge connecting to a remote MQTT broker. A malicious remote broker can trigger a crash (Denial of Service) or potential memory corruption by accepting the connection and immediately sending a malformed packet sequence. Version 0.34.5 contains a patch. The patch enforces stricter protocol adherence in the MQTT client SDK embedded in NanoMQ. Specifically, it ensures that CONNACK is always the first packet processed in the line. This prevents the state confusion that led to the Heap-Use-After-Free (UAF) when a malicious server sent a malformed packet sequence immediately after connection establishment. As a workaround, validate the remote broker before bridging.
