Vulnerability Title
NULL Pointer Dereference in REST API properties_parse via Malformed user_properties
Vulnerability Description
In nanomq versions 0.24.11 and earlier, a NULL pointer dereference in `properties_parse()` allows an authenticated attacker to crash the NanoMQ broker by sending a POST request to `/api/v4/mqtt/publish` with `user_properties` as a JSON array instead of a JSON object. The crash occurs because `strlen()` is called on a NULL `item->string` pointer when iterating over array elements. An authenticated attacker can exploit this to crash the NanoMQ broker process. This is patched in version 0.24.14.

NanoMQ 异常处理不当漏洞
Vulnerability Description
nanomq nanomq是nanomq的消息队列中间件。 NanoMQ 0.24.11及之前版本存在异常处理不当漏洞,该漏洞源于properties_parse()函数中存在空指针取消引用,当向/api/v4/mqtt/publish发送带有user_properties为JSON数组而非JSON对象的POST请求时,strlen()被调用在一个NULL的item->string指针上,导致NanoMQ代理崩溃。
