Vulnerability Title
RabbitMQ MQTT Topic Permission Authorization Bypass
Vulnerability Description
RabbitMQ is a messaging and streaming broker. From 4.2.0 to before 4.2.4, RabbitMQ's MQTT plugin allows for topic-level authorization using regular expressions with variable substitution. Administrators can create patterns such as ^{client_id}-sensors$ to restrict user access to topics that include their client ID. However, the client_id is provided by the user in the MQTT CONNECT packet and is inserted into the regex pattern without escaping special regex characters. This flaw enables an authenticated MQTT user to inject regex operators to bypass authorization. This vulnerability is fixed in 4.2.4 and 4.3.0.

RabbitMQ 安全漏洞
Vulnerability Description
RabbitMQ是RabbitMQ开源的一个功能丰富的多协议消息和流媒体代理。 RabbitMQ 4.2.0至4.2.4之前版本存在安全漏洞,该漏洞源于MQTT插件中的主题级授权使用正则表达式进行变量替换,但client_id由用户提供且未转义特殊正则字符,导致认证的MQTT用户可注入正则运算符绕过授权。
