CVE-2023-33246
Description
For RocketMQ versions 5.1.0 and below, under certain conditions, there is a risk of remote command execution.
Several components of RocketMQ, including NameServer, Broker, and Controller, are leaked on the extranet and lack permission verification, an attacker can exploit this vulnerability by using the update configuration function to execute commands as the system users that RocketMQ is running as. Additionally, an attacker can achieve the same effect by forging the RocketMQ protocol content.
To prevent these attacks, users are recommended to upgrade to version 5.1.1 or above for using RocketMQ 5.x or 4.9.6 or above for using RocketMQ 4.x .
Summary dbcve.org
RocketMQ versions 5.1.0 and below expose NameServer, Broker, and Controller components on the network without permission verification. An unauthenticated remote attacker can either invoke the update configuration function or forge RocketMQ protocol content to achieve remote command execution as the user running the RocketMQ processes.
Mitigation
Upgrade RocketMQ to version 5.1.1 or later on the 5.x branch, or 4.9.6 or later on the 4.x branch, and ensure Broker/NameServer/Controller ports are not unnecessarily exposed to untrusted networks.
