Known exploited vulnerability
CVE-2023-33246
The short answer
CVE-2023-33246 affects Apache Software Foundation Apache RocketMQ and is rated critical (CVSS 9.8). CISA added it to the Known Exploited Vulnerabilities catalog on 2023-09-06: attackers are using it, so patch it first. Fixed versions are published for rocketmq-broker (5.1.1) and rocketmq-namesrv (4.9.6, 5.1.1).
What it is
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 .
Weakness: CWE-94.
