Security News > 2023 > September > CISA warns of critical Apache RocketMQ bug exploited in attacks
The U.S. Cybersecurity and Infrastructure Security Agency has added to its catalog of known exploited vulnerabilities a critical-severity issue tracked as CVE-2023-33246 that affects Apache's RocketMQ distributed messaging and streaming platform.
CISA is warning federal agencies that they should patch the CVE-2023-33246 vulnerability for Apache RocketMQ installations on their systems by September 27.
The cybersecurity agency notes that an attacker can exploit the issue "By using the update configuration function to execute commands as the system users that RocketMQ is running."
Leveraging the issue is possible because multiple RocketMQ components that include NameServer, Broker, and Controller, are exposed on the public internet, making them a target for hackers.
Trying to find how many potential RocketMQ targets are exposed online, the researcher looked for hosts with the TCP port 9876 used by the RocketMQ Nameserver and found about 4,500 systems.
