Apache RocketMQ Command Execution Vulnerability

Apache · RocketMQ

CVSS 9.8 EPSS 97% no public exploit indexed Fix deadline passed 27 September 2023

What it is

Several components of Apache RocketMQ, including NameServer, Broker, and Controller, are exposed to 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 or achieve the same effect by forging the RocketMQ protocol content.

Why we say that

  • EPSS puts exploitation in the next 30 days at 97%
  • CISA's federal remediation deadline (2023-09-27) has passed
  • CVSS 9.8 critical
  • Listed in the CISA Known Exploited Vulnerabilities catalogue

Every line above comes from a named public source. Where the evidence is thin, we say so rather than inventing confidence — see methodology.

What to do

Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.

What it costs when this goes wrong

This is where UK enforcement meets the vulnerability record. Where an unfixed vulnerability leads to a breach, the ICO treats it as a security failure under UK GDPR. Recent cases:
