Exploitation Status

No confirmed exploitation observed yet

  • CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
  • A successful exploit gives an attacker total control of the affected component, not partial access.
  • CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Description

The RocketMQ NameServer component still has a remote command execution vulnerability as the CVE-2023-33246 issue was not completely fixed in version 5.1.1.

When NameServer address are leaked on the extranet and lack permission verification, an attacker can exploit this vulnerability by using the update configuration function on the NameServer component to execute commands as the system users that RocketMQ is running as.

It is recommended for users to upgrade their NameServer version to 5.1.2 or above for RocketMQ 5.x or 4.9.7 or above for RocketMQ 4.x to prevent these attacks.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.rocketmq:rocketmq-namesrv, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.apache.rocketmq:rocketmq-namesrv to 4.9.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-37582 is resolved across your whole dependency graph.

  3. Workarounds

    Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
