Remote code execution via unrestricted NameServer file write
Published Jul 12, 2023 · Updated Apr 23, 2025
Code injection in Apache RocketMQ NameServer 4.9.6 and earlier and 5.0.0 through 5.1.1 allows remote attackers to execute commands. DefaultRequestProcessor.updateConfig checks the nonexistent configStorePathName key instead of configStorePath, so an unauthenticated update request can redirect and populate the configuration file at an attacker-chosen path. The NameServer must be network-reachable without permission checks; successful writes use the RocketMQ service account's filesystem rights and can establish command execution through files such as cron jobs or SSH keys.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=4.9.6
- Affected versionversion=5.0.0 <=5.1.1
