CVE-2023-37582
Published: 12 July 2023
Summary
CVE-2023-37582 is a critical-severity Code Injection (CWE-94) vulnerability in Apache Rocketmq. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 0.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability is an incomplete remediation of a prior remote code execution issue (CVE-2023-33246) that persists in the RocketMQ NameServer component through version 5.1.1. When NameServer addresses are exposed externally without permission checks, an attacker can invoke the update configuration function to inject and execute arbitrary commands. The flaw is tracked as CWE-94 and carries a CVSS 3.1 score of 9.8.
An unauthenticated remote attacker who discovers a reachable NameServer instance can leverage the configuration update path to run operating-system commands under the privileges of the RocketMQ process account, resulting in full host compromise.
Apache RocketMQ project advisories and the coordinated disclosure on the oss-security list recommend upgrading NameServer to version 5.1.2 or later for the 5.x series and to 4.9.7 or later for the 4.x series. The EPSS score remains near its recorded peak of 0.94 with no material post-disclosure climb from a low baseline.

Vulnerability details
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…
more
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.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
