The RocketMQ NameServer component has a critical remote command execution vulnerability as the CVE-2023-33246 issue was not completely fixed in version 5.1.1. This vulnerability allows attackers to exploit the update configuration function on the NameServer component when NameServer addresses are leaked on the extranet and lack permission verification. As a result, attackers can execute commands as the system users that RocketMQ is running as.
Risk to organizations includes unauthorized access and control over affected systems, leading to potential data compromise and service disruption. Given the severity of this vulnerability, organizations should prioritize patching immediately.
Users are strongly recommended to upgrade their NameServer version to 5.1.2 or above for RocketMQ 5.x or to 4.9.7 or above for RocketMQ 4.x to prevent these attacks. The CVSS score of 9.8 indicates a critical severity level, underscoring the urgency for defenders to address this vulnerability.
Currently, there are confirmed exploits available for CVE-2023-37582, which heightens the risk for organizations not yet patched against this vulnerability.
Organizations using affected versions are strongly urged to take immediate action to mitigate risks.
Vulnerability Details
CVE-2023-37582 is characterized as a remote command execution vulnerability in the RocketMQ NameServer component. The issue arises due to incomplete mitigation of the prior CVE-2023-33246. The vulnerability was published on July 12, 2023, by the Apache security team. The CVSS score of 9.8 indicates a critical severity level, with high impacts on confidentiality, integrity, and availability.
Affected versions include all versions prior to 5.1.2 for RocketMQ 5.x and all versions prior to 4.9.7 for RocketMQ 4.x.
Technical Analysis
The root cause of this vulnerability is due to insufficient permission verification when NameServer addresses are exposed. Attackers may leverage this vulnerability via a network attack vector with low complexity, requiring no privileges or user interaction.
The impacts are significant, as the vulnerability affects confidentiality, integrity, and availability. Successful exploitation can lead to unauthorized command execution on the system.
Risk & Impact Analysis
Organizations face a substantial risk of unauthorized access and control over critical systems due to this vulnerability. The potential blast radius of exploitation is high, as it can affect all users and systems using the vulnerable RocketMQ versions. Given the critical severity of this vulnerability, organizations should assess their exposure and prioritize remediation.
With a CVSS score of 9.8, this vulnerability should be treated as critical, and organizations must address it in their immediate patch cycle.
