CVE-2023-51653 is a critical vulnerability affecting Apache Hertzbeat, a real-time monitoring system. This vulnerability allows JNDI injection through the `JMXConnectorFactory.connect` method in the `JmxCollectImpl.java` implementation. When a specific URL is provided, such as `service:jmx:rmi:///jndi/rmi://xxxxxxx:1099/localHikari`, it can be exploited to execute arbitrary code remotely. With a CVSS score of 9.8, this vulnerability poses significant risks to organizations, necessitating immediate attention.
The vulnerability was published on February 22, 2024, and affects all versions of Hertzbeat prior to 1.4.1. Organizations utilizing affected versions should prioritize patching to the secure version to mitigate potential exploitation risks. The urgency is classified as critical due to the potential for remote code execution, which could lead to significant data breaches and system compromises.
As of now, there are no confirmed public exploits or proof of concept (PoC) available for exploiting this vulnerability. Nonetheless, given the nature of the issue, organizations should not underestimate the risk, considering the severity and potential impact it could have on their systems. Organizations should prioritize patching immediately.
In summary, CVE-2023-51653 represents a serious risk to Apache Hertzbeat users. The quick application of the patch provided in version 1.4.1 is essential for protecting against possible exploitation.
Vulnerability Details
The official description states that this vulnerability allows JNDI injection through `JMXConnectorFactory.connect`. The relevant endpoint is `/api/monitor/detect`, which uses a URL field that can be manipulated by attackers. The vulnerability has been assigned a CWE classification of CWE-74, indicating improper neutralization of special elements in output used by a downstream component.
The CVSS score of 9.8 classifies this vulnerability as critical, indicating a high potential for exploitation with a low level of complexity. Attackers require no privileges and no user interaction is needed, making this vulnerability particularly dangerous.
Technical Analysis
The root cause of this vulnerability is the improper handling of user input in the JMX connection setup. The attack vector is network-based, allowing remote attackers to exploit the vulnerability without physical access. The attack complexity is low, and no privileges are required, making it easier for attackers to execute their malicious payloads.
No user interaction is required for this vulnerability, which increases the risk substantially. The confidentiality, integrity, and availability impacts are all rated as high, indicating that successful exploitation could lead to complete system control and data exposure.
Risk & Impact Analysis
The real-world risk associated with CVE-2023-51653 is significant. Organizations using Apache Hertzbeat in production environments are at high risk of remote code execution through JNDI injection. Given the high CVSS score, organizations must assess the potential impact on their systems and the data they handle.
The blast radius of this vulnerability could extend beyond individual systems, potentially affecting network integrity and leading to further compromises. It is crucial that organizations address this vulnerability in their priority patch cycle to mitigate associated risks and protect their assets.
