CVE-2024-21011 is a vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition products. This vulnerability allows unauthenticated attackers with network access via multiple protocols to compromise these products. Specifically, successful exploitation can lead to unauthorized partial denial of service (partial DoS) of the affected components, posing a risk to organizations relying on these technologies.
The vulnerability has a CVSS 3.1 base score of 3.7, categorized as low severity. This indicates that while the exploitability is considered low, the potential availability impact requires attention from security teams. Organizations should prioritize patching to prevent unauthorized access resulting from this vulnerability.
Organizations using the affected versions are encouraged to implement the necessary remediations. The vulnerability is of particular concern for deployments utilizing sandboxed Java Web Start applications or applets that load untrusted code from the internet.
The publication date of this vulnerability was April 16, 2024, and it is critical for organizations to assess their exposure and implement mitigations as soon as possible.
Vulnerability Details
CVE-2024-21011 is classified as a vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition, specifically within the Hotspot component. The affected versions include Oracle Java SE versions 8u401, 8u401-perf, 11.0.22, 17.0.10, 21.0.2, and 22; Oracle GraalVM for JDK versions 17.0.10, 21.0.2, and 22; and Oracle GraalVM Enterprise Edition versions 20.3.13 and 21.3.9.
The CVSS score of 3.7 indicates a low severity level, reflecting a low potential for exploitation. Organizations must recognize that even low-severity vulnerabilities can have significant implications depending on their environment and usage context.
The vulnerability impacts the availability of the affected systems, as indicated by the CVSS vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L).
Technical Analysis
The root cause of CVE-2024-21011 is attributed to a complex interaction within the Oracle Java SE and GraalVM components, which can be exploited by unauthenticated attackers with network access. The attack vector is classified as network-based, with a high attack complexity due to the nature of exploitation requirements.
No privileges are required for exploitation, and user interaction is not necessary. The potential impact on confidentiality and integrity is noted as none, while availability impact is categorized as low, indicating that the system can be partially disrupted.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access and partial denial of service, which could disrupt normal operations. Given that this vulnerability affects widely used components in applications reliant on Java technologies, the blast radius could be significant, especially in environments with large deployments.
Organizations should assess their exposure based on the CVSS score of 3.7 and consider this vulnerability as part of their risk management strategies. Although it is classified as low severity, the potential for exploitation in critical systems cannot be overlooked.
Organizations should address this vulnerability in their priority patch cycle to ensure that their applications remain secure.
