CVE-2024-21235 is a medium-severity vulnerability affecting Oracle GraalVM for JDK and several versions of Oracle Java SE. This vulnerability allows unauthenticated attackers with network access to compromise the affected systems via multiple protocols. The vulnerability is classified under CVSS 3.1 with a score of 4.8, indicating a moderate risk level that organizations should not overlook.
Risk to organizations includes unauthorized update, insert, or delete access to data within Oracle Java SE and GraalVM products. Successful exploitation can also lead to unauthorized read access to sensitive data. As attackers may leverage this vulnerability through APIs, organizations should be particularly vigilant about controlling exposure points.
Given the potential impact of this vulnerability, organizations should prioritize patching immediately. Implementing effective security measures and keeping systems updated can significantly reduce the risk associated with this vulnerability.
The vulnerability affects supported versions of Oracle Java SE, including 8u421, 11.0.24, 17.0.12, and more. Additionally, it applies to Oracle GraalVM for JDK versions 17.0.12, 21.0.4, and 23, as well as Oracle GraalVM Enterprise Edition versions 20.3.15 and 21.3.11.
Organizations should assess their environments to identify if they are using any affected versions and take necessary remediation steps.
Vulnerability Details
The vulnerability in question affects the Hotspot component of the Oracle Java SE and Oracle GraalVM products. The vulnerability is categorized as having low confidentiality and integrity impacts. Specifically, the CVSS vector indicates that the attack vector is network-based, with a high attack complexity, requiring no privileges or user interaction.
Oracle has not provided a CWE classification for this vulnerability. The publication date of the CVE was October 15, 2024, and it is still classified as modified with ongoing assessments regarding its exploitation.
Technical Analysis
The root cause of this vulnerability stems from flaws in the implementation of the Hotspot component, which enables attackers to exploit system weaknesses. The attack vector is primarily network-based, allowing remote exploitation, which poses significant risks to organizations that rely on these technologies.
The attack complexity is considered high, meaning that while the vulnerability exists, successfully exploiting it may require specific conditions or configurations. Importantly, no privileges are required for an attacker, and user interaction is not necessary to exploit this vulnerability.
The impacts on confidentiality and integrity are both rated low, indicating that while data may be accessed or modified, the overall risk to availability is not affected.
Risk & Impact Analysis
Real-world deployment risk for this vulnerability is notable, particularly for organizations that utilize Oracle Java SE and GraalVM in public-facing applications. The ease of exploitation through network access coupled with low prerequisites for an attacker increases the potential blast radius.
Organizations should assess their current exposure and address this vulnerability in their priority patch cycle. Given the medium severity level, organizations should pivot their focus toward remediation efforts to mitigate risks effectively.
