CVE-2024-21217 is a vulnerability found in Oracle Java SE and its associated components, including Oracle GraalVM for JDK and Oracle GraalVM Enterprise Edition. This vulnerability, classified as low severity with a CVSS score of 3.7, can potentially be exploited by an unauthenticated attacker with network access. The exploitation could lead to a partial denial of service (partial DoS) affecting the availability of these products.
The risk to organizations includes disruption to services relying on Oracle Java SE and GraalVM components. Although the vulnerability is difficult to exploit, its existence in widely used products necessitates attention. Organizations should prioritize this in their patching cycles.
As of now, there are no known exploits or proofs of concept available for this vulnerability. However, organizations are encouraged to remain vigilant and monitor for any updates from Oracle regarding this vulnerability.
Given the impact this vulnerability may have, organizations should schedule remediation and ensure they are utilizing the latest versions of Oracle Java SE and GraalVM products.
Vulnerability Details
This vulnerability allows potential exploitation in Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition due to issues in the serialization component. Supported affected versions include Oracle Java SE: 8u421, 8u421-perf, 11.0.24, 17.0.12, 21.0.4, 23; Oracle GraalVM for JDK: 17.0.12, 21.0.4, 23; and Oracle GraalVM Enterprise Edition: 20.3.15 and 21.3.11.
The CVSS 3.1 Base Score is 3.7, indicating low severity primarily affecting availability. The attack vector is network-based, requiring no privileges or user interaction for exploitation.
Technical Analysis
The root cause of this vulnerability lies in the serialization component of the affected products. Attackers may leverage network access to exploit the vulnerability, which is characterized by high attack complexity. No privileges are required for exploitation, and user interaction is not necessary, making it easier for attackers to launch an attack.
The confidentiality and integrity impacts are rated as none, while the availability impact is low, which may result in a partial denial of service.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2024-21217 is moderate. Organizations utilizing the affected versions of Oracle Java SE and GraalVM should be aware that the vulnerability can disrupt operations, especially in environments relying on these technologies for critical applications.
Despite the low severity rating, the potential for a partial denial of service means that organizations should assess their exposure and plan for remediation. The urgency of addressing this vulnerability should be determined by the organization's risk tolerance and deployment context.
