CVE-2024-21085 represents a vulnerability in the Oracle Java SE and Oracle GraalVM Enterprise Edition products, specifically within the Concurrency component. This vulnerability is classified as low severity, with a CVSS 3.1 base score of 3.7, indicating its limited impact potential. The vulnerability allows unauthenticated attackers with network access to exploit it through various protocols, leading to a partial denial of service (DoS) in the affected software.
The specific affected versions include Oracle Java SE versions 8u401, 8u401-perf, and 11.0.22, as well as Oracle GraalVM Enterprise Edition versions 20.3.13 and 21.3.9. It is important to note that successful exploitation of this vulnerability may be achieved through APIs within the specified component, particularly in contexts where untrusted code is executed, such as Java Web Start applications or applets that load external code.
Organizations utilizing these Java platforms should prioritize patching to mitigate risks associated with this vulnerability. Given the nature of the vulnerability, an attacker could exploit it remotely, which raises concerns about potential disruptions in service availability, especially in production environments.
Organizations should address this vulnerability in their patch management processes, as even low-severity vulnerabilities can lead to unforeseen impacts if left unmitigated. Immediate remediation is advised.
Vulnerability Details
The vulnerability in question allows an unauthenticated attacker to exploit Oracle Java SE and GraalVM, leading to a partial denial of service. The CVSS score of 3.7 indicates low severity, with the potential for availability impacts but no confidentiality or integrity concerns. The affected components include Oracle Java SE versions 8u401, 8u401-perf, 11.0.22, and GraalVM Enterprise Edition versions 20.3.13 and 21.3.9.
The vulnerability was published on April 16, 2024, and has been categorized as analyzed, with no public exploit confirmed at this time. The absence of a known exploit indicates that while the vulnerability is present, active threats exploiting it have not yet been identified.
Technical Analysis
The root cause of CVE-2024-21085 is tied to the Concurrency component within the affected Java platforms. It poses a low attack complexity, where an attacker does not require any privileges or user interaction, making it easier to exploit. The attack vector is network-based, allowing attackers to potentially target systems without physical access or user involvement.
The impacts of this vulnerability manifest in terms of availability, with a potential partial denial of service resulting from successful exploitation. As such, organizations should consider monitoring their Java applications for unusual behavior that may indicate attempts to exploit this vulnerability.
Risk & Impact Analysis
Risk to organizations includes the potential for service disruptions, which can affect business operations, especially in environments relying heavily on Java applications. Given the relatively low CVSS score, organizations may initially perceive this vulnerability as low priority; however, the possibility of remote exploitation necessitates a reevaluation of its risk profile.
Organizations should assess their Java deployment strategies and ensure that all affected versions are promptly patched to avoid any exploitation attempts. The urgency for remediation is moderate, and organizations should schedule this as part of their priority patch cycle.
