CVE-2024-21012: Low Vulnerability in Oracle Java SE and GraalVM

CVE-2024-21012 is a vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition products, specifically related to the Networking component. This vulnerability allows an unauthenticated attacker with network access via multiple protocols to compromise the affected systems. The vulnerability affects supported versions of Oracle Java SE: 11.0.22, 17.0.10, 21.0.2, and 22; Oracle GraalVM for JDK: 17.0.10, 21.0.2, and 22; as well as Oracle GraalVM Enterprise Edition: 20.3.13 and 21.3.9.

The CVSS 3.1 Base Score is 3.7, indicating a low severity level. Risk to organizations includes potential unauthorized update, insert, or delete access to accessible data within these Java environments. This vulnerability is particularly relevant for Java deployments running sandboxed applications that load untrusted code, which rely on the Java sandbox for security.

Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. Although the exploitability is considered low, the potential for unauthorized access necessitates a proactive approach to remediation.

This vulnerability does not affect Java deployments that run only trusted code, such as those typically found in server environments. Understanding the context of this vulnerability is essential for organizations utilizing Oracle Java SE and GraalVM products.

Vulnerability Details

The vulnerability allows an unauthorized attacker to access sensitive data, which emphasizes the importance of ensuring that all Java deployments are configured correctly. The vulnerability is classified under CWE-276, which addresses improper handling of sensitive information. The official CVE description highlights its impact, particularly in environments where untrusted code is executed.

Technical Analysis

The root cause of CVE-2024-21012 lies in the networking component of the affected products. An attacker can exploit this vulnerability through a network vector, with high complexity and no privileges required. User interaction is not necessary for exploitation, and its impact is limited to integrity, with no confidentiality or availability impacts.

Risk & Impact Analysis

Risk to organizations includes potential unauthorized access to sensitive data, particularly in client-side applications running Java Web Start or similar technologies. With a low CVSS score of 3.7 and an EPSS score placing it in the 34th percentile, the urgency for addressing this vulnerability is categorized as moderate. Organizations should schedule remediation within their patch cycle.
