CVE-2024-21131 is a low-severity vulnerability affecting several Oracle products, particularly Oracle GraalVM and Oracle Java SE. The vulnerability has a CVSS score of 3.7, indicating a low level of risk. However, organizations should not overlook this vulnerability, as it can allow unauthenticated attackers with network access to compromise Oracle Java SE and Oracle GraalVM. Successful exploitation can result in unauthorized access to data, including update, insert, or delete operations.
The vulnerability is particularly relevant for environments utilizing APIs in the specified components, such as web services. It can also impact Java deployments, especially in clients running sandboxed Java Web Start applications or Java applets that load untrusted code. Given the potential impact on data integrity, organizations should assess their exposure and implement necessary controls.
The urgency for defenders is moderate, and organizations should schedule remediation as part of their patch management process. While the exploitation complexity is high, the existence of this vulnerability necessitates attention to prevent possible unauthorized access.
This vulnerability is not currently listed in the Known Exploited Vulnerabilities (KEV) catalog, and no public exploit or proof of concept has been confirmed. However, the potential for exploitation remains a concern for affected organizations.
Organizations should prioritize monitoring their systems for any signs of exploitation and ensure their security practices are robust enough to handle potential threats stemming from this vulnerability.
Vulnerability Details
CVE-2024-21131 affects the Oracle Java SE and Oracle GraalVM for JDK products, specifically in the Hotspot component. Supported affected versions include Oracle Java SE: 8u411, 8u411-perf, 11.0.23, 17.0.11, 21.0.3, 22.0.1; Oracle GraalVM for JDK: 17.0.11, 21.0.3, 22.0.1; and Oracle GraalVM Enterprise Edition: 20.3.14 and 21.3.10.
The CVSS 3.1 Base Score is 3.7 with the following vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N, indicating integrity impacts with no confidentiality or availability impacts.
Technical Analysis
The root cause of CVE-2024-21131 is linked to the Hotspot component of Oracle Java SE and GraalVM. The attack vector is network-based, necessitating an unauthenticated attacker with low privileges to exploit the vulnerability. The attack complexity is high, requiring specific conditions to be met for a successful attack.
User interaction is not required, and attackers may exploit the vulnerability through APIs. Confidentiality is not impacted, but the integrity of accessible data can be compromised, resulting in unauthorized updates, inserts, or deletions. Availability impact is not applicable.
Risk & Impact Analysis
The risk to organizations includes potential unauthorized access to sensitive data and the ability for attackers to manipulate or delete data within the affected Oracle products. The blast radius is significant due to the wide usage of Java SE and GraalVM in various applications.
Organizations should assess their exposure to this vulnerability, particularly if they utilize affected Oracle products in their environments. Given the moderate urgency indicated by the CVSS score, organizations should schedule remediation within their patch management cycles.
