CVE-2024-21094 is a vulnerability found in the Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition products. The severity of this vulnerability is classified as low, with a CVSS score of 3.7. Although this vulnerability is considered difficult to exploit, it allows unauthenticated attackers with network access to potentially compromise these systems via multiple protocols. Successful exploitation can lead to unauthorized updates, insertions, or deletions of accessible data.

Organizations that deploy affected versions of Oracle Java SE (including versions 8u401, 11.0.22, 17.0.10, 21.0.2, and 22) and Oracle GraalVM (including versions 17.0.10, 21.0.2, and 22) should take immediate action. The vulnerability's exploitation can occur through APIs in the specified component, particularly in Java deployments running sandboxed applications that load untrusted code. This highlights the importance of maintaining strict security measures.

Given its low CVSS score, organizations might perceive this issue as less urgent; however, they should not underestimate the potential impact. Risk to organizations includes unauthorized access to sensitive data, which can lead to compliance issues and reputational damage. Organizations should prioritize patching this vulnerability as part of their routine maintenance.

The vulnerability was published on April 16, 2024, and organizations should verify their versions against the affected ones to ensure they are not at risk. Active monitoring and patching of Java SE and GraalVM installations is crucial to maintaining a secure environment.

Vulnerability Details

The vulnerability affects Oracle Java SE (component: Hotspot) and has been assigned a CVSS 3.1 Base Score of 3.7, indicating low severity. The vulnerability can impact integrity, allowing unauthorized changes to data. The supported versions affected include Oracle Java SE: 8u401, 11.0.22, 17.0.10, 21.0.2, and 22; Oracle GraalVM for JDK: 17.0.10, 21.0.2, and 22; and Oracle GraalVM Enterprise Edition: 20.3.13 and 21.3.9. The CVSS vector is (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N).

Technical Analysis

The root cause of this vulnerability lies in the handling of API calls within the Java environment. Attackers may exploit this vulnerability through network access, targeting systems that utilize untrusted code. The attack complexity is classified as high, meaning that while exploitation is difficult, it is still possible under certain conditions. No privileges are required to exploit this vulnerability, and no user interaction is needed.

In terms of impact, the confidentiality impact is none, while integrity impact is low, indicating that unauthorized changes can be made. There is no availability impact associated with this vulnerability, further emphasizing the need for organizations to maintain their Java environments securely.

Risk & Impact Analysis

The risk to organizations includes unauthorized changes to application data, which can have downstream effects on data integrity and overall application functionality. This vulnerability, while rated low, could serve as an entry point for more serious attacks if not mitigated. Given its CVSS score, organizations should address this issue in their priority patch cycle, ensuring that all affected systems are updated promptly.

Affected Versions

The affected versions for this vulnerability include Oracle Java SE: 8u401, 11.0.22, 17.0.10, 21.0.2, and 22; Oracle GraalVM for JDK: 17.0.10, 21.0.2, and 22; and Oracle GraalVM Enterprise Edition: 20.3.13 and 21.3.9. Organizations should ensure they are running versions that are patched against this vulnerability.

Mitigation & Remediation

Organizations should prioritize patching immediately. Upgrading to the latest version of Oracle Java SE or GraalVM that addresses this vulnerability is essential. In instances where immediate patching is not feasible, organizations should consider implementing configuration hardening to restrict API access and monitor network traffic for unauthorized attempts to exploit this vulnerability. Additionally, continuous security testing can help in identifying and addressing similar vulnerabilities in the future.

Detection Guidance

Monitoring logs for unusual API access patterns is critical. Organizations should look for behavioral anomalies associated with unauthorized data modifications. Network signatures related to known exploit attempts should also be tracked to ensure prompt detection of potential exploitation attempts. System changes, particularly in Java applications, should be monitored closely to identify unauthorized alterations.

AppSecure Threat Intelligence Insight
