CVE-2024-20919 is a medium-severity vulnerability affecting the Oracle GraalVM for JDK and Oracle Java SE products. This vulnerability is classified with a CVSS score of 5.9, indicating potential risks that organizations must address. It allows unauthenticated attackers with network access to exploit vulnerabilities in Oracle GraalVM and Java SE, leading to unauthorized creation, deletion, or modification of critical data.
The vulnerability primarily impacts several supported versions of the Oracle Java SE and GraalVM products, including Oracle Java SE: 8u391, 11.0.21, 17.0.9, and 21.0.1, as well as Oracle GraalVM for JDK: 17.0.9 and 21.0.1. Organizations using these versions should consider the implications of this vulnerability on their systems and the data they handle.
Given the nature of this vulnerability, successful exploitation could lead to significant impacts on data integrity. As a result, organizations should prioritize remediation efforts to mitigate the risks associated with this vulnerability. The exploitation difficulty is considered high, which may deter immediate threats, but the potential consequences are severe enough to warrant immediate attention.
Organizations should prioritize patching immediately to protect their systems from potential exploitation. As the details surrounding this CVE become more widely known, the likelihood of exploitation may increase, making timely remediation critical.
Vulnerability Details
This vulnerability allows unauthenticated attackers with network access to compromise Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition. The affected components include Hotspot, and the vulnerability can be exploited by supplying data to APIs within the specified components without using Untrusted Java Web Start applications or Untrusted Java applets.
The CVSS 3.1 Base Score of 5.9 indicates that the integrity impact is high, while confidentiality and availability impacts are noted as none. The CVSS Vector is structured as follows: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N.
Technical Analysis
The root cause of CVE-2024-20919 stems from the Hotspot component of Oracle Java SE and GraalVM. The attack vector is categorized as network-based, with a high attack complexity requirement, meaning an attacker would need to have specific knowledge of the system architecture or APIs. Importantly, no privileges are required for exploitation, and user interaction is not necessary, which further heightens the risk.
The implications of this vulnerability extend to the integrity of the data handled by Oracle products, with potential unauthorized alterations to critical data. Confidentiality and availability impacts are minimal, but organizations must be vigilant regarding the integrity risks present.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized data manipulation, which can have far-reaching consequences for operational integrity and security posture. As the vulnerability affects widely used products, the potential blast radius could encompass numerous systems relying on Oracle technologies.
Organizations should assess their exposure to this vulnerability and prioritize remediation based on their risk profiles. Given the medium severity, a proactive approach towards patch management and vulnerability scanning is advised to mitigate the risks associated with this vulnerability.
