CVE-2024-20926 is classified as a medium-severity vulnerability with a CVSS score of 5.9, identified in several Oracle products including GraalVM and Java SE. This vulnerability allows unauthenticated attackers with network access to exploit it through multiple protocols, leading to unauthorized access to critical data. The potential impacts are significant, as successful exploitation could grant attackers complete access to data managed by Oracle Java SE and GraalVM.
Given the nature of this vulnerability, organizations utilizing affected versions should prioritize remediation. The risk to organizations includes potential data breaches and unauthorized manipulation of sensitive information. It is essential for security teams to assess their environments promptly and apply necessary mitigations.
The vulnerability is categorized as difficult to exploit but still poses a risk, particularly in environments where untrusted code may be executed. Organizations are urged to monitor their systems for any signs of exploitation and act swiftly to mitigate the risks.
Organizations should prioritize patching immediately to safeguard their systems and data integrity.
Vulnerability Details
The vulnerability exists in Oracle Java SE and Oracle GraalVM products (component: Scripting), affecting versions including Oracle Java SE 8u391, 11.0.21; and GraalVM versions 17.0.9, 20.3.12, 21.3.8, and 22.3.4. The CVSS vector is (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating a high confidentiality impact with no integrity or availability impact.
The vulnerability is classified under several CWEs, including CWE-284 (Improper Access Control), CWE-502 (Deserialization of Untrusted Data), and CWE-693 (Protection Mechanism Failure).
Technical Analysis
The root cause of this vulnerability stems from inadequate access controls within the affected components. Attackers may exploit this flaw through network access using various protocols. The attack complexity is rated as high, meaning that specific conditions must exist for the exploit to be successful. Notably, the attacker requires no privileges and no user interaction is necessary to trigger the vulnerability.
The potential impact includes significant confidentiality breaches, allowing attackers to access sensitive data without proper authorization. However, the integrity and availability of the systems remain unaffected, making the primary concern data leakage.
Risk & Impact Analysis
Organizations deploying affected versions of Oracle GraalVM and Java SE may face serious risks, especially if untrusted code is executed in their environments. The blast radius of this vulnerability can extend to critical data and services, potentially leading to widespread data breaches.
The urgency for remediation is medium, and organizations should address this vulnerability in their patch cycle. Regular monitoring and assessment of security practices are essential for maintaining data integrity and preventing unauthorized access.
