CVE-2024-21210 is a low-severity vulnerability affecting Oracle Java SE, specifically in the Hotspot component. The vulnerability has a CVSS score of 3.7, indicating a low risk of exploitation. This vulnerability allows an unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Organizations using supported versions such as Oracle Java SE: 8u421, 11.0.24, and 17.0.12 should be aware of this risk.
Successful exploitation can result in unauthorized update, insert, or delete access to some of Oracle Java SE's accessible data. The vulnerability can be exploited through APIs in the specified component, particularly in environments where untrusted code is executed, such as sandboxed Java Web Start applications or applets.
Organizations should prioritize addressing this vulnerability, especially those that rely on Java applications that process external data. While the complexity of exploitation is high, the potential for unauthorized access necessitates appropriate action.
Given the nature of this vulnerability, organizations are advised to monitor for any potential impacts and to ensure that their Java environments are updated to secure versions.
Vulnerability Details
The vulnerability described in CVE-2024-21210 is categorized under CWE-203, which pertains to exposure of sensitive information. The affected versions of Oracle Java SE include: 8u421, 11.0.24, 17.0.12, 21.0.4, and 23.
The CVSS 3.1 vector for this vulnerability is AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N, indicating that it has a network attack vector and a high attack complexity. The integrity impact is low, meaning that unauthorized modifications to data could occur, but the confidentiality and availability impacts are noted as none.
Technical Analysis
The root cause of this vulnerability stems from insufficient validation when processing external data through APIs. This leads to the possibility of unauthorized access to Oracle Java SE data by unauthenticated users through network-based attacks.
The attack vector is network-based, requiring high complexity to exploit. No privileges are required from the attacker, and user interaction is not needed. The vulnerability primarily affects the integrity of the data, allowing unauthorized modifications without impacting confidentiality or availability.
Risk & Impact Analysis
Risk to organizations includes unauthorized access and modification of data within Java applications, which could lead to broader security concerns if exploited. The potential blast radius, while limited by the complexity of exploitation, remains a concern for organizations running affected versions, especially those utilizing Java for critical business functions.
Organizations should schedule remediation as part of their routine maintenance cycle. Given the low CVSS score, immediate action is not strictly necessary, but updating to secure versions should be prioritized, especially for environments exposed to untrusted code.
