Описание

Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK product of Oracle Java SE (component: Networking). Supported versions that are affected are Oracle Java SE: 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1, 27; Oracle GraalVM for JDK: 17.0.20.1 and 21.0.12.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Java SE, Oracle GraalVM for JDK accessible data. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 5.9 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N).

A flaw was found in the OpenJDK Networking component. This vulnerability allows an unauthenticated remote attacker with network access to cause an information disclosure. By supplying crafted input to networking Application Programming Interfaces (APIs), such as through an exposed web service, an attacker could exploit this flaw to gain unauthorized access to critical data.

Отчет

This vulnerability is rated as having a Moderate severity rather than Important due to the high attack complexity required for successful exploitation. While unauthenticated remote callers could potentially trigger information exposure, exploitation hinges on target applications passing untrusted input directly into internal OpenJDK HTTP client caching routines. Workloads that do not process untrusted network requests through affected caching APIs are not exposed to this issue.
