REDHAT-BUG-2557956: Medium severity Oracle Java SE vulnerability
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).

Frequently Asked Questions
Who is exposed to this vulnerability?
Oracle Java SE deployments at versions 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1, or 27 are affected, as are Oracle GraalVM for JDK versions 17.0.20.1 and 21.0.12.1. Java clients that run sandboxed Java Web Start applications or sandboxed applets loading untrusted internet-supplied code are also affected.
What does an attacker need to exploit it?
An unauthenticated attacker needs network access through multiple protocols and must overcome high attack complexity. Exploitation can occur through APIs in the Networking component, including when a web service supplies attacker-controlled data to those APIs.
What is the impact of successful exploitation?
Successful exploitation can expose critical data or provide access to all data accessible to the affected Java SE or GraalVM for JDK deployment. The stated CVSS impact is confidentiality only; integrity and availability impacts are not listed.
