Описание

Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Lightweight HTTP Server). Supported versions that are affected are Oracle Java SE: 8u503, 8u503-perf, 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; Oracle GraalVM Enterprise Edition: 21.3.19.1.1. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability can only be exploited by supplying data to APIs in the specified Component without using Untrusted Java Web Start applications or Untrusted Java applets, such as through a web service. CVSS 3.1 Base Score 5.3 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).

A flaw was found in OpenJDK's Lightweight HTTP Server. An unauthenticated remote attacker can exploit this vulnerability over the network by sending crafted requests to exposed server Application Programming Interfaces (APIs). Successful exploitation allows an attacker to perform unauthorized data modifications, potentially inserting, altering, or deleting accessible application data.

Отчет

This vulnerability is rated as Moderate severity because exploitation requires an application to actively instantiate and expose the embedded OpenJDK lightweight HTTP server to untrusted network traffic, and successful attacks result only in partial integrity compromise without exposing data confidentiality or impacting service availability. OpenJDK packages shipped with Red Hat Enterprise Linux provide this lightweight server API primarily for embedded testing and lightweight standalone utilities rather than general-purpose production web services. Consequently, standard deployments that do not expose custom applications utilizing this specific internal HTTP server interface remain unaffected.
