Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Security). Supported versions that are affected are Oracle Java SE: 8u501, 11.0.32, 17.0.20, 21.0.12, 25.0.4, 26.0.2; Oracle GraalVM for JDK: 17.0.20 and 21.0.12; Oracle GraalVM Enterprise Edition: 21.3.19. Difficult to exploit 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 read access to a subset 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 3.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N).
A flaw was found in OpenJDK. The XML cryptographic component does not properly utilize the base Uniform Resource Identifier (URI) when resolving external references during data retrieval. A remote attacker could exploit this flaw by providing crafted XML input to induce the application to fetch resources from unintended locations. This issue can result in unauthorized information disclosure.
Отчет
This vulnerability is rated as Moderate severity because successful exploitation requires specific conditions where Java applications parse untrusted cryptographic signatures with external URI resolution permitted, limiting the potential blast radius to partial confidentiality loss. In standard Red Hat Enterprise Linux environments, services running OpenJDK do not routinely dereference external resources within XML signature contexts unless explicitly configured to do so. An attacker who can supply maliciously structured XML data could cause the server to send unexpected outbound network requests, potentially accessing internal endpoints. System integrity and overall service availability remain unaffected.
