CVE-2022-21360: Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component...

Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: ImageIO). Supported versions that are affected are Oracle Java SE: 7u321, 8u311, 11.0.13, 17.0.1; Oracle GraalVM Enterprise Edition: 20.3.4 and 21.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM Enterprise Edition. Note: This vulnerability 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. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.1 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).

Security readout for executives and security teams

Plain-English summary

CVE-2022-21360 is a Java ImageIO vulnerability that can let an unauthenticated network attacker cause a partial denial of service. The business impact is service disruption, not data theft or privilege gain, based on the provided CVSS and vendor descriptions.

Executive priority

Treat as a moderate availability risk. Patch during normal security maintenance, but accelerate for internet-facing services that process images or legacy Java clients relying on sandbox isolation.

Technical view

The flaw affects Oracle Java SE 7u321, 8u311, 11.0.13, 17.0.1 and Oracle GraalVM Enterprise Edition 20.3.4, 21.3.0. It is classified as CWE-400 and CVSS 5.3: network exploitable, low complexity, no privileges or user interaction, availability impact only.

Likely exposure

Exposure is most likely where affected Java runtimes process untrusted image data through ImageIO APIs, or legacy sandboxed Java Web Start/applets run untrusted code. General Java use is not automatically exposed without that data path or runtime version.

Exploitation context

The source states unauthenticated network access via multiple protocols may trigger partial denial of service. The bundle does not show CISA KEV listing or cited evidence of active exploitation, so active exploitation should not be assumed.

Researcher notes

Evidence supports resource-consumption style partial DoS in ImageIO. The source bundle does not provide root-cause detail, proof-of-concept status, exploit indicators, or exact fixed upstream build numbers beyond vendor update references.

Mitigation direction

  • Apply Oracle January 2022 CPU guidance for affected Java SE and GraalVM versions.
  • Upgrade OpenJDK packages using applicable Debian or Gentoo security advisories.
  • Check NetApp guidance if Java is embedded in NetApp-supported products.
  • Prioritize services accepting untrusted image data or running sandboxed untrusted Java code.
  • Retire affected legacy Java Web Start or applet deployments where possible.

Validation and detection

  • Inventory Java SE, JDK, JRE, OpenJDK, and GraalVM versions across servers and containers.
  • Identify applications using Java ImageIO on user-supplied or internet-sourced data.
  • Confirm patched package versions from Oracle, Debian, Gentoo, or product vendors.
  • Review externally reachable services that pass uploaded image data to Java APIs.
  • Document systems that cannot patch and track vendor-supported compensating guidance.
