Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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: 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).

dbcve analysis · high confidence

CVE-2022-21277 is a denial-of-service vulnerability in the ImageIO component of Oracle Java SE (versions 11.0.13 and 17.0.1) and Oracle GraalVM Enterprise Edition (versions 20.3.4 and 21.3.0). The vulnerability allows an unauthenticated remote attacker to cause partial DOS via network access through multiple protocols, specifically affecting Java deployments that run sandboxed code or expose ImageIO APIs.

MitigationApply the applicable Oracle security patch for Java SE or GraalVM Enterprise Edition to address this vulnerability. For client-side deployments, ensure Java Web Start applications and applets run within properly configured sandboxes.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Java version
    Run 'java -version' or check the JRE/JDK installation directory for version information
    Affected if The version matches Oracle OpenJDK >= 11 but <= 11.0.13; >= 13 but <= 13.0.9; >= 15 but <= 15.0.5; = 17; or = 17.0.1, OR matches Oracle JDK/JRE = 11.0.13 or = 17.0.1, OR matches Oracle GraalVM = 20.3.4 or = 21.3.0
  2. Identify installed NetApp product versions
    Check the installed version of NetApp 7 Mode Transition Tool, NetApp Active Iq Unified Manager, or NetApp Cloud Insights Acquisition Unit
    Affected if Any version of these NetApp products is installed (they are all affected regardless of version)
  3. Determine if ImageIO is in use
    Search application code for imports of javax.imageio or java.imageio, and review if ImageIO.read() or other ImageIO APIs are called
    Affected if The application uses ImageIO.read() or other ImageIO methods to process image data
  4. Check if application runs sandboxed code or exposes ImageIO APIs over network
    Review application configuration for SecurityManager settings, Java Web Start usage, or any network-exposed endpoints that use ImageIO
    Affected if The Java deployment runs sandboxed code (SecurityManager enabled) or exposes ImageIO APIs through network-accessible services

You are affected if you run any of the listed Oracle Java SE, OpenJDK, JDK, JRE, or GraalVM versions within the specified ranges, or any version of the listed NetApp products, and your deployment uses ImageIO APIs or runs sandboxed code accessible over the network.

Upgrade available Upgrade to a release after 15.0.5
Interim mitigation

Apply the applicable Oracle security patch for Java SE or GraalVM Enterprise Edition to address this vulnerability. For client-side deployments, ensure Java Web Start applications and applets run within properly configured sandboxes.

Recommended fix High confidence

Oracle Java SE 11.0.14+ or 17.0.2+; OpenJDK 11.0.14+/13.0.10+/15.0.6+/17.0.2+; GraalVM Enterprise Edition 20.3.5+ or 21.3.1+

  1. 1. Identify the exact Java/OpenJDK/JRE version currently installed by running 'java -version' or checking the package manager
  2. 2. For Oracle Java SE installations: Upgrade to Oracle Java SE 11.0.14 or later, or 17.0.2 or later
  3. 3. For OpenJDK installations: Upgrade to a version beyond the affected range (e.g., OpenJDK 11.0.14+, 13.0.10+, 15.0.6+, or 17.0.2+)
  4. 4. For GraalVM Enterprise Edition: Upgrade to version 20.3.5+ or 21.3.1+
  5. 5. For Debian systems: Run 'apt-get update && apt-get upgrade' to receive security updates for openjdk packages
  6. 6. Verify the upgrade was successful by running 'java -version' and confirming the new version is installed
  7. 7. Test any applications that rely on ImageIO functionality to ensure proper operation after the upgrade
Caveat Minor release upgrades typically have backward compatibility, but test applications in a staging environment before production deployment as ImageIO behavior may slightly change
