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 Java SE component of Oracle Java SE (subcomponent: Windows DLL). The supported version that is affected is Java SE: 8u202. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. While the vulnerability is in Java SE, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), 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 3.0 Base Score 9.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H).

Recommended fix High confidence

Java SE 8u211 or later (latest available JDK 8 from Oracle)

  1. 1. Identify the current Java version by running 'java -version' in command prompt or terminal
  2. 2. Navigate to the Oracle Java SE Downloads page: https://www.oracle.com/java/technologies/downloads/
  3. 3. Download Java SE 8 (JDK 8) update 211 or later, or the latest available JDK 8 release from Oracle
  4. 4. Run the installer and follow the installation prompts to install the updated JDK
  5. 5. Update the JAVA_HOME environment variable to point to the new JDK installation directory (e.g., C:\Program Files\Java\jdk1.8.0_xxx)
  6. 6. Update the PATH variable to ensure the new Java bin directory is prioritized
  7. 7. Verify the upgrade by running 'java -version' and confirming it shows version 8u211 or later
Caveat Minor - Upgrades within JDK 8 maintain backward compatibility; however, test critical applications to ensure compatibility with the new update
