"The version of OpenJDK installed on the remote host is 7 prior to 7u291 / 8 prior to 8u282 / 11.0.0 prior to 11.0.10 /
13.0.0 prior to 13.0.6 / 15.0.0 prior to 15.0.2 / 16.0.0 prior to 16.0.0. It is, therefore, affected by multiple
vulnerabilities as referenced in the 2021-04-20 advisory.

Please Note: Java CVEs do not always include OpenJDK versions, but are confirmed separately by Tenable using the patch
versions from the referenced OpenJDK security advisory.

  - Vulnerability in the Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition product of Oracle Java
    SE (component: Libraries). Supported versions that are affected are Java SE: 7u291, 8u281, 11.0.10, 16;
    Java SE Embedded: 8u281; Oracle GraalVM Enterprise Edition: 19.3.5, 20.3.1.2 and 21.0.0.2. Difficult to
    exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to
    compromise Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition. Successful attacks of this
    vulnerability can result in unauthorized creation, deletion or modification access to critical data or all
    Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability
    applies to Java deployments that load and run untrusted code (e.g., code that comes from the internet) and
    rely on the Java sandbox for security. It can also be exploited by supplying untrusted data to APIs in the
    specified Component. (CVE-2021-2161)

    exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to
    compromise Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition. Successful attacks require human
    interaction from a person other than the attacker. Successful attacks of this vulnerability can result in
    unauthorized creation, deletion or modification access to critical data or all Java SE, Java SE Embedded,
