"The version of java-11-amazon-corretto installed on the remote host is prior to 11.0.16+8-1. It is, therefore, affected
by multiple vulnerabilities as referenced in the ALAS2-2022-1823 advisory.

  - Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE
    (component: Hotspot). Supported versions that are affected are Oracle Java SE: 7u343, 8u333, 11.0.15.1,
    17.0.3.1, 18.0.1.1; Oracle GraalVM Enterprise Edition: 20.3.6, 21.3.2 and 22.1.0. 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 read access to a subset of Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data.
    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 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).

    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 creation, deletion or modification access to critical data or all Oracle Java SE, Oracle

    (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N). (CVE-2022-21541)

  - The Apache Xalan Java XSLT library is vulnerable to an integer truncation issue when processing malicious
    XSLT stylesheets. This can be used to corrupt Java class files generated by the internal XSLTC compiler
    and execute arbitrary Java bytecode. The Apache Xalan Java project is dormant and in the process of being
    retired. No future releases of Apache Xalan Java to address this issue are expected. Note: Java runtimes
    (such as OpenJDK) include repackaged copies of Xalan. (CVE-2022-34169)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
