"The version of java-1.8.0-openjdk installed on the remote host is prior to 1.8.0.372.b07-1.76. It is, therefore,
affected by a vulnerability as referenced in the ALAS-2023-1798 advisory.

  - Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE
    (component: JSSE). Supported versions that are affected are Oracle Java SE: 8u361, 8u361-perf, 11.0.18,
    17.0.6, 20; Oracle GraalVM Enterprise Edition: 20.3.9, 21.3.5 and 22.3.1. Difficult to exploit
    vulnerability allows unauthenticated attacker with network access via TLS 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 GraalVM
    Enterprise Edition accessible data as well as unauthorized access to critical data or complete access to
    all 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. (CVE-2023-21930)

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