"The version of axis installed on the remote host is prior to 1.2.1-7.5.15. It is, therefore, affected by a vulnerability
as referenced in the ALAS-2023-1840 advisory.

  - ** UNSUPPPORTED WHEN ASSIGNED ** ** UNSUPPORTED WHEN ASSIGNED ** When integrating Apache Axis 1.x in an
    application, it may not have been obvious that looking up a service through ServiceFactory.getService
    allows potentially dangerous lookup mechanisms such as LDAP. When passing untrusted input to this API
    method, this could expose the application to DoS, SSRF and even attacks leading to RCE. As Axis 1 has been
    EOL we recommend you migrate to a different SOAP engine, such as Apache Axis 2/Java. As a workaround, you
    may review your code to verify no untrusted or unsanitized input is passed to ServiceFactory.getService,
    or by applying the patch from https://github.com/apache/axis-
    axis1-java/commit/7e66753427466590d6def0125e448d2791723210 . The Apache Axis project does not expect to
    create an Axis 1.x release fixing this problem, though contributors that would like to work towards this
    are welcome. (CVE-2023-40743)

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