"The version of resteasy-base installed on the remote host is prior to 3.0.6-4. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2-2024-2398 advisory.

  - A flaw was found in RESTEasy in all versions of RESTEasy up to 4.6.0.Final. The endpoint class and method
    names are returned as part of the exception response when RESTEasy cannot convert one of the request URI
    path or query values to the matching JAX-RS resource method's parameter value. The highest threat from
    this vulnerability is to data confidentiality. (CVE-2021-20289)

  - In RESTEasy the insecure File.createTempFile() is used in the DataSourceProvider, FileProvider and
    Mime4JWorkaround classes which creates temp files with insecure permissions that could be read by a local
    user. (CVE-2023-0482)

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