"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied
patch available.

  - OpenSearch is an open source distributed and RESTful search engine. In affected versions there is an issue
    in the implementation of field-level security (FLS) and field masking where rules written to explicitly
    exclude fields are not correctly applied for certain queries that rely on their auto-generated .keyword
    fields. This issue is only present for authenticated users with read access to the indexes containing the
    restricted fields. This may expose data which may otherwise not be accessible to the user. OpenSearch
    1.0.0-1.3.7 and 2.0.0-2.4.1 are affected. Users are advised to upgrade to OpenSearch 1.3.8 or 2.5.0. Users
    unable to upgrade may write explicit exclusion rules as a workaround. Policies authored in this way are
    not subject to this issue. (CVE-2023-23613)

Note that Nessus relies on the presence of the package as reported by the vendor.");
