"The remote Redhat Enterprise Linux 9 host has a package installed that is affected by a vulnerability as referenced in
the RHSA-2024:0214 advisory.

    Werkzeug is a WSGI utility module. It includes a debugger, request and response objects, HTTP utilities to
    handle entity tags, cache control headers, HTTP dates, cookie handling, file uploads, a URL routing system
    and a numerous community contributed add-on modules.

    Werkzeug is unicode aware and does not enforce a specific template engine, database adapter or a specific
    way of handling requests. It is useful for end user applications, such as blogs, wikis, and bulletin
    boards, that need to  operate in a wide variety of server environments.

    Security Fix(es):

    * high resource consumption leading to denial of service (CVE-2023-46136)

    For more details about the security issue(s), including the impact, a CVSS
    score, acknowledgments, and other related information, refer to the CVE
    page listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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