The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2023:1281 advisory.

Werkzeug started as simple collection of various     utilities for WSGI applications and has become one of the most advanced     WSGI utility modules. It includes a powerful debugger, full featured     request and response objects, HTTP utilities to handle entity tags, cache     control headers, HTTP dates, cookie handling, file uploads, a powerful URL     routing system and a bunch of community contributed addon modules. Werkzeug     is unicode aware and doesn't enforce a specific template engine, database     adapter or anything else. It doesn't even enforce a specific way of     handling requests and leaves all that up to the developer. It's most useful     for end user applications which should work on as many server environments     as possible (such as blogs, wikis, bulletin boards, etc.).

Security Fix(es):

* high resource usage when parsing multipart form data with many fields     (CVE-2023-25577)

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.
