The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3346 advisory.

  - Werkzeug is a comprehensive WSGI web application library. Browsers may allow nameless cookies that look     like `=value` instead of `key=value`. A vulnerable browser may allow a compromised application on an     adjacent subdomain to exploit this to set a cookie like `=__Host-test=bad` for another subdomain. Werkzeug     prior to 2.2.3 will parse the cookie `=__Host-test=bad` as __Host-test=bad`. If a Werkzeug application is     running next to a vulnerable or malicious subdomain which sets such a cookie using a vulnerable browser,     the Werkzeug application will see the bad cookie value but the valid cookie key. The issue is fixed in     Werkzeug 2.2.3. (CVE-2023-23934)

  - Werkzeug is a comprehensive WSGI web application library. Prior to version 2.2.3, Werkzeug's multipart     form data parser will parse an unlimited number of parts, including file parts. Parts can be a small     amount of bytes, but each requires CPU time to parse and may use more memory as Python data. If a request     can be made to an endpoint that accesses `request.data`, `request.form`, `request.files`, or     `request.get_data(parse_form_data=False)`, it can cause unexpectedly high resource usage. This allows an     attacker to cause a denial of service by sending crafted multipart data to an endpoint that will parse it.
    The amount of CPU time required can block worker processes from handling legitimate requests. The amount     of RAM required can trigger an out of memory kill of the process. Unlimited file parts can use up memory     and file handles. If many concurrent requests are sent continuously, this can exhaust or kill all     available workers. Version 2.2.3 contains a patch for this issue. (CVE-2023-25577)

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

According to the versions of the python-werkzeug package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

The remote Redhat Enterprise Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2023:1018 advisory.

    Werkzeug ======== 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.
