The version of python-twisted-web installed on the remote host is prior to 12.1.0-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2022-1827 advisory.

  - Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to version     22.4.0rc1, the Twisted Web HTTP 1.1 server, located in the `twisted.web.http` module, parsed several HTTP     request constructs more leniently than permitted by RFC 7230. This non-conformant parsing can lead to     desync if requests pass through multiple HTTP parsers, potentially resulting in HTTP request smuggling.
    Users who may be affected use Twisted Web's HTTP 1.1 server and/or proxy and also pass requests through a     different HTTP server and/or proxy. The Twisted Web client is not affected. The HTTP 2.0 server uses a     different parser, so it is not affected. The issue has been addressed in Twisted 22.4.0rc1. Two     workarounds are available: Ensure any vulnerabilities in upstream proxies have been addressed, such as by     upgrading them; or filter malformed requests by other means, such as configuration of an upstream proxy.
    (CVE-2022-24801)

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