"The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3212
advisory.

  - Twisted is an event-based framework for internet applications. Started with version 0.9.4, when the host
    header does not match a configured host `twisted.web.vhost.NameVirtualHost` will return a `NoResource`
    resource which renders the Host header unescaped into the 404 response allowing HTML and script injection.
    In practice this should be very difficult to exploit as being able to modify the Host header of a normal
    HTTP request implies that one is already in a privileged position. This issue was fixed in version
    22.10.0rc1. There are no known workarounds. (CVE-2022-39348)

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