It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-231 advisory.

  - twisted is an event-driven networking engine written in Python. In affected versions twisted exposes     cookies and authorization headers when following cross-origin redirects. This issue is present in the     `twited.web.RedirectAgent` and `twisted.web. BrowserLikeRedirectAgent` functions. Users are advised to     upgrade. There are no known workarounds. (CVE-2022-21712)

  - Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 22.2.0,     Twisted SSH client and server implement is able to accept an infinite amount of data for the peer's SSH     version identifier. This ends up with a buffer using all the available memory. The attach is a simple as     `nc -rv localhost 22 < /dev/zero`. A patch is available in version 22.2.0. There are currently no known     workarounds. (CVE-2022-21716)

  - 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 these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-056 advisory.

    A flaw was found in the twisted Python library when WebClient redirects via the RedirectAgent and     BrowserLikeRedirectAgent methods. This flaw allows an attacker to take advantage of these cross-origin     redirects and leak the cookie and authorization headers. (CVE-2022-21712)

    An uncontrolled resource consumption flaw was found in python-twisted in the dataReceived() function. This     flaw allows an unauthenticated, remote attacker to send a simple command to use all available memory and     crash the server. (CVE-2022-21716)

    A flaw was found in python-twisted. This vulnerability occurs due to the parsing of illegal constructs in     the twisted.web.http module. The illegal constructs include '+/-' in the Content-Length header, '\n and     \t' etc. Non-conformant parsing leads to a desync if requests pass through multiple HTTP parsers. This     flaw allows a remote attacker to perform an HTTP request smuggling attack. (CVE-2022-24801)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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.

    (CVE-2022-24801)

Note that Nessus relies on the presence of the package as reported by the vendor.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1717 advisory.

    A flaw was found in python-twisted. This vulnerability occurs due to the parsing of illegal constructs in     the twisted.web.http module. The illegal constructs include '+/-' in the Content-Length header, '\n and     \t' etc. Non-conformant parsing leads to a desync if requests pass through multiple HTTP parsers. This     flaw allows a remote attacker to perform an HTTP request smuggling attack. (CVE-2022-24801)

    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)
