The remote host is affected by the vulnerability described in GLSA-202301-02 (Twisted: Multiple Vulnerabilities)

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

The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4074-1 advisory.

  - In Twisted before 19.2.1, twisted.web did not validate or sanitize URIs or HTTP methods, allowing an     attacker to inject invalid characters such as CRLF. (CVE-2019-12387)

  - In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with two     content-length headers, it ignored the first header. When the second content-length value was set to zero,     the request body was interpreted as a pipelined request. (CVE-2020-10108)

  - 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)

When the second content-length value was set to zero,     the request body was interpreted as a pipelined request. (CVE-2020-10108)

  - In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with a     content-length and a chunked encoding header, the content-length took precedence and the remainder of the     request body was interpreted as a pipelined request. (CVE-2020-10109)

  - twisted is an event-driven networking engine written in Python. In affected versions twisted exposes     cookies and authorization headers when following cross-origin redirects.

  - 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.
