Twisted developers reports :

All HTTP clients in twisted.web.client now raise a ValueError when called with a method and/or URL that contain invalid characters. This mitigates CVE-2019-12387. Thanks to Alex Brasetvik for reporting this vulnerability.

The HTTP/2 server implementation now enforces TCP flow control on control frame messages and times out clients that send invalid data without reading responses. This closes CVE-2019-9512 (Ping Flood), CVE-2019-9514 (Reset Flood), and CVE-2019-9515 (Settings Flood).
Thanks to Jonathan Looney and Piotr Sikora.

twisted.web.http was subject to several request smuggling attacks.
Requests with multiple Content-Length headers were allowed (CVE-2020-10108, thanks to Jake Miller from Bishop Fox and ZeddYu Lu for reporting this) and now fail with a 400; requests with a Content-Length header and a Transfer-Encoding header honored the first header (CVE-2020-10109, thanks to Jake Miller from Bishop Fox for reporting this) and now fail with a 400; requests whose Transfer-Encoding header had a value other than 'chunked' and 'identity' (thanks to ZeddYu Lu) were allowed and now fail with a 400.

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

The version of python-twisted-web installed on the remote host is prior to 12.1.0-7. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1428 advisory.

    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)

    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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4308-1 advisory.

    it was discovered that Twisted incorrectly validated or sanitized certain URIs or HTTP methods. A remote     attacker could use this issue to inject invalid characters and possibly perform header injection attacks.
    (CVE-2019-12387)

    It was discovered that Twisted incorrectly verified XMPP TLS certificates. A remote attacker could     possibly use this issue to perform a machine-in-the-middle attack and obtain sensitive information.
    (CVE-2019-12855)

    It was discovered that Twisted incorrectly handled HTTP/2 connections. A remote attacker could possibly     use this issue to cause Twisted to hang or consume resources, leading to a denial of service. This issue     only affected Ubuntu 18.04 LTS and Ubuntu 19.10. (CVE-2019-9512, CVE-2019-9514, CVE-2019-9515)

    Jake Miller and ZeddYu Lu discovered that Twisted incorrectly handled certain content-length headers. A     remote attacker could possibly use this issue to perform HTTP request splitting attacks. (CVE-2020-10108,     CVE-2020-10109)
