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)
