Amazon Linux 2 : python-twisted-web (ALAS-2020-1428)

critical Nessus Plugin ID 136751

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

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.

Solution

Run 'yum update python-twisted-web' to update your system.
