Amazon Linux 2 : python-twisted-web (ALAS-2023-2008)

medium Nessus Plugin ID 173918

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 12.1.0-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2008 advisory.

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

Solution

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