Amazon Linux 2 : python-urllib3 (ALAS-2020-1446)

critical Nessus Plugin ID 138048

Synopsis

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

Description

The version of python-urllib3 installed on the remote host is prior to 1.25.7-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1446 advisory.

urllib3 before version 1.23 does not remove the Authorization HTTP header when following a cross-origin redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the Authorization header to be exposed to unintended hosts or transmitted in cleartext. (CVE-2018-20060)

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

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-urllib3' to update your system.
