Amazon Linux 2 : python-requests (ALAS-2023-2110)

critical Nessus Plugin ID 178529

Language:

Synopsis

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

Description

The version of python-requests installed on the remote host is prior to 2.6.0-10. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2110 advisory.

 A flaw was found in the Python-requests package, where it is vulnerable to potentially leaking Proxy- Authorization headers to destination servers, specifically during redirects to an HTTPS origin. This is a product of how rebuild_proxies is used to recompute and reattach the Proxy-Authorization header to requests when redirected. This behavior only affects proxied requests when credentials are supplied in the URL user information component (for example, https://username:password@proxy:8080). (CVE-2023-32681)

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-requests' to update your system.
