Amazon Linux 2 : python-webob (ALAS-2025-2726)

medium Nessus Plugin ID 213669

Synopsis

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

Description

The version of python-webob installed on the remote host is prior to 1.2.3-7. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2726 advisory.

WebOb provides objects for HTTP requests and responses. When WebOb normalizes the HTTP Location header to include the request hostname, it does so by parsing the URL that the user is to be redirected to with Python's urlparse, and joining it to the base URL. `urlparse` however treats a `//` at the start of a string as a URI without a scheme, and then treats the next part as the hostname. `urljoin` will then use that hostname from the second part as the hostname replacing the original one from the request. This vulnerability is patched in WebOb version 1.8.8. (CVE-2024-42353)

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-webob' to update your system.
