Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-012 advisory.

A flaw was found in wget. If wget sends an Authorization header as part of a query and receives an HTTP REDIRECT to a third party in return, the Authorization header will be forwarded as part of the redirected request. This issue creates a password leak, as the second server receives the password. The highest threat from this vulnerability is confidentiality. (CVE-2021-31879)

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 'dnf update wget --releasever=2023.0.20230222 ' to update your system.
