Amazon Linux 2 : aws-cfn-bootstrap (ALAS-2024-2654)

medium Nessus Plugin ID 209146

Language:

Synopsis

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

Description

The version of aws-cfn-bootstrap installed on the remote host is prior to 2.0-31. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2654 advisory.

 Requests is a HTTP library. Prior to 2.32.0, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. This vulnerability is fixed in 2.32.0. (CVE-2024-35195)

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 aws-cfn-bootstrap' to update your system.
