Synopsis

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

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-743 advisory.

 An issue was discovered in the WEBrick toolkit through 1.8.1 for Ruby. It allows HTTP request smuggling by providing both a Content-Length header and a Transfer-Encoding header, e.g., GET /admin HTTP/1.1\r\n inside of a POST /user HTTP/1.1\r\n request. NOTE: the supplier's position is Webrick should not be used in production. (CVE-2024-47220)

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 ruby3.2 --releasever 2023.6.20241028' to update your system.
