Amazon Linux 2 : jetty (ALAS-2024-2408)

medium Nessus Plugin ID 187843

Language:

Synopsis

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

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2408 advisory.

 - For Eclipse Jetty versions <= 9.4.40, <= 10.0.2, <= 11.0.2, it is possible for requests to the ConcatServlet with a doubly encoded path to access protected resources within the WEB-INF directory. For example a request to `/concat?/%2557EB-INF/web.xml` can retrieve the web.xml file. This can reveal sensitive information regarding the implementation of a web application. (CVE-2021-28169)

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 jetty' to update your system.
