Amazon Linux 2 : python-jinja2 (ALAS-2024-2436)

medium Nessus Plugin ID 190019

Synopsis

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

Description

The version of python-jinja2 installed on the remote host is prior to 2.7.2-3. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2436 advisory.

Jinja is an extensible templating engine. Special placeholders in the template allow writing code similar to Python syntax. It is possible to inject arbitrary HTML attributes into the rendered HTML template, potentially leading to Cross-Site Scripting (XSS). The Jinja `xmlattr` filter can be abused to inject arbitrary HTML attribute keys and values, bypassing the auto escaping mechanism and potentially leading to XSS. It may also be possible to bypass attribute validation checks if they are blacklist-based.
(CVE-2024-22195)

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-jinja2' to update your system.
