Amazon Linux 2 : nginx (ALASNGINX1-2023-004)

medium Nessus Plugin ID 181953

Language:

Synopsis

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

Description

The version of nginx installed on the remote host is prior to 1.18.0-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2NGINX1-2023-004 advisory.

 NGINX before 1.17.7, with certain error_page configurations, allows HTTP request smuggling, as demonstrated by the ability of an attacker to read unauthorized web pages in environments where NGINX is being fronted by a load balancer. (CVE-2019-20372)

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 nginx' to update your system.
