medium Nessus Plugin ID 192205

Language:

Synopsis

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

Description

The version of tomcat installed on the remote host is prior to 9.0.83-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2TOMCAT9-2024-012 advisory.

 - Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a single request as multiple requests leading to the possibility of request smuggling when behind a reverse proxy. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fix the issue. (CVE-2023-45648)

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 tomcat' to update your system.
