Amazon Linux 2 : tomcat (ALASTOMCAT9-2023-004)

critical Nessus Plugin ID 182056

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 9.0.65-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2TOMCAT9-2023-004 advisory.

- A Spring MVC or Spring WebFlux application running on JDK 9+ may be vulnerable to remote code execution (RCE) via data binding. The specific exploit requires the application to run on Tomcat as a WAR deployment. If the application is deployed as a Spring Boot executable jar, i.e. the default, it is not vulnerable to the exploit. However, the nature of the vulnerability is more general, and there may be other ways to exploit it. (CVE-2022-22965)

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.
