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.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

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)
