Steps to Reproduce the Behavior

To understand how this issue manifests, let's outline the steps to reproduce the behavior and confirm that Vireo is indeed using the outdated Tomcat version. While directly reproducing the bug might not be about creating a visible error, it's about verifying the underlying configuration. Here’s how you can check the Tomcat version being used:

1. Go to the Vireo application directory: Navigate to the directory where the Vireo application is deployed on your server.
2. Locate the pom.xml file: This file contains the project's dependencies and configuration, including the Tomcat version.
3. Open pom.xml and check the Tomcat version: Look for the <tomcat.version> property or any dependencies related to Tomcat. If the version specified is 9.0.69, it confirms the bug.
4. Alternatively, check the dependency tree: You can use Maven commands (e.g., mvn dependency:tree) to view the resolved dependencies and verify the Tomcat version being used.
5. Run the application and check the logs: When the application starts, Tomcat logs often display the version information. Reviewing these logs can also confirm the Tomcat version.

By following these steps, you can verify the Tomcat version being used by Vireo and confirm whether it aligns with the current secure version. This is crucial for assessing the risk and planning the necessary updates. Remember, identifying the issue is the first step towards resolving it and ensuring the application's security.
