The version of tomcat installed on the remote host is prior to 7.0.76-10. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2200 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- The SSI printenv command in Apache Tomcat 9.0.0.M1 to 9.0.0.17, 8.5.0 to 8.5.39 and 7.0.0 to 7.0.93 echoes
user provided data without escaping and is, therefore, vulnerable to XSS. SSI is disabled by default. The
printenv command is intended for debugging and is unlikely to be present in a production website.
