Hello,

A vulnerability has recently been found in Apache Tomcat. It does not concern all versions.

Is there a way to know which version is installed (depending on the Gateway version from at least 7.7.7).

I’ve found an old post on the forum on this subject but it is about Ignition 7.5.

Regards.

I can’t find anything specific to Tomcat other than under the SSL Context Factory, but you can filter through the logs in the diagnostics page under status for apache.

Through that, I found that 7.9.4 uses Apache Wicket v6.1.1 if that helps at all.

We replaced Tomcat with Jetty in Ignition 7.7

Thanks Kevin, in which case the logs suggest that 7.9.4 uses Jetty 9.3 for example
