You would have been aware of the recent tomcat vulnerabilities and Apache's recommendation to upgrade to Tomcat 7.0.90 /8.0.53 tomcat versions. We have got some pointers and tomcat zips in this regard. Please bookmark bit.ly/upgradetomcatchanges for the changes and bit.ly/upgradetomcat for the zips. As of now, bit.ly/upgradetomcat contains tomcat zips for WebNMS (non-ssl) and WebNMS files (compatible with 5.2SP1).
We'll update soon (in the same space) for 5.2SP1 hotfix PPM and ssl configurations.
