Run the installer, it will ask some questions you will find your "old" settings in the tomcat9w screenshots or in the relevant config files like http port in the server.xml If the old tomcat version has run a service you need to delete the service I found various diffrent approaches online from diffrent vendors and now i am litle bit uncertain how the "correct" approach would look like.ĭo Backups of anything and do some screenshots of the tomcat9w settings, like memory settings, java Classpath etc. Replace only the files inside the folders /bin and /lib folders.Copy from backup the relevant webapps / certificates etc.Adjust configs like server.xml, web.xml etc.Remove the complete tomcat installation.I found a couple of different ways how to do this minor update and would like to receive your feedback. Before adjusting the tomcat config itself (Disable TLS 1.0 and 1.1, disable weak ciphers etc.) I would like to allign the Tomcat Versions and update them to version 9.0.73. Since installation was done in a couple of years they received since then zero updates and running diffrent versions (9.0.31 on test and 9.0.27 on prod).

It is likely that users upgrading to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations. A number of changes were made to the default AJP Connector configuration in 9.0.31 to harden the default configuration. Users wishing to take a defence-in-depth approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. It is important to note that mitigation is only required if an AJP port is accessible to untrusted users. This vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the web application - processing any file in the web application as a JSP Further, if the web application allowed file upload and stored those files within the web application (or the attacker was able to control the content of the web application by some other means) then this, along with the ability to process a file as a JSP, made remote code execution possible. ![]() It was expected (and recommended in the security guide) that this Connector would be disabled if not required. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped with an AJP Connector enabled by default that listened on all configured IP addresses. If such connections are available to an attacker, they can be exploited in ways that may be surprising. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP connection. When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to Apache Tomcat.
