It would be nice to have a option (-D or something similar) to hide the version information of the running jenkins master instance.

This would avoid (make it harder) for hackers to attack a jenkins instance which has known vulnerabilities. 

Currently the website shows in the footer the current running jenkins version.

I would like to hide this information or overwrite it with "-1" or similar. Such option can be set a java system property.

We are running jenkins master as WAR archive inside a tomcat container. So the java system property would be the best way to solve this.

PS: feel free to change the component .. there seems to be no component for jenkins master or the general UI available.
