Subject Re: Url rewriting of .action to .jsp
Date Mon, 23 Sep 2013 15:42:59 GMT
Hi all,
I'm using DMI to call "input" method extensively,
almost in every Edit*Action.
I call it with ParamsPrepareParams stack.

I fully understand that allowing DMI is a security problem.
But maybe some kind of balance could be achevied.
White listing with annotations would not be bad for me
also maybe letting call only input (or similar) method by default
would not cause to much of a security problem?

I'm not saying that i will drop S2
if DMI will be disabled,
but sure it will make me rewrite all my edit actions.

Best greetings,
Paweł Wielgus.
