> Hi All,
> I've just run into what I consider a bit of a security issue with the
> SharedResourceRequestTarget. It allows me to load files from the /WEB-INF
> directory (though I have to guess the file names).
> For example, if I see there is some bookmarkable page in the app with the
> name com.myapp.pages.MyBookMarkablePage, I can request the following URL:
> http://www.mydomain.com/resources/com.myapp.pages.MyBookMarkablePage/$up$/$up$/$up$/log4j.xml
> Replace log4j.xml with applicationContext.xml, or any other guesses for
> useful files.
> In both these files it is more than possible that there is sensitive
> information such as database urls and passwords or mail server usernames and
> passwords (though if you use a property configurator in Spring you might be
> lucky since the password is then contained in a .properties file, which is
> blocked by Wicket).
> Of course there may be lots of other sensitive files in WEB-INF.
> I know about the IPackageResourceGuard interface, however, only since today,
> after looking into this problem. :-) I could build my own implementation with
> a default deny policy and open up package resources on a need to have basis.
> However, I REALLY think that Wicket should be secure by default, and a better
> solution to this problem should be found...
> Regards,
> Sebastiaan
