> A security vulnerability has been confirmed to exist in all Apache
> Tomcat 4.x releases (including Tomcat 4.0.4 and Tomcat 4.1.10), which
> allows to use a specially crafted URL to return the unprocessed source

> The cause
> ---------
>
> Using the invoker servlet in conjunction with the default servlet
> (responsible for handling static content in Tomcat) triggers this
> vulnerability. This particular configuration is available in the default
> Tomcat configuration.
>
> Workarounds
> -----------
>
> An easy workaround exists for existing Tomcat installations, by
> disabling the invoker servlet in the default webapp configuration.
