Open a web page and put in the Address area: javascript:window.parent.close(); and press return.
The window will close. Scary.
Try this:
javascript:alert(document.cookie)
Displays the cookie information for a page, so you can see what a site is actually storing about you and your behaviour.
javascript:void(document.cookie="MessUpTheCookie") changes the cookie.
Now if your site was using cookies to do security or credit cards you are in BIG trouble my friend. Spend a few minutes checking this out with your developers it could saver you a lot of cash.
Form fields:
javascript:alert(document.forms[0]) can return [object]. If so then try:
javascript:alert(document.forms[0].DocTitle.value); alert(document.forms[0].Abstract.value);
displays the value of the field: DocTitle and Abstract. Scaryish especially if it was a field like Readers or Authors...
What does :
javascript:document.forms[0].DocTitle.value=' http://www.AdFos.com'; do?
What about:
javascript:document.forms[0].DocTitle.value=' http://www.AdFos.com'; return false; do?
What about in an older browser?
Submit and action type:
Would javascript:void(document.forms[0].action="GET") do damage?
javascript:void(document.forms[0].submit()) will save a web form even if you have hidden the Save button!
What about with LiveLink and CORBA ?
This could basically give a user access to your server databases and views...
If I find any other problems with this I will add to this document.
