(Links to External Site)
|
Date: Oct 24 2002

Impact: Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network
|
Exploit Included: Yes

Description: An input validation vulnerability was reported in Mojo Mail, a mailing list manager. A remote user can conduct cross-site scripting attacks against Mojo Mail users.
It is reported that Mojo Mail does not properly filter HTML from user-supplied inputs during sign-up requests.
A remote user
can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the
target user's browser. The code will originate from the site running the Mojo Mail software and will run in the security context
of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any,
associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site
acting as the target user.
A demonstration exploit URL is provided:
http://[target host]/cgi-bin/mojo/mojo.cgi?flavor=subscribe&email=%
3Cscript%3Ealert%28%22XSS%
20Vuln.%22%29%3C%2Fscript%
3E&list=skazat_design_newsletter&submit=Submit
|
Impact: A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the
Mojo Mail software, access data recently submitted by the target user via web form to the site, or take actions on the site acting
as the target user.

Subject: XSS vulnerability in Mojo Mail Sign-Up Form
|
Heya, this is my first post here so go easy on me plz. I posted about this
on the Mojo Bug Tracker ages ago and it's just been ignored, and besides,
Im losing faith in reporting to the vendor, PHP Arena took the credit for
an XSS bug I found in their paFileDB. But anyway, Mojo Mail doesn't filter
sign-up requests, here's an example on Mojo's site:
http://mojo.skazat.com/cgi-bin/mojo/mojo.cgi?flavor=subscribe&email=%
3Cscript%3Ealert%28%22XSS%20Vuln.%22%29%3C%2Fscript%
3E&list=skazat_design_newsletter&submit=Submit
I don't know if I'm supposed to say more but it's just XSS, I think that's
it?
