SecurityTracker Alert ID: 1009966
|
|
CVE Reference: GENERIC-MAP-NOMATCH
(Links to External Site)
|
Date: Apr 28 2004
|
Impact: Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
|
Exploit Included: Yes
|
Version(s): 3.1
|
Description: An input validation vulnerability was reported in paFileDB. A remote user can conduct cross-site scripting attacks and also determine the installation path.
DarkBicho reported that the category function does not filter HTML code from user-supplied input in the 'id' parameter. 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 paFileDB 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://localhost/pafiledb.php?action=category&id='<script>alert(document.cookie);</script>
It
is also reported that a remote user can request the following type of URL to determine the installation path:
http://site/includes/admin/login.php?formname=DarkBicho&
formpass=DarkBicho
&B1=%3E%3E+Log+In+%3C%3C&action=admin&login=do
The vendor has reportedly been notified.
|
Impact: A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the
paFileDB 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.
A remote user can determine the installation path.
