Sage Content Management System Bugs Disclose Installation Path and Let Remote Users Conduct Cross-Site Scripting Flaws
|
|
SecurityTracker Alert ID: 1006135 |
|
CVE Reference: GENERIC-MAP-NOMATCH
(Links to External Site)
|
Date: Feb 20 2003
|
Impact: Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network
|
Exploit Included: Yes
|
Version(s): 1.0b3
|
Description: Two vulnerabilities were reported in the Sage content management system. A remote user can determine the installation path and can also conduct cross-site scripting attacks against Sage users.
It is reported that a remote user can request a nonexistent module name to cause the system to display the installation path. Some
demonstration exploit methods are provided:
http://[target]/?mod=some_thing&op=browse
http://[target]/?mod=node&nid=some_thing&op=view
It
is also reported that the $mod variable does not properly filter user-supplied input, allowing a remote user to inject HTML code.
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 Sage 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 is provided:
http://[target]/?mod=<script>alert(document.cookie)</script>&op=browse
|
Impact: A remote user can determine the software installation path. A remote user can access the target user's cookies (including authentication
cookies), if any, associated with the site running Sage, 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.
