Updated: Mar 13 2007
|
Original Entry Date: Dec 11 2006

Impact: Disclosure of system information, Modification of system information

Fix Available: Yes
Vendor Confirmed: Yes

Advisory: Adobe Advisory

Version(s): MX 7, possibly MX6

Description: A vulnerability was reported in Adobe ColdFusion. A remote user can bypass cross-site scripting protections. A remote user can determine the installation path. A remote user can determine the internal IP address.
A remote user can insert a %00 character within a '<script>' tag to bypass cross-site scripting protections.
A demonstration exploit
URL is of the following form:
http://[target]/CFIDE/componentutils/cfcexplorer.cfc?
method=getcfcinhtmtestl&name=CFIDE.adminapi.administrator&
path=/cfide/adminapi/a
dministrator.cfctest">
<%00script>alert(document.domain)</script>
If a global error handler has not been defined, a remote user
can submit an invalid request to cause the system to disclose the installation path. A request for an existing file that has a
file extension that is not processed by the web server can trigger the flaw. The following extensions can be exploited:
.jws
.cfm
.cfml
.cfc
A
remote user can also determine the internal network IP address by making a request to the following page without a host value:
/CFIDE/administrator/login.cfm
The
vendor was notified on November 11, 2006.
Brett Moore of Security-Assessment.com discovered these vulnerabilities.

Impact: A remote user can bypass cross-site scripting protections.
A remote user can determine the installation path.
A remote user can determine the internal IP address.

Subject: [Full-disclosure] [SBDA] - ColdFusion MX7 - Multiple Vulnerabilities
|
Just clearing stuff out before Christmas.
========================================================================
= ColdFusion MX7 - Multiple Vulnerabilities
= Vendor Website:
= http://www.Adobe.com
= Affected Software:
= ColdFusion MX7 (and possibly MX6)
= Public disclosure on Monday December 11, 2006
========================================================================
== Overview ==
This advisory discloses three separate security issues in ColdFusion
MX7.
* Server Path Disclosure *
It is possible to cause the server to disclose the local path by making
an invalid request. This information could be used to aide in other file
or path based attacks.
The request must be for an existing file, that has an extension not
handled by the web server. (ie: not asp,aspx).
The request must be terminated with either of the following;
/.jws
/.cfm
/.cfml
/.cfc
Some example requests are;
http://serverip/page1.htm/a.cfm
http://serverip/CFIDE/administrator/analyzer/img/minus.gif/a.cfm
http://serverip/jrunscripts/jrun.ini/a.cfm
http://serverip/jrunscripts/jrunserver.store/a.cfm
http://serverip/jrunscripts/readme.txt/a.cfm
This has been confirmed against installs that do NOT have debugging or
robust exception information turned on.
Sending a request in this format returns a message similar to;
Error parsing the Tag Library Descriptor
file:/d:/sekretpath/hidden/page1.htm/..
* Internal IP Address Disclosure *
It is possible to cause the server to disclose the internal network IP
address of the host. This information could be used to aide in other
network based attacks.
Making a request to the /CFIDE/administrator/login.cfm page WITHOUT
supplying a host, will result in the internal IP address of the
server to be disclosed as part of an href tag.
------------------------------------------------------------------
GET /CFIDE/administrator/login.cfm HTTP/1.0
HTTP/1.1 200 OK
Server: Microsoft-IIS/5.1
Date: Thu, 09 Nov 2006 05:44:02 GMT

<LINK REL="SHORTCUT ICON"
href="http://INTERNALADDRESS:80/CFIDE/administrator/favicon.ico">
------------------------------------------------------------------
* Cross Site Scripting Protection Bypass *
ColdFusion MX7 appears to have built in protection against cross
site scripting attacks, and will replace <script> tags with
<invalid tag>.
Example URL that is converted to a 'safe' format;
http://server/CFIDE/componentutils/cfcexplorer.cfc?
method=getcfcinhtmtestl&name=CFIDE.adminapi.administrator&
path=/cfide/adminapi/administrator.cfctest">
<script>alert()</script>
By inserting a %00 within the <script> tag, it is possible to still
conduct cross site scripting attacks against users of
Internet Explorer.
Example URL that will have script executed;
http://server/CFIDE/componentutils/cfcexplorer.cfc?
method=getcfcinhtmtestl&name=CFIDE.adminapi.administrator&
path=/cfide/adminapi/administrator.cfctest">
<%00script>alert(document.domain)</script>
== Solutions ==
Currently, the issues outlined in the report are being considered for
the next major version of ColdFusion - the release date is currently not
finalized. There is currently no plan to release security bulletins for
any of the issues from the report
