PR10-08: Various XSS and information disclosure flaws within Adobe
ColdFusion administration console
Vulnerability found: 17th April 2010

Vendor informed: 19th April 2010

Vulnerability fixed: 8th February 2011

Severity: Medium/High

Description:
Adobe ColdFusion is an easy to use and very widely adopted Programming
language, Procheckup has discovered that the ColdFusion admin console
(and various programs within), are vulnerable to reflective XSS attacks.
The Admin console is normally accessed using a web browser over port
8500 (though this can be changed) or directly mapped onto a web server
directory by proxying cfm extensions.
Note: Tested on ColdFusion enterprise version 8.01 running on Windows
XP, and ColdFusion 7,8,9 running on Windows 2003 R2 SP2 server and
mapped to IIS 6.
Defaults were chosen with "server contained installation", and all
subcomponents.
Versions tested
ColdFusion MX7 7,0,0,91690 base patches
ColdFusion MX8 8,0,1,195765 base patches
ColdFusion MX8 8,0,1,195765 with Hotfix4
ColdFusion MX8 8,0,1,195765 with Hotfix4 and patches from security
Bulletin APSB10-11 shf8010001.jar and CFIDE-801.zip
ColdFusion 9 9,0,0,251028 base patches - ColdFusion 9 includes a simple
list of forbidden tags. So <script> cannot be used.
ColdFusion 9 9,0,0,251028 with Hotfix1 – ColdFusion 9 includes a simple
list of forbidden tags. So <script> cannot be used
The following demonstrate the XSS flaws:-

1) Unauthenticated vanilla XSS - ColdFusion 7 and ColdFusion 8. IE7
browser used.

Consequences:

An attacker may be able to cause execution of malicious scripting code
in the browser of a user who clicks on a link to an exposed ColdFusion
admin site. Such code would run within the security context of the
target domain. This type of attack can result in non-persistent
defacement of the target site, or the redirection of confidential
information (i.e.: session IDs) to unauthorised third parties.



Fix:
Apply patch as described in Adobe bulletin apsb11-04
