Macromedia ColdFusion MX Input Validation Flaw Lets Certain Remote Authenticated Users Access Arbitrary Data on the Server
SecurityTracker Alert ID:  1005908
SecurityTracker URL:  http://securitytracker.com/id/1005908
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Jan 10 2003
Impact:   Disclosure of system information, Disclosure of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): MX
Description:   An input validation vulnerability was reported in Macromedia's ColdFusion MX Enterprise Edition server. A remote authenticated user could create a template that could access arbitrary data on the server.

The vendor reports that the sandbox security features can be circumvented by a template that contains specially crafted arguments for the <cfinclude> and <cfmodule> tags. The software reportedly processes relative file path names for these tags but does not check the Sandbox Security Files/Dirs permissions, allowing arbitrary files on the system to be included by the template. Users that can create templates can exploit this flaw.

Only the MX version is affected, according to the vendor.

Macromedia credits Jochem van Dieten with reporting this flaw.

Impact:   A user with the ability to create templates on the server could gain access to arbitrary files on the system.
Solution:   The vendor has released a patch and indicates you should apply the patch if you use ColdFusion MX Enterprise Edition Sandbox Security and you permit ColdFusion templates from untrusted sources to be executed.

Patch installation instructions are available at:

http://www.macromedia.com/v1/handlers/index.cfm?ID=23638

The flaw will reportedly be fixed in the next release of the ColdFusion MX updater. Users should remove the 48718.jar file when this updater is installed.

Cause:   Access control error, Input validation error
Underlying OS:  Linux (Any), UNIX (HP/UX), UNIX (Solaris - SunOS), Windows (NT), Windows (2000), Windows (XP)

Edition sandbox security issue that allows templates to 
include arbitrary files.

SUMMARY

The <cfinclude> tag and the <cfmodule> tag will accept 
filenames with relative paths as arguments.  CFMX does 
not check the Sandbox Security Files/Dirs permissions 
before including files with these tags.  This could 
allow a template to access unauthorized data using 
these tags.

This does not affect any prior versions of ColdFusion.

~~~~~~~
WHAT CUSTOMERS SHOULD DO:


We strongly encourage customers to download and install 
this patch immediately.
