• Advisory publicly released: Wednesday, 11 August 2010

• Description
  Adobe ColdFusion is a easy to use and very widely adopted Programming language, Procheckup has discovered that the ColdFusion admin console (and various programs within) are vulnerable to multiple directory traversal attacks related to a input parameter. No authentication is needed; all that is needed is that the admin console is accessible to the Internet.
  Notes: Tested on ColdFusion enterprise version7.0 amd version 8.01 running on Windows XP, and Windows 2003 R2 SP2 server and mapped to IIS 6. Procheckup has also confirmed the flaw exists on Linux.
  Defaults were chosen with "server contained installation" "like the earlier versions", and all subcomponents.
  ColdFusion 9 provides an additional layer of filtering to prevent common attacks, preventing the below attack from working. Procheckup recommends however ColdFusion 9 users to apply the ColdFusion 9 patches as Procheckup have found the filtering can be bypassed.
  
  Versions tested and found vulnerable
  ColdFusion MX7 7,0,0,91690 base patches
  ColdFusion MX8 8,0,1,195765 base patches
  ColdFusion MX8 8,0,1,195765 with Hotfix4
  
  Consequences:
  Arbitrary files can be retrieved from the target server, no authentication is required to exploit this vulnerability.
• Proof of concept
  The following demonstrate the traversal flaw:
  *The exploit strings will be published within seven days
• How to fix
  Apply patches as described below, or restrict access to /CIDE/administrator/ by IP address or other similar controls.

  ColdFusion 9
  1. Download CFIDE-9.zip from Adobe.
  2. Make a backup of the {CFIDE-Home}\administrator\cftags\l10n.cfm and {CFIDE-Home}\administrator\cftags\l10n_testing.cfm files.
  3. Extract the files in CFIDE-9.zip to the web root directory that consists of CFIDE folder. The Server Settings > Mappings page in the ColdFusion
  Administrator shows the location of the CFIDE directory in the value for the CFIDE mapping.
  4. Repeat steps 2 and 3 if there are other CFIDE directories identified in any other instances.
  5. Restart all the ColdFusion instances.
