ColdFusion 9 Administration Login Bypass (Adobe) 12-15-2013, 06:25 AM

This will be about bypassing the admin login page in the ColdFusion 9 CMS by taking advantage of adminapi.
Adobe ColdFusion versions 9.0, 9.0.1, and 9.0.2 do not properly check the
"rdsPasswordAllowed" field when accessing the Administrator API CFC that is
used for logging in. That CFC "Contains basic Administrator functionality,
including login, logout, the Migration wizard, and the Setup wizard. You must
call the login method before calling any other methods in the Administrator
API."
The login function never checks if RDS is enabled when rdsPasswordAllowed="true".
This means that if RDS was not configured, the RDS user does not have a password
associated with their username. This means by setting rdsPasswordAllowed to
"true", we can bypass the admin login to use the rdsPassword, which in most
cases, is blank.
As long as the attacker has access to
and
Then this is will and can be easily done.
No changes are needed except to substitute
http://www.[site].com/CFIDE/adminapi/administrator.cfc with the proper location
of the adminapi/administrator.cfc
Here's the code to use and save:
Obviously change "[HOSTNAME]" to the name of the site. (Example - www.site.com)
and save the file as whatever you want as long as it has the .html extension.
Now, go to a page on the site that ISN'T /CFIDE/administrator/index.cfc
Open the file you saved with the html code
Click "Submit query" in the html file on your browser
Go to /CFIDE/administrator/index.cfc
Enjoy.
