-------------------  
  
  
--- [ Remote File Upload Vulnerability ] ---  
===============================================  
A remote file upload vulnerability is present in LightBlog version 9.5.  
Users without permissions are able to upload any kind of files, also .php; so the attacker can upload their own remote PHP  
shell.  
The file vulnerable is: cp_upload_image.php, and you can find it under the root directory of the blog uploaded. (shown  
in the section PoC).  
  
  
--- [ PoC ] ---  
===============  
http://localhost/light/cp_upload_image.php  
Just look for your PHP shell, upload it (shell.php) and then use it:  
http://localhost/light/images/shell.php  
  
  
--- [ Patch ] ---  
===============  
- Edit the source code.  
- use CHMOD  
- Delete cp_upload_image.php  
- Use the vendor patch.
