Edjpgcom - add comments inside a jpg image

We can sometimes exploit the image upload features and then use file inclusion vulnerabilities to get shell in a server. If the image upload form only allows the .jpg and other valid image files and you locate a local file inclusion vulnerability, you can upload the malicious jpg file containing the PHP code as the commment in it.

In order to add the comment easily inside the jpg images, we can use a small tool called edjpgcom, a jpg commenter. You can drag a jpg image to the edjpgcom icon which will open a window to add comment to the jpg image.
