sent the social network a video proof-of-concept that exploited Mark Zuckerberg's profile and photos.
In fact, the bug allowed hackers to remove photos from
any Facebook profile by exploiting From the Dashboard.
“I can manually modify Photo_id & Owners Profile_id so
that I can able to receive any photo removal link to my inbox. It would be done
without any user’s interaction. And also Facebook will not notify owner if his
photo was removed.” Said Arul Kumar.
Connectikpeople has discovered that, the vulnerability
mainly existed on the mobile domain. This means, if an image wasn’t removed by
the Facebook team, users had the option to send a message with a Photo Removal
Request to the owner. If users sent a fake message, the server automatically
generated a removal link.
