Bypass Facebook Account Password Just Send A Link

Hack Facebook AccountsA security researcher found a significant cross-site request forgery (CSRF) vulnerability in popular social media that could have allowed to bypass a facebook account password to simply send a link to the targeted users.

This is possible because of a vulnerable endpoint which takes another given endpoint selected by the attacker along with the parameters and makes a POST request to that endpoint after adding the fb_dtsg parameter.
Also, this endpoint is located under the main domain www.facebook.com which makes it easier for the attacker to trick his victims to visit the URL. source 

Security Researcher “Samm0uda” found the vulnerability behind he detected a vulnerability endpoint “https://www.facebook.com/comet/dialog_DONOTUSE/?url=GLOBALHACKNEWS” where GLOBALHACKNEWS is the endpoint with parameters where the POST request is going to be made to bypass CSRF protections and takeover victim’s account then hacker change or delete their profile picture, and even trick users into deleting their entire accounts.

“Samm0uda” informed the vulnerability with the details of his exploit to on 26 January 2019. The social media fixed  the issue it on 31 January 2019, rewarding the researcher with  $25,000 Bounty Awarded by Facebook
