Messenger platform that allows spying on users

Corrected a company Facebook is a security vulnerability in the Messenger platform application for Android, as this vulnerability allowed attackers to spy on users without their knowledge.

The Messenger platform application for Android has been installed on more than one billion Android devices, according to the official page of the application within the Google Play Store.

And I found out (Natalie Silvanovich) Natalie Silvanovich, a security researcher on the AMAN team Project Zero Affiliate of Google, the vulnerability.

The researcher said: The vulnerability exists in the way to implement the WebRTC protocol used by the Messenger platform application To make audio and video calls.

The problem is the SDP protocol, which is part of the WebRTC protocol, and handles the SDP protocol Session data for WebRTC connections.

Silvanovic found that the SDP message for automatic approval of WebRTC connections can be misused without user intervention.
