Starscream 2.0.3 SSL Pinning Bypass

Posted Apr 21, 2017

Authored by Giuliano Galea, Lukas Futera

WebSocket.swift in Starscream versions 2.0.3 and below allows an SSL Pinning bypass because of incorrect management of the certValidated variable (it can be set to true but cannot be set to false). An attacker can achieve traffic interception from a man-in-the-middle position, first by resetting the TCP connection between the client and server, and afterwards by injecting an SSL server certificates they control.
