LINE for Android version 5.0.2 and earlier and LINE for iOS version 5.0.0 and earlier are vulnerable to MITM (man-in-the-middle) attack since the application allows non-SSL/TLS communications. As a result, any API may be invoked from a script injected by a MITM (man-in-the-middle) attacker.
The product establishes a communication channel with an endpoint and receives a message from that endpoint, but it does not sufficiently ensure that the message was not modified during transmission.
