The flaw reportedly also exists on Android devices.

Wright first revealed the difficulty whereas the usage of iExplorer to browse information on his iPhone, discovering that the facebook .plist file keeps the whole oAuth key and secret needed to get admission to his account in undeniable textual content. Working with a friend, Wright was in a position to exhibit that simply transferring that .plist file to every other tool granted that tool get right of entry to to his fb account.

Scoopz then opened Draw one thing on his iPad which logged him straight into my account where he despatched some photos again to my chums.
