A new vulnerability that affects every Android device currently on the market was discovered and published today by Thomas Cannon, an information and security researcher. The hole in the way the Android browser treats Javascript allows a remote attacker to lure an unsuspecting victim to a malicious web page, which then downloads and executes rogue Javascript with access to the local SD card's file system. While the locations of files on the SD card needs to be known by the attacker in advance, it still represents a clear problem due to many popular applications storing data in the same location.
