Two high-severity flaws, discovered in a Fujitsu wireless keyboard set, could allow attackers from a short distance away to eavesdrop on passwords entered into the keyboards, or even fully takeover a victim s system. The Fujitsu Wireless Keyboard Set LX390 desk set consists of a mouse and a keyboard. The wireless keyboard transmits keystrokes to the desktop wirelessly using a 2.4 GHz-range transceiver. Because the data isn t encrypted, it can still be accessed and analyzed by an attacker who is up to 150 feet away.
