A security vulnerability involving some HP printer models makes users open to hacking attack.
The bug in the Toolbox software installed with HP's Color LaserJet 2500 and 4600 printers creates a means for attackers to pinch valuable information. When the Toolbox is left in a default configuration hackers might be able to steal files from a Windows PC connected to these printers. HP advises users to upgrade their Toolbox software to version 3.1 to guard against possible attacks.
