Description

According to its model number and software version, the remote host is a Xerox Document Centre or WorkCentre device with an embedded web server that could allow unauthorized access to the web server directory structure, which in turn could enable a remote attacker to gain access rights and to make unauthorized changes to the device's system configuration.
