Summary: The 4th generation IrisAccessaC/ 7000 series iris recognition solution offered
by Iris ID provides fast, secure, and highly accurate, non-contact identification
by the iris of the eye. The iCAM7000's versatility and flexibility allows for easy
integration with many Wiegand and network based access control, time and attendance,
visitor management and point of sale applications.

The iCAM4000 or 4010 with embedded smart card is the best-selling model in the IrisAccess
4000 range. Simultaneous two-eye capture, face-badging camera, motorized height adjust,
iCAM4000 is easily configured for use in a kiosk as well as in applications where a traditional
wall-mount is used.

Desc: The Iris ID IrisAccess iCAM4000/7000 series suffer from a use of hard-coded credentials.
When visiting the device interface with a browser on port 80, the application loads an applet
JAR file 'ICAMClient.jar' into user's browser which serves additional admin features. In the
JAR file there is an account 'rou' with password 'iris4000' that has read and limited write
privileges on the affected node. An attacker can access the device using these credentials
starting a simple telnet session on port 23 gaining access to sensitive information and/or
FTP access on port 21 (with EVERYTHING allowed) and uploading malicious content.

74:  #                       the user has access to the WHOLE SUBTREE,
75:  #                       if the server has access to it
