Calibrate Vivotek PT7137 from URL

September 14, 2009/0 Comments/in Hardware, Linux/FreeBSD/by Stefan Helander

The Vivotek PT7137 is a pan-tilt network camera from Vivotek.

After panning and tilting for some time, especially after hitting the boundaries a couple of times, the camera is in need of calibration. You can see this if you have some predefined postition and selecting it doesn’t bring the camera centered to the selected position.

Calibrating the camera can easily be performed by logging in as the administrative account (root) and selecting the Maintenance in the menu. The Calibrate button will immediately calibrate the camera.

However, in some cases you would like to calibrate the camera directly by entering a URL or by using a script.

Siemens Gigaset WLAN camera vulnerability

September 12, 2009/0 Comments/in Hardware/by Stefan Helander

The Siemens Gigaset WLAN camera is vulnerable for unauthorized users to gain access through telnet and ftp by logging in as the user root. The user can log in without any password. When logged in, it is possible to view the cameras configuration file where the administrator password is stored in clear text.

The vulnerability is verified to exist in firmware version 1.27 but might be present in other versions too. At present time there are no updates available from Siemens later than version 1.27.

It is therefore a recommendation to maintain the Siemens Gigaset WLAN camera only on a private network or behind a firewall and to use an administrator password that is not used anywhere else.
