7 months already open hole in industrial software from Siemens hit the Netherlands. A HP G62 screen system at TNO was wide open.
It just revealed 0-day hole in the remote access to Siemens' factory management software SIMATIC is the worldwide abuse. Industrial systems with so-called SCADA software (Supervisory Control And Data Acquisition) to remotely manage remote access by default open with default password also automatically takes effect when a user enters invalid password.
Netherlands, Delft
Open systems are so over the Internet to find blogs the security researcher who, after seven months silence his discovery now revealed. He thereby provides a link to port scanning site Shodan . It has more than one year ago served as Stuxnet scanner . Worldwide HP G71 screen there are many more systems to be found by simply Googling to the text message that the web interface is on.
Through the SCADA-specific site are outstanding Shodan Simatic systems available. Inspection by Macworld did a Dutch IP address on, what a lookup in the name of research institute TNO. Spokesman Martin L?rtzer reacts quickly to report this vulnerability. It confirms that the IP address of TNO and light their own security people at the institute.
Equal offline
ICT professionals who do not take half measures and block the entire IP address of the HP G72 screen underlying Simatic system. This takes TNO at once the three 'types' of this vulnerability. The Siemens software enables all come three open access services: Web, VNC (remote desktop) and Telnet. Macworld yesterday afternoon has been tested to verify only the first and immediately informed TNO.
All three services are separate as authentication is concerned. Adjusting username / password for one remote access service will not impact the other. The web interface offers enough options to the underlying system to drive them to read the logs and the whole off.
Climate Control
TNO before the blockade of the open web interface is checked what the actual system. In order to estimate the impact of the blockade would be L?rtzer puts out. "It's not a critical system," he knows to report. "It is a climate control for." In such a space can RIP measurements with HP Mini 110 screen different temperatures and humidity.
It was not that great around here RIP was to "freeze", the spokesman still comfortable. However, it was through the open web interface to see what kind of industrial equipment to operate thus: a 10-inch touch panel for climate control equipment used. This so-called HMI panel can be used to operate various industrial equipment: in factories, power plants and environmental chambers.
System Info, Web server logs
The open web interface also gave detailed information about the underlying system. As the HP Mini 210 screen firmware and bootloader version has the batch commands have been run when operators have logged.
The built-in file browser of the web interface allows access to the folder where the actual webserver. It also leads to any inserted memory cards and USB keys. Then the logs are, parameters, configuration files, history and various other files to operate the industrial system.
1-click pwnen
Furthermore, all directly through the web interface all "user data administration" in a handy file to download, but upload. An attacker may be thus obtained. Pwl file HP DM1 screen is provided with its own login account and upload again. Finally, the configuration (called " recipes ") of the industrial equipment available: it can be downloaded, delete, replace and supplement.
