SCADA Vulnerabilities Patched in Industrial Control Software From China
A security researcher discovered several vulnerabilities in industrial control systems software from China that can be exploited remotely.
The vulnerabilities can be used to knock out or take over SCADA (supervisory control and data acquisition) systems from Chinese firm Sunway ForceControl Technology, the U.S. Department of Homeland Securitys Industrial Control Systems Cyber-Emergency Response Team said June 14 in its security advisory. The heap overflow vulnerabilities were discovered in Sunways Force Control and pNetPower products by NSS Labs researcher Dillon Beresford.
Sunway has patched both holes and released software updates for affected systems. ICS-CERT coordinated with Beresford, the China National Vulnerability Database and Sunway to resolve the problem.
A successful exploitation of these vulnerabilities can result in adverse application conditions and ultimately impact the production environment on which the SCADA system is used, said the ICS-CERT advisory.
The security bugs affect the Web server components in Force Control version 6.1 and pNetPower version 6, according to Beresford. The vulnerabilities could be used by a remote attacker to perform a denial-of-service attack on systems running the affected programs and knock it offline, according to the ICS-CERT bulletin. They could also run malicious code against the applications.
Force Control and pNetPower are widely used in Europe and the Americas to control critical infrastructure in the petroleum production, petrochemical, defense, transportation, water, manufacturing and energy industries. Sunway systems are also widely used in China to run weapons systems, utilities and chemical plants. If attackers launch a denial-of-service attack, the networks that control, for example, a petroleum pipeline or other sensitive systems would effectively be shut down, according to the bulletin.
Beresford has uncovered a number of security vulnerabilities in the SCADA systems recently, including issues in the Siemens Step 7 controllers. Chinas infrastructure is extremely vulnerable to cyber-attack, Beresford found, with multiple issues in its systems that can be exploited by cyber-criminals.
The vulnerabilities are particularly worrying because the Stuxnet worm that targeted nuclear facilities in Iran exploited vulnerabilities in Siemens SCADA software. Stuxnet hijacked the control and behavior of programmable logic controller devices that handled nuclear material centrifuges and other systems in the nuclear plant.

For supervisory control and data acquisition SCADA systems. The system gathers information from a remote location or at the factory and a variety of sensor installation is basically. Then, the collected data is sent to the memory of the entire community or a central computer for further processing. The term is used for a variety of small symbols and control, water management, power sector, environmental control, such as large-scale industry production and management solutions business unit.
Network control software and is sent, the sensor receives a signal including SCADA system hardware. These sensors to collect data in the field and sent to the central system. Central system and remote terminal unit (RTU license can 's known as) is the work of the brain. RTU s 'S is a set of logic programming, process data based on them.
