A software security hole has been found in the application used by power plants, reports New Scientist.
Penetration-testing firm Core Security discovered a security hole in the Suitelink software from Wonderware.
The application is used to automate operations at oil refineries and production lines, as well as power stations.
New Scientist reports that attackers exploiting the vulnerability could attempt to crash the software by transmitting an outsize data packet to a certain port on the machine running Suitelink.
Wonderware has already issued a security patch for the problem, leaving power stations and others to now update their machines.
A security researcher from Core Security is this week scheduled to reveal a rootkit security hole in the Cisco IOS operating system - that potentially affects all Cisco routers - at a London security conference.
