3 New Vulnerabilities Affect OT Products from German Companies Festo and CODESYS

3 New Vulnerabilities Affect OT Products from German Companies Festo and CODESYS

Nov 30, 2022
Researchers have disclosed details of three new security vulnerabilities affecting operational technology (OT) products from CODESYS and Festo that could lead to source code tampering and denial-of-service (DoS). The vulnerabilities, reported by Forescout Vedere Labs, are the latest in a long list of flaws collectively tracked under the name  OT:ICEFALL . "These issues exemplify either an insecure-by-design approach — which was usual at the time the products were launched – where manufacturers include dangerous functions that can be accessed with no authentication or a subpar implementation of security controls, such as cryptography," the researchers  said . The most critical of the flaws is  CVE-2022-3270  (CVSS score: 9.8), a critical vulnerability that affects Festo automation controllers using the Festo Generic Multicast (FGMC) protocol to reboot the devices without requiring any authentication and cause a denial of service (DoS) condition. Another DoS shortcoming i

Your OT Is No Longer Isolated: Act Fast to Protect It

Nov 04, 2022
Not too long ago, there was a clear separation between the operational technology (OT) that drives the physical functions of a company – on the factory floor, for example – and the information technology (IT) that manages a company's data to enable management and planning.  As IT assets became increasingly connected to the outside world via the internet, OT remained isolated from IT – and the rest of the world. However, the spread of Industrial IoT (IIoT) as well as the need for constant monitoring and tracking information from manufacturing and assembly lines mean the connection between IT and OT systems has greatly expanded. OT is no longer isolated. OT is now just as exposed to the outside world as IT is. What does this mean for OT security, where hard-to-access devices needed for 24/7 production are difficult to patch? Let's take a look. The Air Gap Is Gone Not so long ago, any data exchange between IT and OT operated via a "sneaker net." An operator would p
New Evil PLC Attack Weaponizes PLCs to Breach OT and Enterprise Networks

New Evil PLC Attack Weaponizes PLCs to Breach OT and Enterprise Networks

Aug 16, 2022
Cybersecurity researchers have elaborated a novel attack technique that weaponizes programmable logic controllers ( PLCs ) to gain an initial foothold in engineering workstations and subsequently invade the operational technology (OT) networks. Dubbed " Evil PLC " attack by industrial security firm Claroty, the issue impacts engineering workstation software from Rockwell Automation, Schneider Electric, GE, B&R, Xinje, OVARRO, and Emerson. Programmable logic controllers are a crucial component of industrial devices that control manufacturing processes in critical infrastructure sectors. PLCs, besides orchestrating the automation tasks, are also configured to start and stop processes and generate alarms. It's hence not surprising that the entrenched access provided by PLCs have made the machines a focus of sophisticated attacks for more than a decade, starting from  Stuxnet to PIPEDREAM  (aka INCONTROLLER), with the goal of causing physical disruptions.  "The
Researchers Disclose 56 Vulnerabilities Impacting OT Devices from 10 Vendors

Researchers Disclose 56 Vulnerabilities Impacting OT Devices from 10 Vendors

Jun 21, 2022
Nearly five dozen security vulnerabilities have been disclosed in devices from 10 operational technology (OT) vendors due to what researchers call are "insecure-by-design practices." Collectively dubbed  OT:ICEFALL  by Forescout, the 56 issues span as many as 26 device models from Bently Nevada, Emerson, Honeywell, JTEKT, Motorola, Omron, Phoenix Contact, Siemens, and Yokogawa. "Exploiting these vulnerabilities, attackers with network access to a target device could remotely execute code, change the logic, files or firmware of OT devices, bypass authentication, compromise credentials, cause denials of service or have a variety of operational impacts," the company said in a technical report. These vulnerabilities could have disastrous consequences considering the impacted products are widely employed in critical infrastructure industries such as oil and gas, chemical, nuclear, power generation and distribution, manufacturing, water treatment and distribution, min
