Almost 5 dozen security vulnerabilities have been disclosed in devices from 10 operational technology (OT) suppliers owing to what scientists contact are “insecure-by-design techniques.”
Collectively dubbed OT:ICEFALL by Forescout, the 56 issues span as many as 26 system styles from Bently Nevada, Emerson, Honeywell, JTEKT, Motorola, Omron, Phoenix Get in touch with, Siemens, and Yokogawa.
“Exploiting these vulnerabilities, attackers with network obtain to a focus on unit could remotely execute code, alter the logic, documents or firmware of OT gadgets, bypass authentication, compromise credentials, bring about denials of assistance or have a range of operational impacts,” the company reported in a technical report.

These vulnerabilities could have disastrous repercussions contemplating the impacted products and solutions are extensively employed in critical infrastructure industries these types of as oil and gasoline, chemical, nuclear, electrical power generation and distribution, manufacturing, h2o cure and distribution, mining, and building automation.
Of the 56 vulnerabilities found out, 38% permit for compromise of qualifications, 21% enable for firmware manipulation, 14% allow remote code execution, and 8% of flaws empower tampering with configuration information and facts.
Moreover possibly allowing an attacker to source arbitrary code and make unauthorized modifications to the firmware, the weaknesses could also be leveraged to acquire a unit entirely offline and bypass present authentication capabilities to invoke any functionality on the targets.
Additional importantly, broken authentication schemes — like bypass, use of dangerous cryptographic protocols, hardcoded and plaintext qualifications — accounted for 22 of the 56 flaws, indicating “subpar security controls” all through implementation.
In a hypothetical actual-earth circumstance, these shortcomings could be weaponized in opposition to purely natural gas pipelines, wind turbines, or discrete producing assembly lines to disrupt gas transportation, override basic safety options, halt the potential to handle compressor stations, and change the working of programmable logic controllers (PLCs).
But the threats are not just theoretical. A remote code execution flaw influencing Omron NJ/NX controllers (CVE-2022-31206) was, in simple fact, exploited by a point out-aligned actor dubbed CHERNOVITE to build a piece of a refined malware named PIPEDREAM (aka INCONTROLLER).
Complicating risk administration is the growing interconnectedness between IT and OT networks, coupled with the opaque and proprietary nature of several OT methods, not to mention the absence of CVEs, rendering the lingering issues invisible as effectively as retaining this sort of insecure-by-design and style functions for a prolonged time.
To mitigate OT:ICEFALL, it is advisable to find out and stock susceptible devices, implement segmentation of OT property, keep track of network traffic for anomalous exercise, and procure secure-by-style and design goods to beef up the provide chain.
“The progress of current malware focusing on critical infrastructure, these types of as Industroyer2, Triton, and INCONTROLLER, has proven that danger actors are conscious of the insecure by structure mother nature of operational technology and are all set to exploit it to wreak havoc,” the researchers mentioned.
“Regardless of the crucial function that specifications-pushed hardening efforts engage in in OT security, products and solutions with insecure-by-design attributes and trivially damaged security controls ongoing to be certified.”
