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.
