Rockwell Automation FLEX I/O EtherNet/IP Adapters version 2.012 are affected by two vulnerabilities. CVE-2026-0647 allows unauthenticated account takeover via the embedded web server, while CVE-2026-0646 enables a denial-of-service condition through malformed CIP protocol requests.
Rockwell Automation RSLinx Classic versions 4.50.00 and prior contain an out-of-bounds read and stack-based buffer overflow vulnerability (CVE-2020-13573). Successful exploitation by a remote attacker can lead to a denial of service condition where the application becomes unresponsive, or potentially allow for remote code execution.
Rockwell Automation Logix 5370 and 5570 controllers are affected by a high-severity denial-of-service vulnerability (CVE-2026-11317, CVSS 8.7) triggered by crafted Common Industrial Protocol (CIP) messages. Successful exploitation results in a major nonrecoverable fault (MNRF) due to improper resource shutdown or release, requiring a manual program download to restore operations.
The 2026 FIFA World Cup presents a massive, multi-jurisdictional attack surface threatened by state-nexus disruptive operations and financially motivated cybercrime. Key risks include Iran-aligned actors targeting municipal OT infrastructure, pro-Russian hacktivists launching high-volume DDoS attacks against tournament services, and cybercriminals deploying ransomware against the hospitality supply chain.
Iranian-affiliated APT actors are actively targeting internet-exposed programmable logic controllers (PLCs), specifically Rockwell Automation devices, across multiple U.S. critical infrastructure sectors. The attackers utilize native configuration software and Dropbear SSH to manipulate project files and HMI displays, leading to operational disruptions and financial losses.
