Security readout for executives and security teams
This issue affects specific Rockwell Automation Allen-Bradley MicroLogix 1100 and 1400 PLCs. The devices may reuse cryptographic nonces, which can let an attacker capture and replay a valid request until the nonce changes. In OT environments, replayed control or management requests can create operational risk. Exposure is limited to organizations using the named MicroLogix 1100 or 1400 PLC models at Version 16.00 or earlier. Risk increases if control-plane traffic can be observed or the controllers are reachable from untrusted networks. Treat this as an OT exposure management issue with uncertain severity. Prioritize sites running the named PLCs where network access is broad or traffic visibility is possible. Business urgency depends on asset criticality and available vendor guidance. Mitigation focus: Inventory MicroLogix 1100 and 1400 PLCs against the listed models and versions.; Check Rockwell Automation and ICS-CERT ICSA-17-115-04 for vendor-directed remediation.; Reduce unnecessary network reachability to affected PLCs while awaiting vendor guidance..

Reusing a Nonce, Key Pair in Encryption
Reusing a Nonce, Key Pair in Encryption represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
