Security readout for executives and security teams
This flaw affects Rockwell Automation Allen-Bradley MicroLogix 1100 and 1400 PLCs. The devices do not penalize repeated wrong password attempts, making password guessing materially easier if an attacker can reach the device over the network. Because PLC compromise can affect industrial operations, treat confirmed exposure as urgent. Organizations using listed MicroLogix 1100 or 1400 PLC models at Version 16.00 or earlier are potentially exposed, especially where device management or programming access is reachable from business networks, remote access paths, or the internet. High priority for industrial environments using these PLCs. The vulnerability is old but severe, and legacy PLCs often remain in service. Prioritize assets that are reachable from less-trusted networks or support critical production, safety, or utility processes. Mitigation focus: Inventory MicroLogix 1100 and 1400 PLCs and record exact catalog, series, and version.; Check Rockwell Automation and CISA advisory guidance for approved updates or compensating controls.; Restrict PLC access to trusted engineering workstations and required management paths only..

Improper Restriction of Excessive Authentication Attempts
Improper Restriction of Excessive Authentication Attempts represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
