An Information Exposure issue was discovered in Rockwell Automation Allen-Bradley MicroLogix 1100 programmable-logic controllers 1763-L16AWA, Series A and B, Version 16.00 and prior versions; 1763-L16BBB, Series A and B, Version 16.00 and prior versions; 1763-L16BWA, Series A and B, Version 16.00 and prior versions; and 1763-L16DWD, Series A and B, Version 16.00 and prior versions and Allen-Bradley MicroLogix 1400 programmable logic controllers 1766-L32AWA, Series A and B, Version 16.00 and prior versions; 1766-L32BWA, Series A and B, Version 16.00 and prior versions; 1766-L32BWAA, Series A and B, Version 16.00 and prior versions; 1766-L32BXB, Series A and B, Version 16.00 and prior versions; 1766-L32BXBA, Series A and B, Version 16.00 and prior versions; and 1766-L32AWAA, Series A and B, Version 16.00 and prior versions. User credentials are sent to the web server using the HTTP GET method, which may result in the credentials being logged. This could make user credentials available for unauthorized retrieval.

Security readout for executives and security teams

This vulnerability can expose credentials for Rockwell Automation Allen-Bradley MicroLogix 1100 and 1400 PLCs because credentials are sent through HTTP GET and may be recorded in web logs. If logs are accessible, unauthorized users could retrieve credentials for industrial control equipment. Exposure is most likely where affected MicroLogix PLC web interfaces are enabled, reachable by users or networks beyond trusted operations staff, or where web/server/proxy logs are broadly accessible. Treat this as a credential exposure risk for operational technology. Prioritize sites using MicroLogix 1100 or 1400 PLCs, especially if management interfaces or logs are accessible outside a tightly controlled operations environment. Mitigation focus: Identify affected MicroLogix 1100 and 1400 PLCs and firmware versions.; Check Rockwell Automation and CISA ICS advisory guidance before applying fixes.; Restrict access to PLC web interfaces to trusted management networks..

Exposure of Sensitive Information to an Unauthorized Actor

Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
