What is CVE-2017-7899?

An information exposure flaw was identified in Rockwell Automation's Allen-Bradley MicroLogix controllers, specifically versions 16.00 and earlier. The issue arises when user credentials are transmitted to the web server using the HTTP GET method. This practice can inadvertently lead to credentials being logged and made accessible for unauthorized retrieval, risking the integrity and security of user accounts. Ensuring secure transmission methods and implementing proper access controls are critical for safeguarding sensitive information.
