What is CVE-2016-9338?

A vulnerability exists in the Rockwell Automation Allen-Bradley MicroLogix 1100 controller series, due to improper permission assignment affecting critical resources. This flaw allows users with administrative access to potentially remove all other administrative users from the system, which necessitates a factory reset to restore normal web server functionality. Although the device will continue to operate as a controller post-exploitation, the inability to manage user accounts poses a risk to the integrity of the system.
