A security issue exists due to improper handling of CIP Class 32’s request when a module is inhibited on the 5094-IY8 device. It causes the module to enter a fault state with the Module LED flashing red. Upon un-inhibiting, the module returns a connection fault (Code 16#0010), and the module cannot recover without a power cycle.
