The firmware installed on the remote Allen-Bradley MicroLogix 1400 PLC device is a version prior to 15.004. It is, therefore, affected by a stack-based buffer overflow condition due to improper validation of user-supplied input when handling web requests. An unauthenticated, remote attacker can exploit this to cause a denial of service or to execute arbitrary code.
