A vulnerability in Rockwell Automation Allen-Bradley MicroLogix 1400 Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on a targeted device.
The vulnerability is due to a stack-based buffer overflow condition in the affected devices. An attacker could exploit this vulnerability to execute arbitrary code on a targeted device. A successful exploit could cause the targeted device to stop functioning, resulting in a DoS condition.
Rockwell Automation has confirmed the vulnerability and released a firmware update.
