The remote programmable logic controller (PLC) device is affected by a
remote code execution vulnerability.
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.

from external networks. See the vendor for further details.

Critical / CVSS Base Score : 10.0
