CVE-2014-5414
Beckhoff Embedded PC images before 2014-10-22 and Automation Device Specification (ADS) TwinCAT components do not restrict the number of authentication attempts, which makes it easier for remote attackers to obtain access via a brute-force attack.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.80%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
