CVE-2022-2003
AutomationDirect DirectLOGIC is vulnerable to a specifically crafted serial message to the CPU serial port that will cause the PLC to respond with the PLC password in cleartext.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.77%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
