Title
AutomationDirect DirectLOGIC with Serial Communication Cleartext Transmission
Summary
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. This could allow an attacker to access and make unauthorized changes. This issue affects: AutomationDirect DirectLOGIC D0-06 series CPUs D0-06DD1 versions prior to 2.72; D0-06DD2 versions prior to 2.72; D0-06DR versions prior to 2.72; D0-06DA versions prior to 2.72; D0-06AR versions prior to 2.72; D0-06AA versions prior to 2.72; D0-06DD1-D versions prior to 2.72; D0-06DD2-D versions prior to 2.72; D0-06DR-D versions prior to 2.72;
