CVE-2011-4861
The modbus_125_handler function in the Schneider Electric Quantum Ethernet Module on the NOE 771 device (aka the Quantum 140NOE771* module) allows remote attackers to install arbitrary firmware updates via a MODBUS 125 function code to TCP port 502.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.04%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
