Horner Automation’s RCC 972 firmware version 15.40 contains global variables. This could allow an attacker to read out sensitive values and variable keys from the device.
The code is structured in a way that relies too much on using or setting global variables throughout various points in the code, instead of preserving the associated information in a narrower, more local context.
