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.

This issue makes it more difficult to maintain the product, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. It also might make it easier to introduce vulnerabilities.
