In Schneider Electric Triconex Tricon MP model 3008 firmware versions 10.0-10.4, when a system call is made, registers are stored to a fixed memory location. Modifying the data in this location could allow attackers to gain supervisor-level access and control system states.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
