CVE-2018-7522 is a memory-handling vulnerability affecting Schneider Electric Triconex Tricon MP Model 3008 safety instrumented systems running firmware versions 10.0 through 10.4. During a system call, processor registers are stored to a fixed memory location. Because this location can be modified, an attacker with the necessary access can tamper with the saved register state and influence privileged execution flow. Successful exploitation can result in supervisor-level access on the controller and unauthorized control over system states, undermining the integrity of the safety instrumented system.
