SOEM version 2.0.0 and earlier contains vulnerabilities where a malicious device on the network can send specially crafted messages that cause the master to write data outside allocated memory boundaries. The software performs arithmetic on message length values without proper validation, allowing negative or extremely large values to bypass safety checks. This can corrupt memory and potentially allow an attacker to execute arbitrary code on the master system.
