Delta Industrial Automation COMMGR from Delta Electronics versions 1.08 and prior with accompanying PLC Simulators (DVPSimulator EH2, EH3, ES2, SE, SS2 and AHSIM_5x0, AHSIM_5x1) utilize a fixed-length stack buffer where an unverified length value can be read from the network packets via a specific network port, causing the buffer to be overwritten. This may allow remote code execution, cause the application to crash, or result in a denial-of-service condition in the application server.

Delta Industrial Automation COMMGR de Delta Electronics en versiones 1.08 y anteriores con sus simuladores PLC (DVPSimulator EH2, EH3, ES2, SE, SS2 y AHSIM_5x0, AHSIM_5x1) utiliza un búfer de pila de longitud fija en el que se puede leer un valor de longitud no verificado desde los paquetes de red mediante un puerto de red específico, provocando la sobrescritura del búfer. Esto puede permitir la ejecución remota de código, provocando el cierre inesperado de la aplicación o resultando en una condición de denegación de servicio (DoS) en el servidor de la aplicación.
