Descriptions
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.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Delta Industrial Automation COMMGR. Authentication is not required to exploit this vulnerability.
The specific flaw exists within processing of TCP packets sent to the AHSIM 5x0 Simulator. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of the COMMGR process.
Delta Electronics Delta Industrial Automation COMMGR versions 1.08 and below suffer from a buffer overflow vulnerability.
