Descriptions

InduSoft Web Studio versions prior to 8.1 SP2, and InTouch Edge HMI (formerly InTouch Machine Edition) versions prior to 2017 SP2. A remote attacker could send a carefully crafted packet to exploit a stack-based buffer overflow vulnerability during tag, alarm, or event related actions such as read and write, with potential for code to be executed. If InduSoft Web Studio remote communication security was not enabled, or a password was left blank, a remote user could send a carefully crafted packet to invoke an arbitrary process, with potential for code to be executed. The code would be executed under the privileges of the InduSoft Web Studio or InTouch Edge HMI runtime and could lead to a compromise of the InduSoft Web Studio or InTouch Edge HMI server machine.

InduSoft Web Studio en versiones anteriores a la 8.1 SP2 e InTouch Edge HMI (anteriormente llamado InTouch Machine Edition) en versiones anteriores a la 2017 SP2. Un atacante remoto podría enviar un paquete cuidadosamente manipulado para explotar una vulnerabilidad de desbordamiento de búfer basado en pila durante acciones relacionadas con etiquetas, alarmas o eventos, tales como la lectura y la escritura, con la posibilidad de que se ejecute código. Si la seguridad de las comunicaciones remotas de InduSoft Web Studio no está habilitada o la contraseña se deja en blanco, un usuario remoto podría enviar un paquete cuidadosamente manipulado para invocar un proceso arbitrario o incluso ejecutar código. Este código se ejecutaría bajo los privilegios de los tiempos de ejecución de InduSoft Web Studio o InTouch Edge HMI y podría conducir al compromiso de la máquina del servidor de InduSoft Web Studio o InTouch Edge HMI.
