  - A Remote Code Execution vulnerability exists that allows attackers to execute code due to insufficient
    sanitization when passing arguments to the HttpTransactionSensor.exe binary. In order to exploit the
    vulnerability, remote authenticated administrators need to create a new HTTP Transaction Sensor and set
    specific settings when the sensor is executed. (CVE-2019-11073)
