CVE-2019-11073

Estado: ModificadaAlta (7.2)—

A Remote Code Execution vulnerability exists in PRTG Network Monitor before 19.4.54.1506 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.
