Descriptions

A vulnerability in the web-based management interface of certain Cisco Small Business RV Series Routers could allow an authenticated, remote attacker with administrative privileges to inject arbitrary commands into the underlying operating system. When processed, the commands will be executed with root privileges. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by providing malicious input to a specific field in the web-based management interface of an affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying Linux operating system as the root user.

Una vulnerabilidad en la interfaz de administración basada en web de determinados Cisco Small Business RV Series Routers, podría permitir a un atacante remoto autenticado con privilegios administrativos inyectar comandos arbitrarios en el sistema operativo subyacente. Cuando son procesados, los comandos serán ejecutados con privilegios root. La vulnerabilidad es debido a una comprobación insuficiente de la entrada suministrada por el usuario. Un atacante podría explotar esta vulnerabilidad al proporcionar información maliciosa en un campo específico en la interfaz de administración basada en web de un dispositivo afectado. Una explotación con éxito podría permitir al atacante ejecutar comandos arbitrarios en el sistema operativo Linux subyacente como un usuario root
