Descriptions

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an authenticated, remote attacker to inject arbitrary commands that are executed with root privileges. The vulnerabilities are due to improper validation of user-supplied input in the web-based management interface. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to a targeted device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system. To exploit these vulnerabilities, an attacker would need to have valid administrator credentials on an affected device. Cisco has not released software updates that address these vulnerabilities.

Múltiples vulnerabilidades en la interfaz de administración basada en web de Enrutadores Cisco Small Business RV110W, RV130, RV130W, y RV215W, podrían permitir a un atacante autenticado remoto inyectar comandos arbitrarios que son ejecutados con privilegios root. Las vulnerabilidades son debido a una comprobación inapropiada de la entrada suministrada por el usuario en la interfaz de administración basada en web. Un atacante podría explotar estas vulnerabilidades mediante el envío de peticiones HTTP diseñadas hacia un dispositivo apuntado. Una explotación con éxito podría permitir al atacante ejecutar código arbitrario como usuario root en el sistema operativo subyacente. Para explotar estas vulnerabilidades, un atacante necesitaría tener credenciales de administrador válidas en un dispositivo afectado. Cisco no ha publicado actualizaciones de software que aborden estas vulnerabilidades.
