Descriptions

A vulnerability in the embedded test subsystem of Cisco IOS Software for Cisco 800 Series Industrial Integrated Services Routers could allow an authenticated, local attacker to write arbitrary values to arbitrary locations in the memory space of an affected device. The vulnerability is due to the presence of certain test commands that were intended to be available only in internal development builds of the affected software. An attacker could exploit this vulnerability by using these commands on an affected device. A successful exploit could allow the attacker to write arbitrary values to arbitrary locations in the memory space of the affected device.

Una vulnerabilidad en el subsistema de pruebas embebido de Cisco IOS Software para routers Cisco 800 Series Industrial Integrated Services podría permitir que un atacante local autenticado escriba valores arbitrarios en ubicaciones arbitrarias en el espacio de memoria de un dispositivo afectado. La vulnerabilidad se debe a la presencia de ciertos comandos de prueba que se supone que debían estar disponibles solo en builds internas de desarrollo del software afectado. Un atacante podría explotar esta vulnerabilidad empleando estos comandos en un dispositivo afectado. Si se explota esta vulnerabilidad con éxito, el atacante podría escribir valores arbitrarios en ubicaciones arbitrarias en el espacio de memoria del dispositivo afectado.
