Descriptions
A vulnerability in Cisco FXOS Software could allow an authenticated, local attacker with administrative credentials to cause a buffer overflow condition. The vulnerability is due to incorrect bounds checking of values that are parsed from a specific file. An attacker could exploit this vulnerability by supplying a crafted file that, when it is processed, may cause a stack-based buffer overflow. A successful exploit could allow the attacker to execute arbitrary code on the underlying operating system with root privileges. An attacker would need to have valid administrative credentials to exploit this vulnerability.
Una vulnerabilidad en Cisco FXOS Software podría permitir a un atacante local autenticado con credenciales administrativas causar una condición de desbordamiento del búfer. La vulnerabilidad es debido a una comprobación incorrecta de límites de los valores que son analizados desde un archivo específico. Un atacante podría explotar esta vulnerabilidad al suministrar un archivo diseñado que, cuando es procesado, puede causar un desbordamiento del búfer en la región stack de la memoria. Una explotación con éxito podría permitir al atacante ejecutar código arbitrario en el sistema operativo subyacente con privilegios root. Un atacante necesitaría tener credenciales administrativas válidas para explotar esta vulnerabilidad
