Descriptions

A vulnerability in the web management interface of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to bypass security protections and upload malicious files to the affected system. This vulnerability is due to improper validation of files uploaded to the web management interface of Cisco FMC Software. An attacker could exploit this vulnerability by uploading a maliciously crafted file to a device running affected software. A successful exploit could allow the attacker to store malicious files on the device, which they could access later to conduct additional attacks, including executing arbitrary code on the affected device with root privileges.

Una vulnerabilidad en la interfaz de administración web del software Cisco Firepower Management Center (FMC) podría permitir a un atacante remoto autenticado omitir las protecciones de seguridad y cargar archivos maliciosos en el sistema afectado. Esta vulnerabilidad es debido a que no se han comprobado apropiadamente los archivos cargados en la interfaz de administración web del software Cisco FMC. Un atacante podría explotar esta vulnerabilidad al cargar un archivo maliciosamente diseñado a un dispositivo que ejecute el software afectado. Una explotación con éxito podría permitir al atacante almacenar archivos maliciosos en el dispositivo, a los que podría acceder más tarde para conducir ataques adicionales, incluyendo la ejecución de código arbitrario en el dispositivo afectado con privilegios de root
