Estado: ModificadaMedia (6.7)—

A vulnerability in the upgrade component of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, local attacker to install a malicious file when upgrading. The vulnerability is due to insufficient signature validation. An attacker could exploit this vulnerability by providing a crafted upgrade file. A successful exploit could allow the attacker to upload crafted code to the affected device.

CVSS
