According to its self-reported version, Cisco NX-OS Software is affected by a vulnerability. The vulnerability allows an authenticated, local attacker with valid administrator or privilege level 15 credentials to load a virtual service image and bypass signature verification on an affected device. The vulnerability is due to improper signature verification during the installation of an Open Virtual Appliance (OVA) image.
