The vulnerability is due to insufficient NX-OS signature verification for software patches. An authenticated, local attacker could exploit this vulnerability to bypass signature verification and load a crafted, unsigned software patch on a targeted device. The attacker would need valid administrator credentials to perform this exploit.
