Vulnerability Description
A vulnerability in the user account management interface of Cisco NX-OS Software could allow an authenticated, local attacker to gain elevated privileges on an affected device. The vulnerability is due to an incorrect authorization check of user accounts and their associated Group ID (GID). An attacker could exploit this vulnerability by taking advantage of a logic error that will permit the use of higher privileged commands than what is necessarily assigned. A successful exploit could allow an attacker to execute commands with elevated privileges on the underlying Linux shell of an affected device. Nexus 7000 and 7700 Series Switches are affected in versions prior to 6.2(22), 8.2(3), and 8.3(2). Nexus 3000 Series Switches are affected in versions prior to 7.0(3)I7(4).
