CWE Code: 264
Vulnerability Type: privilege_escalation
CVSS Score: 7.2
CWE Name:  Permissions Privileges and Access Controls
Summary: a vulnerability in the bash shell implementation for cisco nx-os software could allow an authenticated, local attacker to escalate their privilege level by executing commands authorized to other user roles. the attacker must authenticate with valid user credentials. the vulnerability is due to the incorrect implementation of a bash shell command that allows role-based access control (rbac) to be bypassed. an attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the bash prompt. a successful exploit could allow the attacker to escalate their privilege level by executing commands that should be restricted to other roles. for example, a dev-ops user could escalate their privilege level to admin with a successful exploit of this vulnerability.
Access Authentication: NONE
Access Complexity: LOW
Access Vector: LOCAL
Impact (C/I/A): COMPLETE/COMPLETE/COMPLETE
