CWE Code: 284
Vulnerability Type: privilege_escalation
CVSS Score: 3.3
CWE Name:  Improper Access Control
Summary: a vulnerability in the fabric infrastructure vlan connection establishment of the cisco nexus 9000 series application centric infrastructure (aci) mode switch software could allow an unauthenticated, adjacent attacker to bypass security validations and connect an unauthorized server to the infrastructure vlan. the vulnerability is due to insufficient security requirements during the link layer discovery protocol (lldp) setup phase of the infrastructure vlan. an attacker could exploit this vulnerability by sending a malicious lldp packet on the adjacent subnet to the cisco nexus 9000 series switch in aci mode. a successful exploit could allow the attacker to connect an unauthorized server to the infrastructure vlan, which is highly privileged. with a connection to the infrastructure vlan, the attacker can make unauthorized connections to cisco application policy infrastructure controller (apic) services or join other host endpoints.
Access Authentication: NONE
Access Complexity: LOW
Access Vector: ADJACENT_NETWORK
Impact (C/I/A): NONE/PARTIAL/NONE
