TITLE

Cisco Catalyst 2960-L Series Switches and CDB-8P Switches access control error vulnerability

Trust: 1.2

sources: CNVD: CNVD-2020-32904 // CNNVD: CNNVD-202006-388

DESCRIPTION

A vulnerability in the 802.1X feature of Cisco Catalyst 2960-L Series Switches and Cisco Catalyst CDB-8P Switches could allow an unauthenticated, adjacent attacker to forward broadcast traffic before being authenticated on the port. The vulnerability exists because broadcast traffic that is received on the 802.1X-enabled port is mishandled. An attacker could exploit this vulnerability by sending broadcast traffic on the port before being authenticated. A successful exploit could allow the attacker to send and receive broadcast traffic on the 802.1X-enabled port before authentication
