To exploit this vulnerability, an attacker must control a BGP speaker that has an established trusted peer connection to an affected device that is configured with the address family L2VPN EVPN to receive and process the update message. An attacker could exploit this vulnerability by sending a BGP update message that contains specific EVPN attributes.

This vulnerability is due to the incorrect processing of a BGP update message that contains specific EVPN attributes. Cisco Meraki has released software updates that address this vulnerability.Ī vulnerability in the implementation of the Border Gateway Protocol (BGP) Ethernet VPN (EVPN) functionality in Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. Note: When the attack traffic stops, the Cisco An圜onnect VPN server recovers gracefully without requiring manual intervention. A sustained attack could prevent new SSL VPN connections from being established. A successful exploit could allow the attacker to cause the Cisco An圜onnect VPN server to crash and restart, resulting in the failure of the established SSL VPN connections and forcing remote users to initiate a new VPN connection and re-authenticate. An attacker could exploit this vulnerability by crafting a malicious request and sending it to the affected device.

This vulnerability is due to insufficient validation of client-supplied parameters while establishing an SSL VPN session. A vulnerability in the Cisco An圜onnect VPN server of Cisco Meraki MX and Cisco Meraki Z3 Teleworker Gateway devices could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
