TITLE

Cisco Catalyst 4500 Series and 4500-X Series switch error handling vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-003565

DESCRIPTION

A vulnerability in the Bidirectional Forwarding Detection (BFD) offload implementation of Cisco Catalyst 4500 Series Switches and Cisco Catalyst 4500-X Series Switches could allow an unauthenticated, remote attacker to cause a crash of the iosd process, causing a denial of service (DoS) condition. The vulnerability is due to insufficient error handling when the BFD header in a BFD packet is incomplete. An attacker could exploit this vulnerability by sending a crafted BFD message to or across an affected switch. A successful exploit could allow the attacker to trigger a reload of the system. This vulnerability affects Catalyst 4500 Supervisor Engine 6-E (K5), Catalyst 4500 Supervisor Engine 6L-E (K10), Catalyst 4500 Supervisor Engine 7-E (K10), Catalyst 4500 Supervisor Engine 7L-E (K10), Catalyst 4500E Supervisor Engine 8-E (K10), Catalyst 4500E Supervisor Engine 8L-E (K10), Catalyst 4500E Supervisor Engine 9-E (K10), Catalyst 4500-X Series Switches (K10), Catalyst 4900M Switch (K5), Catalyst 4948E Ethernet Switch (K5). Cisco Bug IDs: CSCvc40729. Vendors have confirmed this vulnerability Bug ID CSCvc40729 It is released as.Service operation interruption (DoS) There is a possibility of being put into a state. Both IOS and IOSXESoftware are operating systems developed for Cisco network devices. The vulnerability stems from a program not adequately handling errors. Cisco IOS and IOS XE Software are prone to a remote denial-of-service vulnerability. Attackers can exploit this issue to cause a reload of the device, resulting in a denial-of-service condition
