TITLE

Cisco IOS Software for Cisco Catalyst 6800 Series Switches Denial of Service Vulnerability

Trust: 0.9

sources: CNVD: CNVD-2017-33008 // BID: 101040

DESCRIPTION

A vulnerability in the Virtual Private LAN Service (VPLS) code of Cisco IOS 15.0 through 15.4 for Cisco Catalyst 6800 Series Switches could allow an unauthenticated, adjacent attacker to cause a C6800-16P10G or C6800-16P10G-XL type line card to crash, resulting in a denial of service (DoS) condition. The vulnerability is due to a memory management issue in the affected software. An attacker could exploit this vulnerability by creating a large number of VPLS-generated MAC entries in the MAC address table of an affected device. A successful exploit could allow the attacker to cause a C6800-16P10G or C6800-16P10G-XL type line card to crash, resulting in a DoS condition. This vulnerability affects Cisco Catalyst 6800 Series Switches that are running a vulnerable release of Cisco IOS Software and have a Cisco C6800-16P10G or C6800-16P10G-XL line card in use with Supervisor Engine 6T. To be vulnerable, the device must also be configured with VPLS and the C6800-16P10G or C6800-16P10G-XL line card needs to be the core-facing MPLS interfaces. Cisco Bug IDs: CSCva61927. Cisco IOS Contains a resource management vulnerability. Vendors have confirmed this vulnerability Bug ID CSCva61927 It is released as.Service operation interruption (DoS) There is a possibility of being put into a state. IOS is one of the operating systems for network devices
