Vulnerability from variot
A vulnerability in Cisco IOS XE Software running on Cisco cBR Series Converged Broadband Routers could allow an unauthenticated, adjacent attacker to cause high CPU usage on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to the incorrect handling of certain DHCP packets. An attacker could exploit this vulnerability by sending certain DHCP packets to a specific segment of an affected device. A successful exploit could allow the attacker to increase CPU usage on the affected device and cause a DoS condition. Cisco Bug IDs: CSCvg73687. Cisco IOS XE The software contains a resource management vulnerability. Vendors have confirmed this vulnerability Bug ID CSCvg73687 It is released as.Service operation interruption (DoS) There is a possibility of being put into a state. CiscocBRSeriesConvergedBroadbandRouters is a cBR series router device from Cisco. IOSXE is one of the operating systems dedicated to Cisco network devices. A resource management error vulnerability exists in IOSXE on CiscocBRSeriesConvergedBroadbandRouters that caused the program to fail to properly handle DHCP packets
