VAR-201503-0177
Vulnerability from variot - Updated: 2023-12-18 12:38The DHCPv4 server in Cisco IOS XR 5.2.2 on ASR 9000 devices allows remote attackers to cause a denial of service (service outage) via a flood of crafted DHCP packets, aka Bug ID CSCup67822. Vendors have confirmed this vulnerability Bug ID CSCup67822 It is released as.A great deal of crafting by a third party DHCP Service disruption via packets ( Service stop ) There is a possibility of being in the state of. Cisco IOS XR is a member of the Cisco IOS Software family that uses a microkernel-based operating system architecture. Cisco ASR 9000 Series Aggregation Services Routers are prone to a remote denial-of-service vulnerability. Attackers can exploit this issue to cause the affected device to crash, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCup67822
