VAR-201309-0297
Vulnerability from variot - Updated: 2023-12-18 14:06The NTP implementation in Cisco IOS 12.0 through 12.4 and 15.0 through 15.1, and IOS XE 2.1 through 3.3, does not properly handle encapsulation of multicast NTP packets within MSDP SA messages, which allows remote attackers to cause a denial of service (device reload) by leveraging an MSDP peer relationship, aka Bug ID CSCuc81226. Vendors have confirmed this vulnerability Bug ID CSCuc81226 It is released as.By a third party MSDP Interfering with service operation by using peering relationship ( Device reload ) There is a possibility of being put into a state. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. A security vulnerability exists in the Cisco IOS IPv6 Network Time Protocol (ntp) that unauthenticated remote attackers can exploit vulnerabilities to suspend or reload devices. The vulnerability is that the affected device incorrectly processes the special multicast NTP packet. The remote attacker can use the vulnerability to send the special packet to reload the device, causing a denial of service attack. Cisco IOS is prone to a remote denial-of-service vulnerability. This issue is being tracked by Cisco Bug IDs CSCuc81226

"data": "The NTP implementation in Cisco IOS 12.0 through 12.4 and 15.0 through 15.1, and IOS XE 2.1 through 3.3, does not properly handle encapsulation of multicast NTP packets within MSDP SA messages, which allows remote attackers to cause a denial of service (device reload) by leveraging an MSDP peer relationship, aka Bug ID CSCuc81226. Vendors have confirmed this vulnerability Bug ID CSCuc81226 It is released as.By a third party MSDP Interfering with service operation by using peering relationship ( Device reload ) There is a possibility of being put into a state. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. A security vulnerability exists in the Cisco IOS IPv6 Network Time Protocol (ntp) that unauthenticated remote attackers can exploit vulnerabilities to suspend or reload devices. The vulnerability is that the affected device incorrectly processes the special multicast NTP packet. The remote attacker can use the vulnerability to send the special packet to reload the device, causing a denial of service attack. Cisco IOS is prone to a remote denial-of-service vulnerability. \nThis issue is being tracked by Cisco Bug IDs CSCuc81226",
