|---|---|---|---|---|---|
| CVE-2022-20870 | 1 Cisco | 193 Catalyst 3650, Catalyst 3650-12x48fd-e, Catalyst 3650-12x48fd-l and 190 more | 2024-02-28 | N/A | 8.6 HIGH |
| A vulnerability in the egress MPLS packet processing function of Cisco IOS XE Software for Cisco Catalyst 3650, Catalyst 3850, and Catalyst 9000 Family Switches could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to insufficient input validation of IPv4 traffic. An attacker could exploit this vulnerability by sending a malformed packet out of an affected MPLS-enabled interface. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. | |||||
| CVE-2021-27853 | 3 Cisco, Ieee, Ietf | 308 Catalyst 3650-12x48fd-e, Catalyst 3650-12x48fd-l, Catalyst 3650-12x48fd-s and 305 more | 2024-02-28 | N/A | 4.7 MEDIUM |
| Layer 2 network filtering capabilities such as IPv6 RA guard or ARP inspection can be bypassed using combinations of VLAN 0 headers and LLC/SNAP headers. | |||||
| CVE-2021-1620 | 1 Cisco | 277 1000 Integrated Services Router, 1100-4g\/6g Integrated Services Router, 1100-4p Integrated Services Router and 274 more | 2024-02-28 | 3.5 LOW | 7.7 HIGH |
| A vulnerability in the Internet Key Exchange Version 2 (IKEv2) support for the AutoReconnect feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to exhaust the free IP addresses from the assigned local pool. This vulnerability occurs because the code does not release the allocated IP address under certain failure conditions. An attacker could exploit this vulnerability by trying to connect to the device with a non-AnyConnect client. A successful exploit could allow the attacker to exhaust the IP addresses from the assigned local pool, which prevents users from logging in and leads to a denial of service (DoS) condition. | |||||
| CVE-2021-34703 | 1 Cisco | 203 1000 Integrated Services Router, 1100-4g\/6g Integrated Services Router, 1100-4p Integrated Services Router and 200 more | 2024-02-28 | 6.8 MEDIUM | 6.5 MEDIUM |
| A vulnerability in the Link Layer Discovery Protocol (LLDP) message parser of Cisco IOS Software and Cisco IOS XE Software could allow an attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. This vulnerability is due to improper initialization of a buffer. An attacker could exploit this vulnerability via any of the following methods: An authenticated, remote attacker could access the LLDP neighbor table via either the CLI or SNMP while the device is in a specific state. An unauthenticated, adjacent attacker could corrupt the LLDP neighbor table by injecting specific LLDP frames into the network and then waiting for an administrator of the device or a network management system (NMS) managing the device to retrieve the LLDP neighbor table of the device via either the CLI or SNMP. An authenticated, adjacent attacker with SNMP read-only credentials or low privileges on the device CLI could corrupt the LLDP neighbor table by injecting specific LLDP frames into the network and then accessing the LLDP neighbor table via either the CLI or SNMP. A successful exploit could allow the attacker to cause the affected device to crash, resulting in a reload of the device. | |||||
| CVE-2020-3508 | 1 Cisco | 141 1000v, 1100-4g Integrated Services Router, 1100-4gltegb Integrated Services Router and 138 more | 2024-02-28 | 6.1 MEDIUM | 7.4 HIGH |
| A vulnerability in the IP Address Resolution Protocol (ARP) feature of Cisco IOS XE Software for Cisco ASR 1000 Series Aggregation Services Routers with a 20-Gbps Embedded Services Processor (ESP) installed could allow an unauthenticated, adjacent attacker to cause an affected device to reload, resulting in a denial of service condition. The vulnerability is due to insufficient error handling when an affected device has reached platform limitations. An attacker could exploit this vulnerability by sending a malicious series of IP ARP messages to an affected device. A successful exploit could allow the attacker to exhaust system resources, which would eventually cause the affected device to reload. | |||||
