| CVE-2021-27853 | 3 Cisco, Ieee, Ietf | 308 Catalyst 3650-12x48fd-e, Catalyst 3650-12x48fd-l, Catalyst 3650-12x48fd-s and 305 more | 2022-11-16 | 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-2022-20824 | 1 Cisco | 288 Mds 9506, Mds 9506 Firmware, Mds 9513 and 285 more | 2022-09-30 | N/A | 8.8 HIGH |
| A vulnerability in the Cisco Discovery Protocol feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper input validation of specific values that are within a Cisco Discovery Protocol message. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges or cause the Cisco Discovery Protocol process to crash and restart multiple times, which would cause the affected device to reload, resulting in a DoS condition. Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent). | |||||
| CVE-2022-20823 | 1 Cisco | 294 Nexus 3016, Nexus 3016 Firmware, Nexus 3016q and 291 more | 2022-09-01 | N/A | 8.6 HIGH |
| A vulnerability in the OSPF version 3 (OSPFv3) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to incomplete input validation of specific OSPFv3 packets. An attacker could exploit this vulnerability by sending a malicious OSPFv3 link-state advertisement (LSA) to an affected device. A successful exploit could allow the attacker to cause the OSPFv3 process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition. Note: The OSPFv3 feature is disabled by default. To exploit this vulnerability, an attacker must be able to establish a full OSPFv3 neighbor state with an affected device. For more information about exploitation conditions, see the Details section of this advisory. | |||||
| CVE-2019-1804 | 1 Cisco | 26 Nexus 93108tc-ex, Nexus 93108tc-ex Firmware, Nexus 93120tx and 23 more | 2021-11-03 | 10.0 HIGH | 9.8 CRITICAL |
| A vulnerability in the SSH key management for the Cisco Nexus 9000 Series Application Centric Infrastructure (ACI) Mode Switch Software could allow an unauthenticated, remote attacker to connect to the affected system with the privileges of the root user. The vulnerability is due to the presence of a default SSH key pair that is present in all devices. An attacker could exploit this vulnerability by opening an SSH connection via IPv6 to a targeted device using the extracted key materials. An exploit could allow the attacker to access the system with the privileges of the root user. This vulnerability is only exploitable over IPv6; IPv4 is not vulnerable. | |||||
