CVSS: 8.6EPSS: 0%CPEs: 13EXPL: 0CVE-2018-0378 – Cisco NX-OS Software for Nexus 5500, 5600, and 6000 Series Switches Precision Time Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0378
A vulnerability in the Precision Time Protocol (PTP) feature of Cisco Nexus 5500, 5600, and 6000 Series Switches running Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of protection against PTP frame flood attacks. An attacker could exploit this vulnerability by sending large streams of malicious IPv4 or IPv6 PTP traffic to the affected device. A successful exploit could allow the attacker to cause a DoS condition, impacting the traffic passing through the device. Una vulnerabilidad en la característica Precision Time Protocol (PTP) de Cisco Nexus 5500, 5600 y 6000 Series Switches que ejecutan Cisco NX-OS Software podría permitir que un atacante remoto no autenticado cree una condición de denegación de servicio (DoS) en un dispositivo afectado. • http://www.securityfocus.com/bid/105669 http://www.securitytracker.com/id/1041920 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181017-nexus-ptp-dos • CWE-20: Improper Input Validation •
CVSS: 7.7EPSS: 0%CPEs: 1EXPL: 0CVE-2018-0456 – Cisco NX-OS Software Authenticated Simple Network Management Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0456
A vulnerability in the Simple Network Management Protocol (SNMP) input packet processor of Cisco NX-OS Software could allow an authenticated, remote attacker to cause the SNMP application of an affected device to restart unexpectedly. The vulnerability is due to improper validation of SNMP protocol data units (PDUs) in SNMP packets. An attacker could exploit this vulnerability by sending a crafted SNMP packet to an affected device. A successful exploit could allow the attacker to cause the SNMP application to restart multiple times, leading to a system-level restart and a denial of service (DoS) condition. Una vulnerabilidad en el procesador de paquetes entrantes SNMP (Simple Network Management Protocol) del software Cisco NX-OS podría permitir que la aplicación SNMP se reinicie inesperadamente en un dispositivo afectado. • http://www.securityfocus.com/bid/105668 http://www.securitytracker.com/id/1041921 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181017-nxos-snmp • CWE-20: Improper Input Validation •
CVSS: 8.8EPSS: 0%CPEs: 17EXPL: 0CVE-2018-0395 – Cisco FXOS and NX-OS Software Link Layer Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0395
A vulnerability in the Link Layer Discovery Protocol (LLDP) implementation for Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition when the device unexpectedly reloads. The vulnerability is due to improper input validation of certain type, length, value (TLV) fields of the LLDP frame header. An attacker could exploit this vulnerability by sending a crafted LLDP packet to an interface on the targeted device. A successful exploit could allow the attacker to cause the switch to reload unexpectedly. Una vulnerabilidad en la implementación LLDP (Link Layer Discovery Protocol) para Cisco FXOS Software y Cisco NX-OS Software podría permitir que un atacante adyacente no autenticado cree una condición de denegación de servicio (DoS) cuando el dispositivo se recarga inesperadamente. • http://www.securityfocus.com/bid/105674 http://www.securitytracker.com/id/1041919 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181017-fxnx-os-dos • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2018-0372
A vulnerability in the DHCPv6 feature of the Cisco Nexus 9000 Series Fabric Switches in Application-Centric Infrastructure (ACI) Mode could allow an unauthenticated, remote attacker to cause the device to run low on system memory, which could result in a Denial of Service (DoS) condition on an affected system. The vulnerability is due to improper memory management when DHCPv6 packets are received on an interface of the targeted device. An attacker could exploit this vulnerability by sending a high number of malicious DHCPv6 packets to be processed by an affected device. A successful exploit could allow the attacker to cause the system to run low on memory, which could cause an eventual reboot of an affected device. The vulnerability only applies to IPv6 protocol packets and not for IPv4 protocol packets. • http://www.securitytracker.com/id/1041348 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-20180718-nexus-9000-dos • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2018-0306
A vulnerability in the CLI parser of Cisco NX-OS Software could allow an authenticated, local attacker to perform a command-injection attack on an affected device. The vulnerability is due to insufficient input validation of command arguments. An attacker could exploit this vulnerability by injecting malicious command arguments into a vulnerable CLI command. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the affected device. Note: This vulnerability requires that any feature license is uploaded to the device. • http://www.securitytracker.com/id/1041169 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180620-nx-os-cli-execution • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
