CVE-2019-1770 – Cisco NX-OS Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2019-1770
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker with administrator credentials to execute arbitrary commands on the underlying Linux operating system with the privilege level of root. The vulnerability is due to insufficient validation of arguments passed to a specific CLI command on the affected device. An attacker could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying Linux operating system with elevated privileges. An attacker would need valid administrator credentials to exploit this vulnerability. • http://www.securityfocus.com/bid/108376 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-cmdinj-1770 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-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 •
