CVSS: 7.2EPSS: 0%CPEs: 70EXPL: 0CVE-2019-1769 – Cisco NX-OS Software Line Card Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2019-1769
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 of an attached line card 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 of an attached line card with elevated privileges. An attacker would need valid administrator credentials to exploit this vulnerability. • http://www.securityfocus.com/bid/108393 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-linecardinj-1769 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

https://notcve.org/view.php?id=CVE-2019-1767
A vulnerability in the implementation of a specific CLI command for Cisco NX-OS Software could allow an authenticated, local attacker with administrator credentials to cause a buffer overflow condition or perform command injection. This could allow the attacker to execute arbitrary commands with elevated privileges on the underlying operating system of an affected device. The vulnerability is due to insufficient validation of arguments passed to a certain CLI command. An attacker could exploit this vulnerability by including malicious input as the argument of the affected CLI command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with root privileges. • http://www.securityfocus.com/bid/108386 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-overflow-inj • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.2EPSS: 0%CPEs: 51EXPL: 0CVE-2019-1730 – Cisco NX-OS Software Bash Bypass Guest Shell Vulnerability
https://notcve.org/view.php?id=CVE-2019-1730
A vulnerability in the Bash shell implementation for Cisco NX-OS Software could allow an authenticated, local attacker to bypass the limited command set of the restricted Guest Shell and execute commands at the privilege level of a network-admin user outside of the Guest Shell. The attacker must authenticate with valid administrator device credentials. The vulnerability is due to the incorrect implementation of a CLI command that allows a Bash command to be incorrectly invoked on the Guest Shell CLI. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the Guest Shell prompt. A successful exploit could allow the attacker to issue commands that should be restricted by a Guest Shell account. na vulnerabilidad en la implementación Bash Shell para el software NX-OS de Cisco, podría permitir a un atacante local autentificado omitir el conjunto de comandos limitados del Guest Shell y ejecutar comandos en el nivel de privilegio de un usuario administrador de la red fuera del Guest Shell. • http://www.securityfocus.com/bid/108397 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-bash-bypass • CWE-264: Permissions, Privileges, and Access Controls •

https://notcve.org/view.php?id=CVE-2019-1731
A vulnerability in the SSH CLI key management functionality of Cisco NX-OS Software could allow an authenticated, local attacker to expose a user's private SSH key to all authenticated users on the targeted device. The attacker must authenticate with valid administrator device credentials. The vulnerability is due to incomplete error handling if a specific error type occurs during the SSH key export. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the CLI. A successful exploit could allow the attacker to expose a user's private SSH key. • http://www.securityfocus.com/bid/108353 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-ssh-info • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-755: Improper Handling of Exceptional Conditions •
