CVSS: 7.2EPSS: 0%CPEs: 65EXPL: 0CVE-2019-1767 – Cisco NX-OS Software Buffer Overflow and Command Injection Vulnerability
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 •
CVSS: 5.1EPSS: 0%CPEs: 81EXPL: 0CVE-2019-1731 – Cisco NX-OS Software SSH Key Information Disclosure Vulnerability
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 •
CVSS: 7.8EPSS: 0%CPEs: 22EXPL: 0CVE-2019-1803 – Cisco Nexus 9000 Series Fabric Switches Application Centric Infrastructure Mode Root Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1803
A vulnerability in the filesystem management for the Cisco Nexus 9000 Series Application Centric Infrastructure (ACI) Mode Switch Software could allow an authenticated, local attacker with administrator rights to gain elevated privileges as the root user on an affected device. The vulnerability is due to overly permissive file permissions of specific system files. An attacker could exploit this vulnerability by authenticating to an affected device, creating a crafted command string, and writing this crafted string to a specific file location. A successful exploit could allow the attacker to execute arbitrary operating system commands as root on an affected device. The attacker would need to have valid administrator credentials for the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-nexus9k-rpe • CWE-264: Permissions, Privileges, and Access Controls CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 6.5EPSS: 0%CPEs: 100EXPL: 0CVE-2019-1690 – Cisco Application Policy Infrastructure Controller IPv6 Link-Local Address Vulnerability
https://notcve.org/view.php?id=CVE-2019-1690
A vulnerability in the management interface of Cisco Application Policy Infrastructure Controller (APIC) software could allow an unauthenticated, adjacent attacker to gain unauthorized access on an affected device. The vulnerability is due to a lack of proper access control mechanisms for IPv6 link-local connectivity imposed on the management interface of an affected device. An attacker on the same physical network could exploit this vulnerability by attempting to connect to the IPv6 link-local address on the affected device. A successful exploit could allow the attacker to bypass default access control restrictions on an affected device. Cisco Application Policy Infrastructure Controller (APIC) devices running versions prior to 4.2(0.21c) are affected. • http://www.securityfocus.com/bid/107317 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-apic-ipv6 • CWE-284: Improper Access Control •
