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 •

https://notcve.org/view.php?id=CVE-2019-1589
A vulnerability in the Trusted Platform Module (TPM) functionality of software for Cisco Nexus 9000 Series Fabric Switches in Application Centric Infrastructure (ACI) mode could allow an unauthenticated, local attacker with physical access to view sensitive information on an affected device. The vulnerability is due to a lack of proper data-protection mechanisms for disk encryption keys that are used within the partitions on an affected device hard drive. An attacker could exploit this vulnerability by obtaining physical access to the affected device to view certain cleartext keys. A successful exploit could allow the attacker to execute a custom boot process or conduct further attacks on an affected device.

https://notcve.org/view.php?id=CVE-2019-1590
A vulnerability in the Transport Layer Security (TLS) certificate validation functionality of Cisco Nexus 9000 Series Application Centric Infrastructure (ACI) Mode Switch Software could allow an unauthenticated, remote attacker to perform insecure TLS client authentication on an affected device. The vulnerability is due to insufficient TLS client certificate validations for certificates sent between the various components of an ACI fabric. An attacker who has possession of a certificate that is trusted by the Cisco Manufacturing CA and the corresponding private key could exploit this vulnerability by presenting a valid certificate while attempting to connect to the targeted device. An exploit could allow the attacker to gain full control of all other components within the ACI fabric of an affected device. Una vulnerabilidad en la funcionalidad de validación de certificados de Transport Layer Security (TLS) del software Nexus 9000 Series Switch de Cisco en modo Application Centric Infrastructure (ACI), podría permitir a un atacante remoto no autenticado realizar una autenticación no segura del cliente TLS en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-aci-insecure-fabric • CWE-295: Improper Certificate Validation •

https://notcve.org/view.php?id=CVE-2019-1592
A vulnerability in the background operations functionality of Cisco Nexus 9000 Series Application Centric Infrastructure (ACI) Mode Switch Software could allow an authenticated, local attacker to gain elevated privileges as root on an affected device. The vulnerability is due to insufficient validation of user-supplied files on an affected device. An attacker could exploit this vulnerability by logging in to the CLI of the affected device and creating a crafted file in a specific directory on the filesystem. A successful exploit could allow the attacker to execute arbitrary operating system commands as root on an affected device.

https://notcve.org/view.php?id=CVE-2019-1587
A vulnerability in Cisco Nexus 9000 Series Fabric Switches in Application Centric Infrastructure (ACI) mode could allow an authenticated, remote attacker to access sensitive information. The vulnerability occurs because the affected software does not properly validate user-supplied input. An attacker could exploit this vulnerability by issuing certain commands with filtered query results on the device. This action may cause returned messages to display confidential system information. A successful exploit could allow the attacker to read sensitive information on the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-aci-filter-query • CWE-20: Improper Input Validation CWE-399: Resource Management Errors •
