CVSS: 7.2EPSS: 0%CPEs: 171EXPL: 0CVE-2019-1795 – Cisco FXOS and NX-OS Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2019-1795
A vulnerability in the CLI of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker 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/108479 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-cmdinj-1795 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •

https://notcve.org/view.php?id=CVE-2019-1735
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local 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 certain CLI commands. 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 operating system with elevated privileges. An attacker would need valid user credentials to exploit this vulnerability. • http://www.securityfocus.com/bid/108365 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-cmdinj-1735 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •
CVSS: 8.6EPSS: 0%CPEs: 55EXPL: 0CVE-2019-1599 – Cisco NX-OS Software Netstack Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1599
A vulnerability in the network stack of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the affected device. The vulnerability is due to an issue with allocating and freeing memory buffers in the network stack. An attacker could exploit this vulnerability by sending crafted TCP streams to an affected device in a sustained way. A successful exploit could cause the network stack of an affected device to run out of available buffers, impairing operations of control plane and management plane protocols, resulting in a DoS condition. Note: This vulnerability can be triggered only by traffic that is destined to an affected device and cannot be exploited using traffic that transits an affected device. • http://www.securityfocus.com/bid/107342 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-netstack • CWE-399: Resource Management Errors CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.4EPSS: 0%CPEs: 31EXPL: 0CVE-2019-1594 – Cisco NX-OS Software 802.1X Extensible Authentication Protocol over LAN Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1594
A vulnerability in the 802.1X implementation for Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to incomplete input validation of Extensible Authentication Protocol over LAN (EAPOL) frames. An attacker could exploit this vulnerability by sending a crafted EAPOL frame to an interface on the targeted device. A successful exploit could allow the attacker to cause the Layer 2 (L2) forwarding process to restart multiple times, leading to a system-level restart of the device and a DoS condition. Note: This vulnerability affects only NX-OS devices configured with 802.1X functionality. • http://www.securityfocus.com/bid/107325 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nx-os-lan-auth • CWE-20: Improper Input Validation CWE-264: Permissions, Privileges, and Access Controls •
