CVE-2019-1593 – Cisco NX-OS Software Bash Shell Role-Based Access Control Bypass Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1593
06 Mar 2019 — A vulnerability in the Bash shell implementation for Cisco NX-OS Software could allow an authenticated, local attacker to escalate their privilege level by executing commands authorized to other user roles. The attacker must authenticate with valid user credentials. The vulnerability is due to the incorrect implementation of a Bash shell command that allows role-based access control (RBAC) to be bypassed. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted com... • http://www.securityfocus.com/bid/107324 • CWE-264: Permissions, Privileges, and Access Controls •

CVE-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
06 Mar 2019 — 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 proc... • http://www.securityfocus.com/bid/107325 • CWE-20: Improper Input Validation CWE-264: Permissions, Privileges, and Access Controls •
