https://notcve.org/view.php?id=CVE-2021-1583
A vulnerability in the fabric infrastructure file system access control of Cisco Nexus 9000 Series Fabric Switches in Application Centric Infrastructure (ACI) mode could allow an authenticated, local attacker to read arbitrary files on an affected system. This vulnerability is due to improper access control. An attacker with Administrator privileges could exploit this vulnerability by executing a specific vulnerable command on an affected device. A successful exploit could allow the attacker to read arbitrary files on the file system of the affected device. Una vulnerabilidad en el control de acceso al sistema de archivos de la infraestructura de fábrica de Cisco Nexus 9000 Series Fabric Switches en el modo Application Centric Infrastructure (ACI) podría permitir a un atacante local autenticado leer archivos arbitrarios en un sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-naci-afr-UtjfO2D7 • CWE-284: Improper Access Control •
CVSS: 8.6EPSS: 0%CPEs: 470EXPL: 0CVE-2021-1387 – Cisco NX-OS Software IPv6 Netstack Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1387
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 an affected device. This vulnerability exists because the software improperly releases resources when it processes certain IPv6 packets that are destined to an affected device. An attacker could exploit this vulnerability by sending multiple crafted IPv6 packets to an affected device. A successful exploit could cause the network stack to run out of available buffers, impairing operations of control plane and management plane protocols and resulting in a DoS condition. Manual intervention would be required to restore normal operations on the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-ipv6-netstack-edXPGV7K • CWE-401: Missing Release of Memory after Effective Lifetime •
