CVSS: 7.2EPSS: 0%CPEs: 56EXPL: 0CVE-2020-3396 – Cisco IOS XE Software IOx Guest Shell USB SSD Namespace Protection Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3396
A vulnerability in the file system on the pluggable USB 3.0 Solid State Drive (SSD) for Cisco IOS XE Software could allow an authenticated, physical attacker to remove the USB 3.0 SSD and modify sensitive areas of the file system, including the namespace container protections. The vulnerability occurs because the USB 3.0 SSD control data is not stored on the internal boot flash. An attacker could exploit this vulnerability by removing the USB 3.0 SSD, modifying or deleting files on the USB 3.0 SSD by using another device, and then reinserting the USB 3.0 SSD on the original device. A successful exploit could allow the attacker to remove container protections and perform file actions outside the namespace of the container with root privileges. Una vulnerabilidad en el sistema de archivos en la USB 3.0 Solid State Drive (SSD) conectable para el Cisco IOS XE Software, podría permitir a un atacante físico autenticado eliminar el SSD USB 3.0 y modificar áreas sensibles del sistema de archivos, incluyendo las protecciones del contenedor de espacio de nombres. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iox-usb-guestshell-WmevScDj • CWE-269: Improper Privilege Management CWE-284: Improper Access Control •
CVSS: 7.4EPSS: 0%CPEs: 149EXPL: 0CVE-2020-3508 – Cisco IOS XE Software for Cisco ASR 1000 Series 20-Gbps Embedded Services Processor IP ARP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3508
A vulnerability in the IP Address Resolution Protocol (ARP) feature of Cisco IOS XE Software for Cisco ASR 1000 Series Aggregation Services Routers with a 20-Gbps Embedded Services Processor (ESP) installed could allow an unauthenticated, adjacent attacker to cause an affected device to reload, resulting in a denial of service condition. The vulnerability is due to insufficient error handling when an affected device has reached platform limitations. An attacker could exploit this vulnerability by sending a malicious series of IP ARP messages to an affected device. A successful exploit could allow the attacker to exhaust system resources, which would eventually cause the affected device to reload. Una vulnerabilidad en la funcionalidad de Address Resolution Protocol (ARP) de IP de Cisco IOS XE Software para Cisco ASR 1000 Series Aggregation Services Routers con un Embedded Services Processor (ESP) de 20-Gbps instalado, podría permitir a un atacante adyacente no autenticado causar la recarga de un dispositivo afectado, resultando en una condición de denegación de servicio. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esp20-arp-dos-GvHVggqJ • CWE-400: Uncontrolled Resource Consumption •
