CVSS: 8.6EPSS: 0%CPEs: 15EXPL: 0CVE-2020-3359 – Cisco IOS XE Software for Catalyst 9800 Series Wireless Controllers Multicast DNS Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3359
A vulnerability in the multicast DNS (mDNS) feature of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to improper validation of mDNS packets. An attacker could exploit this vulnerability by sending a crafted mDNS packet to an affected device. A successful exploit could cause a device to reload, resulting in a DoS condition. Una vulnerabilidad en la función multicast DNS (mDNS) de Cisco IOS XE Software para Cisco Catalyst 9800 Series Wireless Controllers, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-mdns-dos-3tH6cA9J • CWE-20: Improper Input Validation •
CVSS: 7.4EPSS: 0%CPEs: 7EXPL: 0CVE-2020-3390 – Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family SNMP Trap Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3390
A vulnerability in Simple Network Management Protocol (SNMP) trap generation for wireless clients of the Cisco IOS XE Wireless Controller Software for the Cisco Catalyst 9000 Family could allow an unauthenticated, adjacent attacker to cause the device to unexpectedly reload, causing a denial of service (DoS) condition on an affected device. The vulnerability is due to the lack of input validation of the information used to generate an SNMP trap in relation to a wireless client connection. An attacker could exploit this vulnerability by sending an 802.1x packet with crafted parameters during the wireless authentication setup phase of a connection. A successful exploit could allow the attacker to cause the device to reload, causing a DoS condition. Una vulnerabilidad en la generación de trampas Simple Network Management Protocol (SNMP) para clientes inalámbricos del Cisco IOS XE Wireless Controller Software para la Cisco Catalyst 9000 Family, podría permitir a un atacante adyacente no autenticado causar que el dispositivo se recargue inesperadamente, provocando una denegación de servicio ( DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-ewlc-snmp-dos-wNkedg9K • CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 128EXPL: 0CVE-2020-3393 – Cisco IOS XE Software IOx Application Hosting Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3393
A vulnerability in the application-hosting subsystem of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to root on an affected device. The attacker could execute IOS XE commands outside the application-hosting subsystem Docker container as well as on the underlying Linux operating system. These commands could be run as the root user. The vulnerability is due to a combination of two factors: (a) incomplete input validation of the user payload of CLI commands, and (b) improper role-based access control (RBAC) when commands are issued at the command line within the application-hosting subsystem. An attacker could exploit this vulnerability by using a CLI command with crafted user input. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-iox-app-host-mcZcnsBt • CWE-20: Improper Input Validation CWE-269: Improper Privilege Management •
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: 8.6EPSS: 0%CPEs: 9EXPL: 0CVE-2020-3399 – Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family CAPWAP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3399
A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition of an affected device. The vulnerability is due to insufficient input validation during CAPWAP packet processing. An attacker could exploit this vulnerability by sending a crafted CAPWAP packet to an affected device, resulting in a buffer over-read. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition on the affected device. Una vulnerabilidad en el procesamiento del protocolo Control and Provisioning of Wireless Access Points (CAPWAP) de Cisco IOS XE Software para Cisco Catalyst 9800 Series Wireless Controllers Series, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-capwap-dos-ShFzXf • CWE-125: Out-of-bounds Read CWE-126: Buffer Over-read •
