CVSS: 6.8EPSS: 0%CPEs: 15EXPL: 0CVE-2020-3223 – Cisco IOS XE Software Web UI Arbitrary File Read Vulnerability
https://notcve.org/view.php?id=CVE-2020-3223
A vulnerability in the web-based user interface (web UI) of Cisco IOS XE Software could allow an authenticated, remote attacker with administrative privileges to read arbitrary files on the underlying filesystem of the device. The vulnerability is due to insufficient file scope limiting. An attacker could exploit this vulnerability by creating a specific file reference on the filesystem and then accessing it through the web UI. An exploit could allow the attacker to read arbitrary files from the underlying operating system's filesystem. Una vulnerabilidad en la interfaz de usuario basada en web (IU web) de Cisco IOS XE Software, podría permitir a un atacante remoto autenticado con privilegios administrativos leer archivos arbitrarios en el sistema de archivos subyacente del dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webui-filerd-HngnDYGk • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
CVSS: 4.3EPSS: 0%CPEs: 22EXPL: 0CVE-2020-3222 – Cisco IOS XE Software Web UI Unauthenticated Proxy Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3222
A vulnerability in the web-based user interface (web UI) of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to bypass access control restrictions on an affected device. The vulnerability is due to the presence of a proxy service at a specific endpoint of the web UI. An attacker could exploit this vulnerability by connecting to the proxy service. An exploit could allow the attacker to bypass access restrictions on the network by proxying their access request through the management network of the affected device. As the proxy is reached over the management virtual routing and forwarding (VRF), this could reduce the effectiveness of the bypass. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webui-unauthprxy-KXXsbWh • CWE-17: DEPRECATED: Code •
CVSS: 8.6EPSS: 0%CPEs: 22EXPL: 0CVE-2020-3221 – Cisco IOS XE Software Flexible NetFlow Version 9 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3221
A vulnerability in the Flexible NetFlow Version 9 packet processor 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 on an affected device. The vulnerability is due to improper validation of parameters in a Flexible NetFlow Version 9 record. An attacker could exploit this vulnerability by sending a malformed Flexible NetFlow Version 9 packet to the Control and Provisioning of Wireless Access Points (CAPWAP) data port of an affected device. An exploit could allow the attacker to trigger an infinite loop, resulting in a process crash that would cause a reload of the device. Una vulnerabilidad en el procesador de paquetes Flexible NetFlow Versión 9 de Cisco IOS XE Software para los controladores inalámbricos Cisco Catalyst serie 9800, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-fnfv9-dos-HND6Fc9u • CWE-20: Improper Input Validation •
CVSS: 7.1EPSS: 0%CPEs: 68EXPL: 0CVE-2020-3220 – Cisco IOS XE Software IPsec VPN Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3220
A vulnerability in the hardware crypto driver of Cisco IOS XE Software for Cisco 4300 Series Integrated Services Routers and Cisco Catalyst 9800-L Wireless Controllers could allow an unauthenticated, remote attacker to disconnect legitimate IPsec VPN sessions to an affected device. The vulnerability is due to insufficient verification of authenticity of received Encapsulating Security Payload (ESP) packets. An attacker could exploit this vulnerability by tampering with ESP cleartext values as a man-in-the-middle. Una vulnerabilidad en el controlador criptográfico de hardware de Cisco IOS XE Software para Cisco 4300 Series Integrated Services Routers y Cisco Catalyst 9800-L Wireless Controllers, podría permitir a un atacante remoto no autenticado desconectar las sesiones legítimas de VPN IPsec en un dispositivo afectado. La vulnerabilidad es debido a una verificación insuficiente de la autenticidad de los paquetes de Encapsulating Security Payload (ESP) recibidos. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-vpn-dos-edOmW28Z • CWE-345: Insufficient Verification of Data Authenticity •

https://notcve.org/view.php?id=CVE-2020-3219
A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker to inject and execute arbitrary commands with administrative privileges on the underlying operating system of an affected device. The vulnerability is due to insufficient validation of user-supplied input to the web UI. An attacker could exploit this vulnerability by submitting crafted input to the web UI. A successful exploit could allow an attacker to execute arbitrary commands with administrative privileges on an affected device. Una vulnerabilidad en la Interfaz de Usuario web de Cisco IOS XE Software, podría permitir a un atacante remoto autenticado inyectar y ejecutar comandos arbitrarios con privilegios administrativos en el sistema operativo subyacente de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-web-cmdinj2-fOnjk2LD • CWE-20: Improper Input Validation CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
