CVSS: 10.0EPSS: 0%CPEs: 70EXPL: 0CVE-2020-3227 – Cisco IOx for IOS XE Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3227
A vulnerability in the authorization controls for the Cisco IOx application hosting infrastructure in Cisco IOS XE Software could allow an unauthenticated, remote attacker to execute Cisco IOx API commands without proper authorization. The vulnerability is due to incorrect handling of requests for authorization tokens. An attacker could exploit this vulnerability by using a crafted API call to request such a token. An exploit could allow the attacker to obtain an authorization token and execute any of the IOx API commands on an affected device. Una vulnerabilidad en los controles de autorización para la infraestructura de alojamiento de la aplicación Cisco IOx en Cisco IOS XE Software, podría permitir a un atacante remoto no autenticado ejecutar comandos de Cisco IOx API sin la autorización apropiada. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ioxPE-KgGvCAf9 • CWE-264: Permissions, Privileges, and Access Controls CWE-863: Incorrect Authorization •
CVSS: 8.6EPSS: 0%CPEs: 260EXPL: 0CVE-2020-3226 – Cisco IOS and IOS XE Software Session Initiation Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3226
A vulnerability in the Session Initiation Protocol (SIP) library of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient sanity checks on received SIP messages. An attacker could exploit this vulnerability by sending crafted SIP messages to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service condition. Una vulnerabilidad en la biblioteca Session Initiation Protocol (SIP) de Cisco IOS Software y Cisco IOS XE Software, podría permitir que un atacante remoto no autenticado desencadene una recarga de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sip-Cv28sQw2 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2020-3225
Multiple vulnerabilities in the implementation of the Common Industrial Protocol (CIP) feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerabilities are due to insufficient input processing of CIP traffic. An attacker could exploit these vulnerabilities by sending crafted CIP traffic to be processed by an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Múltiples vulnerabilidades en la implementación de la funcionalidad Common Industrial Protocol (CIP) de Cisco IOS Software y Cisco IOS XE Software, podrían permitir a un atacante remoto no autenticado causar la recarga de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cipdos-hkfTZXEx • CWE-20: Improper Input Validation •
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: 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 •
