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 •
CVSS: 7.7EPSS: 0%CPEs: 1198EXPL: 0CVE-2020-3200 – Cisco IOS and IOS XE Software Secure Shell Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3200
A vulnerability in the Secure Shell (SSH) server code of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to cause an affected device to reload. The vulnerability is due to an internal state not being represented correctly in the SSH state machine, which leads to an unexpected behavior. An attacker could exploit this vulnerability by creating an SSH connection to an affected device and using a specific traffic pattern that causes an error condition within that connection. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en el código del servidor Secure Shell (SSH) de Cisco IOS Software y el Cisco IOS XE Software, podría permitir a un atacante remoto autenticado causar una recarga de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ssh-dos-Un22sd2A • CWE-371: State Issues CWE-436: Interpretation Conflict •
CVSS: 8.6EPSS: 0%CPEs: 490EXPL: 0CVE-2020-3228 – Cisco IOS, IOS XE, and NX-OS Software Security Group Tag Exchange Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3228
A vulnerability in Security Group Tag Exchange Protocol (SXP) in Cisco IOS Software, Cisco IOS XE Software, and Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability exists because crafted SXP packets are mishandled. An attacker could exploit this vulnerability by sending specifically crafted SXP packets to the affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Una vulnerabilidad en Security Group Tag Exchange Protocol (SXP) en Cisco IOS Software, Cisco IOS XE Software y Cisco NX-OS Software, podría permitir a un atacante remoto no autenticado causar que el dispositivo afectado se vuelva a cargar, resultando en una condición denegación de servicio (DoS ). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sxp-68TEVzR • CWE-20: Improper Input Validation •
CVSS: 7.5EPSS: 0%CPEs: 792EXPL: 0CVE-2020-3230 – Cisco IOS and IOS XE Software Internet Key Exchange Version 2 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3230
A vulnerability in the Internet Key Exchange Version 2 (IKEv2) implementation in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to prevent IKEv2 from establishing new security associations. The vulnerability is due to incorrect handling of crafted IKEv2 SA-Init packets. An attacker could exploit this vulnerability by sending crafted IKEv2 SA-Init packets to the affected device. An exploit could allow the attacker to cause the affected device to reach the maximum incoming negotiation limits and prevent further IKEv2 security associations from being formed. Una vulnerabilidad en la implementación de Internet Key Exchange Versión 2 (IKEv2) en Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante remoto no autenticado impedir que IKEv2 establezca nuevas asociaciones de seguridad. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ikev2-9p23Jj2a • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2020-3229
A vulnerability in Role Based Access Control (RBAC) functionality of Cisco IOS XE Web Management Software could allow a Read-Only authenticated, remote attacker to execute commands or configuration changes as an Admin user. The vulnerability is due to incorrect handling of RBAC for the administration GUI. An attacker could exploit this vulnerability by sending a modified HTTP request to the affected device. An exploit could allow the attacker as a Read-Only user to execute CLI commands or configuration changes as if they were an Admin user. Una vulnerabilidad en la funcionalidad Role Based Access Control (RBAC) de Cisco IOS XE Web Management Software, podría permitir a un atacante remoto autenticado Read-Only ejecutar comandos o cambios de configuración como usuario administrador. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webui-PZgQxjfG • CWE-264: Permissions, Privileges, and Access Controls CWE-863: Incorrect Authorization •
