CVSS: 7.2EPSS: 0%CPEs: 98EXPL: 0CVE-2020-3417 – Cisco IOS XE Software Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-3417
A vulnerability in Cisco IOS XE Software could allow an authenticated, local attacker to execute persistent code at boot time and break the chain of trust. This vulnerability is due to incorrect validations by boot scripts when specific ROM monitor (ROMMON) variables are set. An attacker could exploit this vulnerability by installing code to a specific directory in the underlying operating system (OS) and setting a specific ROMMON variable. A successful exploit could allow the attacker to execute persistent code on the underlying OS. To exploit this vulnerability, the attacker would need access to the root shell on the device or have physical access to the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xbace-OnCEbyS • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

https://notcve.org/view.php?id=CVE-2020-3425
Multiple vulnerabilities in the web management framework of Cisco IOS XE Software could allow an authenticated, remote attacker with read-only privileges to elevate privileges to the level of an Administrator user on an affected device. For more information about these vulnerabilities, see the Details section of this advisory. Múltiples vulnerabilidades en el framework de administración web de Cisco IOS XE Software, podrían permitir a un atacante remoto autenticado con privilegios de solo lectura elevar los privilegios al nivel de un usuario administrador en un dispositivo afectado. Para más información sobre estas vulnerabilidades, consulte la sección Detalles de este aviso. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-webui-priv-esc-K8zvEWM • CWE-20: Improper Input Validation •
CVSS: 7.7EPSS: 0%CPEs: 58EXPL: 0CVE-2020-3232 – Cisco ASR 920 Series Aggregation Services Router Model 12SZ-IM SNMP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3232
A vulnerability in the Simple Network Management Protocol (SNMP) implementation in Cisco ASR 920 Series Aggregation Services Router model ASR920-12SZ-IM could allow an authenticated, remote attacker to cause the device to reload. The vulnerability is due to incorrect handling of data that is returned for Cisco Discovery Protocol queries to SNMP. An attacker could exploit this vulnerability by sending a request for Cisco Discovery Protocol information by using SNMP. An exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en la implementación de Simple Network Management Protocol (SNMP) en Cisco ASR 920 Series Aggregation Services Router modelo ASR920-12SZ-IM, podría permitir a un atacante remoto autenticado causar que el dispositivo se vuelva a cargar. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asr920-ABjcLmef • CWE-19: Data Processing Errors •
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: 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 •
