CVSS: 6.9EPSS: 0%CPEs: 5EXPL: 0CVE-2020-3416 – Cisco IOS XE Software for Cisco ASR 900 Series Route Switch Processor 3 Arbitrary Code Execution Vulnerabilities
https://notcve.org/view.php?id=CVE-2020-3416
Multiple vulnerabilities in the initialization routines that are executed during bootup of Cisco IOS XE Software for Cisco ASR 900 Series Aggregation Services Routers with a Route Switch Processor 3 (RSP3) installed could allow an authenticated, local attacker with high privileges to execute persistent code at bootup and break the chain of trust. These vulnerabilities are due to incorrect validations by boot scripts when specific ROM monitor (ROMMON) variables are set. An attacker could exploit these vulnerabilities by copying a specific file to the local file system of an affected device and defining specific ROMMON variables. A successful exploit could allow the attacker to run arbitrary code on the underlying operating system (OS) with root privileges. To exploit these vulnerabilities, an attacker would need to have 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-iosxe-rsp3-rce-jVHg8Z7c • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-749: Exposed Dangerous Method or Function •

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') •
CVSS: 8.6EPSS: 0%CPEs: 38EXPL: 0CVE-2020-3421 – Cisco IOS XE Software Zone-Based Firewall Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2020-3421
Multiple vulnerabilities in the Zone-Based Firewall feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the device to reload or stop forwarding traffic through the firewall. The vulnerabilities are due to incomplete handling of Layer 4 packets through the device. An attacker could exploit these vulnerabilities by sending a certain sequence of traffic patterns through the device. A successful exploit could allow the attacker to cause the device to reload or stop forwarding traffic through the firewall, resulting in a denial of service.

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: 7.4EPSS: 0%CPEs: 20EXPL: 0CVE-2020-3465 – Cisco IOS XE Software Ethernet Frame Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3465
A vulnerability in Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a device to reload. The vulnerability is due to incorrect handling of certain valid, but not typical, Ethernet frames. An attacker could exploit this vulnerability by sending the Ethernet frames onto the Ethernet segment. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en Cisco IOS XE Software, podría permitir a un atacante adyacente no autenticado causar la recarga de un dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-le-drTOB625 • CWE-20: Improper Input Validation •
