https://notcve.org/view.php?id=CVE-2021-1431
A vulnerability in the vDaemon process of Cisco IOS XE SD-WAN Software could allow an unauthenticated, remote attacker to cause a device to reload, resulting a denial of service (DoS) condition. This vulnerability is due to insufficient handling of malformed packets. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en el proceso vDaemon del Software Cisco IOS XE SD-WAN, podría permitir a un atacante remoto no autenticado causar la recarga de un dispositivo, lo que resultará en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-sdwdos-4zeEeC9w • CWE-20: Improper Input Validation •
CVSS: 7.4EPSS: 0%CPEs: 37EXPL: 0CVE-2020-3409 – Cisco IOS and IOS XE Software PROFINET Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3409
A vulnerability in the PROFINET feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause an affected device to crash and reload, resulting in a denial of service (DoS) condition on the device. The vulnerability is due to insufficient processing logic for crafted PROFINET packets that are sent to an affected device. An attacker could exploit this vulnerability by sending crafted PROFINET packets to an affected device for processing. A successful exploit could allow the attacker to cause the device to crash and reload, resulting in a DoS condition on the device. Una vulnerabilidad en la funcionalidad PROFINET de Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante adyacente no autenticado causar que un dispositivo afectado se bloquee y recargue, resultando en una condición de denegación de servicio (DoS) en el dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-profinet-J9QMCHPB • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
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') •
