CVSS: 7.8EPSS: 0%CPEs: 128EXPL: 0CVE-2020-3404 – Cisco IOS XE Software Consent Token Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3404
A vulnerability in the persistent Telnet/Secure Shell (SSH) CLI of Cisco IOS XE Software could allow an authenticated, local attacker to gain shell access on an affected device and execute commands on the underlying operating system (OS) with root privileges. The vulnerability is due to insufficient enforcement of the consent token in authorizing shell access. An attacker could exploit this vulnerability by authenticating to the persistent Telnet/SSH CLI on an affected device and requesting shell access. A successful exploit could allow the attacker to gain shell access on the affected device and execute commands on the underlying OS with root privileges. Una vulnerabilidad en la CLI Telnet/Secure Shell (SSH) persistente de Cisco IOS XE Software, podría permitir a un atacante local autenticado obtener acceso de shell en un dispositivo afectado y ejecutar comandos en el sistema operativo (SO) subyacente con privilegios root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-ctbypass-7QHAfHkK • CWE-863: Incorrect Authorization •
CVSS: 8.6EPSS: 0%CPEs: 128EXPL: 0CVE-2020-3407 – Cisco IOS XE Software RESTCONF and NETCONF-YANG Access Control List Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3407
A vulnerability in the RESTCONF and NETCONF-YANG access control list (ACL) function of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the device to reload. The vulnerability is due to incorrect processing of the ACL that is tied to the RESTCONF or NETCONF-YANG feature. An attacker could exploit this vulnerability by accessing the device using RESTCONF or NETCONF-YANG. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en la función de lista de control de acceso (ACL) de RESTCONF y NETCONF-YANG de Cisco IOS XE Software, podría permitir a un atacante remoto no autenticado causar que el dispositivo se recargue. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-confacl-HbPtfSuO • CWE-476: NULL Pointer Dereference •
CVSS: 8.6EPSS: 0%CPEs: 129EXPL: 0CVE-2020-3408 – Cisco IOS and IOS XE Software Split DNS Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3408
A vulnerability in the Split DNS 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 vulnerability occurs because the regular expression (regex) engine that is used with the Split DNS feature of affected releases may time out when it processes the DNS name list configuration. An attacker could exploit this vulnerability by trying to resolve an address or hostname that the affected device handles. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en la funcionalidad Split DNS de Cisco IOS Software y Cisco IOS XE Software, podría 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-splitdns-SPWqpdGW • CWE-185: Incorrect Regular Expression CWE-400: Uncontrolled Resource Consumption •
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 •

https://notcve.org/view.php?id=CVE-2020-3414
A vulnerability in the packet processing of Cisco IOS XE Software for Cisco 4461 Integrated Services Routers could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to incorrect processing of IPv4 or IPv6 traffic to or through an affected device. An attacker could exploit this vulnerability by sending IP traffic to or through 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 procesamiento de paquetes de Cisco IOS XE Software para Cisco 4461 Integrated Services Routers, podría 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-ISR4461-gKKUROhx • CWE-19: Data Processing Errors CWE-400: Uncontrolled Resource Consumption •
