CVSS: 8.6EPSS: 0%CPEs: 30EXPL: 0CVE-2020-3422 – Cisco IOS XE Software IP Service Level Agreements Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3422
A vulnerability in the IP Service Level Agreement (SLA) responder feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the IP SLA responder to reuse an existing port, resulting in a denial of service (DoS) condition. The vulnerability exists because the IP SLA responder could consume a port that could be used by another feature. An attacker could exploit this vulnerability by sending specific IP SLA control packets to the IP SLA responder on an affected device. The control packets must include the port number that could be used by another configured feature. A successful exploit could allow the attacker to cause an in-use port to be consumed by the IP SLA responder, impacting the feature that was using the port and resulting in a DoS condition. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipsla-jw2DJmSv • CWE-371: State Issues •

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: 8EXPL: 0CVE-2020-3429 – Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family WPA Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3429
A vulnerability in the WPA2 and WPA3 security implementation of Cisco IOS XE Wireless Controller Software for the Cisco Catalyst 9000 Family could allow an unauthenticated, adjacent attacker to cause denial of service (DoS) condition on an affected device. The vulnerability is due to incorrect packet processing during the WPA2 and WPA3 authentication handshake when configured for dot1x or pre-shared key (PSK) authentication key management (AKM) with 802.11r BSS Fast Transition (FT) enabled. An attacker could exploit this vulnerability by sending a crafted authentication packet to an affected device. A successful exploit could cause an affected device to reload, resulting in a DoS condition. Una vulnerabilidad en la implementación de seguridad WPA2 y WPA3 de Cisco IOS XE Wireless Controller Software para Cisco Catalyst 9000 Family, podría permitir a un atacante adyacente no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wpa-dos-cXshjerc • 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 •
CVSS: 7.4EPSS: 0%CPEs: 7EXPL: 0CVE-2020-3488 – Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family CAPWAP Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2020-3488
Multiple vulnerabilities in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition of an affected device. These vulnerabilities are due to insufficient validation of CAPWAP packets. An attacker could exploit these vulnerabilities by sending a malformed CAPWAP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition on the affected device. Múltiples vulnerabilidades en el procesamiento del protocolo de Control and Provisioning of Wireless Access Points (CAPWAP) de Cisco IOS XE Software para Cisco Catalyst 9800 Series Wireless Controllers, podrían permitir a un atacante adyacente no autenticado causar una condición de denegación de servicio (DoS) de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-capwap-dos-TPdNTdyq • CWE-20: Improper Input Validation •
