CVE-2021-34770 – Cisco IOS XE Software for Catalyst 9000 Family Wireless Controllers CAPWAP Remote Code Execution Vulnerability

https://notcve.org/view.php?id=CVE-2021-34770

A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9000 Family Wireless Controllers could allow an unauthenticated, remote attacker to execute arbitrary code with administrative privileges or cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a logic error that occurs during the validation of CAPWAP packets. An attacker could exploit this vulnerability by sending a crafted CAPWAP packet to an affected device. A successful exploit could allow the attacker to execute arbitrary code with administrative privileges or cause the affected device to crash and reload, resulting in a DoS condition. Una vulnerabilidad en el procesamiento del protocolo Control and Provisioning of Wireless Access Points (CAPWAP) de Cisco IOS XE Software para Cisco Catalyst 9000 Family Wireless Controllers podría permitir a un atacante remoto no autenticado ejecutar código arbitrario con privilegios administrativos o causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ewlc-capwap-rce-LYgj8Kf • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

CVE-2021-34769 – Cisco IOS XE Software for Catalyst 9000 Family Wireless Controllers CAPWAP Denial of Service Vulnerabilities

https://notcve.org/view.php?id=CVE-2021-34769

Multiple vulnerabilities in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9000 Family Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to insufficient validation of CAPWAP packets. An attacker could exploit the 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.

CVE-2021-34767 – Cisco IOS XE Software for Catalyst 9800 Series Wireless Controllers IPv6 Denial of Service Vulnerability

https://notcve.org/view.php?id=CVE-2021-34767

A vulnerability in IPv6 traffic processing of Cisco IOS XE Wireless Controller Software for Cisco Catalyst 9000 Family Wireless Controllers could allow an unauthenticated, adjacent attacker to cause a Layer 2 (L2) loop in a configured VLAN, resulting in a denial of service (DoS) condition for that VLAN. The vulnerability is due to a logic error when processing specific link-local IPv6 traffic. An attacker could exploit this vulnerability by sending a crafted IPv6 packet that would flow inbound through the wired interface of an affected device. A successful exploit could allow the attacker to cause traffic drops in the affected VLAN, thus triggering the DoS condition. Una vulnerabilidad en el procesamiento del tráfico IPv6 de Cisco IOS XE Wireless Controller Software para Cisco Catalyst 9000 Family Wireless Controllers podría permitir a un atacante adyacente no autenticado causar un bucle de capa 2 (L2) en una VLAN configurada, resultando en una condición de denegación de servicio (DoS) para esa VLAN. • https://github.com/lukejenkins/CVE-2021-34767 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ewlc-ipv6-dos-NMYeCnZv • CWE-670: Always-Incorrect Control Flow Implementation •
