A vulnerability in the file system permissions of Cisco IOS XE Software could allow an authenticated, local attacker to obtain read and write access to critical configuration or system files. The vulnerability is due to insufficient file system permissions on an affected device. An attacker could exploit this vulnerability by connecting to an affected device's guest shell, and accessing or modifying restricted files. A successful exploit could allow the attacker to view or modify restricted information or configurations that are normally not accessible to system administrators. Una vulnerabilidad en los permisos del sistema de archivos de Cisco IOS XE Software, podría permitir a un atacante local autenticado conseguir acceso de lectura y escritura a la configuración crítica o archivos del sistema. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-unauth-file-access-eBTWkKVW • CWE-284: Improper Access Control CWE-732: Incorrect Permission Assignment for Critical Resource •

A vulnerability in the Ethernet packet handling of Cisco Aironet Access Points (APs) Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by connecting as a wired client to the Ethernet interface of an affected device and sending a series of specific packets within a short time frame. A successful exploit could allow the attacker to cause a NULL pointer access that results in a reload of the affected device. Una vulnerabilidad en el manejo de paquetes Ethernet de Cisco Aironet Access Points (APs) Software, 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-ap-ethport-dos-xtjTt8pY • CWE-476: NULL Pointer Dereference •

A vulnerability in Cisco Aironet Access Point (AP) Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to improper handling of clients that are trying to connect to the AP. An attacker could exploit this vulnerability by sending authentication requests from multiple clients to an affected device. A successful exploit could allow the attacker to cause the affected device to reload. Una vulnerabilidad en Cisco Aironet Access Point (AP) Software, podría permitir a un atacante remoto no autenticado causar la recarga de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aironet-dos-h3DCuLXw • CWE-400: Uncontrolled Resource Consumption •

A vulnerability in Cisco Aironet Access Points (APs) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) on an affected device. The vulnerability is due to improper resource management while processing specific packets. An attacker could exploit this vulnerability by sending a series of crafted UDP packets to a specific port on an affected device. A successful exploit could either allow the attacker to tear down the connection between the AP and the wireless LAN controller, resulting in the affected device not being able to process client traffic, or cause the vulnerable device to reload, triggering a DoS condition. After the attack, the affected device should automatically recover its normal functions without manual intervention. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aironet-dos-VHr2zG9y • CWE-400: Uncontrolled Resource Consumption •

A vulnerability in the Flexible NetFlow Version 9 packet processor of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper validation of parameters in a Flexible NetFlow Version 9 record. An attacker could exploit this vulnerability by sending a malformed Flexible NetFlow Version 9 packet to the Control and Provisioning of Wireless Access Points (CAPWAP) data port of an affected device. An exploit could allow the attacker to trigger an infinite loop, resulting in a process crash that would cause a reload of the device. Una vulnerabilidad en el procesador de paquetes Flexible NetFlow Versión 9 de Cisco IOS XE Software para los controladores inalámbricos Cisco Catalyst serie 9800, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-fnfv9-dos-HND6Fc9u • CWE-20: Improper Input Validation •
