A vulnerability in the IP packet processing of Cisco Access Point (AP) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of certain IPv4 packets. An attacker could exploit this vulnerability by sending a crafted IPv4 packet either to or through an affected device. A successful exploit could allow the attacker to cause an affected device to reload unexpectedly, resulting in a DoS condition. To successfully exploit this vulnerability, the attacker does not need to be associated with the affected AP. This vulnerability cannot be exploited by sending IPv6 packets. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-dos-h9TGGX6W • CWE-20: Improper Input Validation •

A vulnerability in the boot process of Cisco Access Point (AP) Software could allow an unauthenticated, physical attacker to bypass the Cisco Secure Boot functionality and load a software image that has been tampered with on an affected device. This vulnerability exists because unnecessary commands are available during boot time at the physical console. An attacker could exploit this vulnerability by interrupting the boot process and executing specific commands to bypass the Cisco Secure Boot validation checks and load an image that has been tampered with. This image would have been previously downloaded onto the targeted device. A successful exploit could allow the attacker to load the image once. The Cisco Secure Boot functionality is not permanently compromised. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-secureboot-bypass-zT5vJkSD • CWE-501: Trust Boundary Violation •

A vulnerability in auxiliary asynchronous port (AUX) functions of Cisco IOS XE Software could allow an authenticated, local attacker to cause an affected device to reload or stop responding. This vulnerability is due to the incorrect handling of specific ingress traffic when flow control hardware is enabled on the AUX port. An attacker could exploit this vulnerability by reverse telnetting to the AUX port and sending specific data after connecting. A successful exploit could allow the attacker to cause the device to reset or stop responding, resulting in a denial of service (DoS) condition. Una vulnerabilidad en las funciones del puerto asíncrono auxiliar (AUX) del software Cisco IOS XE podría permitir que un atacante local autenticado provoque que un dispositivo afectado se recargue o deje de responder. Esta vulnerabilidad se debe al manejo incorrecto del tráfico de entrada específico cuando el hardware de control de flujo está habilitado en el puerto AUX. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aux-333WBz8f • CWE-828: Signal Handler with Functionality that is not Asynchronous-Safe •

A vulnerability in the multicast DNS (mDNS) gateway feature of Cisco IOS XE Software for Wireless LAN Controllers (WLCs) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper management of mDNS client entries. An attacker could exploit this vulnerability by connecting to the wireless network and sending a continuous stream of specific mDNS packets. A successful exploit could allow the attacker to cause the wireless controller to have high CPU utilization, which could lead to access points (APs) losing their connection to the controller and result in a DoS condition. Una vulnerabilidad en la función de puerta de enlace DNS de multidifusión (mDNS) del software Cisco IOS XE para controladores de LAN inalámbrica (WLC) podría permitir que un atacante adyacente no autenticado provoque una condición de denegación de servicio (DoS). Esta vulnerabilidad se debe a una gestión inadecuada de las entradas del cliente mDNS. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wlc-mdns-dos-4hv6pBGf • CWE-459: Incomplete Cleanup •

A vulnerability in the IPv4 Software-Defined Access (SD-Access) fabric edge node feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause high CPU utilization and stop all traffic processing, resulting in a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of certain IPv4 packets. An attacker could exploit this vulnerability by sending certain IPv4 packets to an affected device. A successful exploit could allow the attacker to cause the device to exhaust CPU resources and stop processing traffic, resulting in a DoS condition. Una vulnerabilidad en la función de nodo de borde de la estructura de acceso definido por software (SD-Access) IPv4 del software Cisco IOS XE podría permitir que un atacante remoto no autenticado cause una alta utilización de la CPU y detenga todo el procesamiento del tráfico, lo que resultaría en una denegación de servicio (DoS). condición en un dispositivo afectado. Esta vulnerabilidad se debe al manejo inadecuado de ciertos paquetes IPv4. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-sda-edge-dos-qZWuWXWG • CWE-783: Operator Precedence Logic Error •
