https://notcve.org/view.php?id=CVE-2023-20186
A vulnerability in the Authentication, Authorization, and Accounting (AAA) feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to bypass command authorization and copy files to or from the file system of an affected device using the Secure Copy Protocol (SCP). This vulnerability is due to incorrect processing of SCP commands in AAA command authorization checks. An attacker with valid credentials and level 15 privileges could exploit this vulnerability by using SCP to connect to an affected device from an external machine. A successful exploit could allow the attacker to obtain or change the configuration of the affected device and put files on or retrieve files from the affected device. Una vulnerabilidad en la función Authentication, Authorization, and Accounting (AAA) del software Cisco IOS y del software Cisco IOS XE podría permitir a un atacante remoto autenticado eludir la autorización de ejecución de comandos y copiar archivos hacia o desde el sistema de archivos de un dispositivo afectado utilizando la función Secure Copy Protocol (SCP). Esta vulnerabilidad se debe al procesamiento incorrecto de los comandos SCP en las comprobaciones de autorización de comandos AAA. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aaascp-Tyj4fEJm • CWE-285: Improper Authorization •

A vulnerability in the Layer 2 Tunneling Protocol (L2TP) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of certain L2TP packets. An attacker could exploit this vulnerability by sending crafted L2TP packets to an affected device. A successful exploit could allow the attacker to cause the device to reload unexpectedly, resulting in a DoS condition. Note: Only traffic directed to the affected system can be used to exploit this vulnerability. Una vulnerabilidad en la función Layer 2 Tunneling Protocol (L2TP) del software Cisco IOS XE podría permitir que un atacante remoto no autenticado cause una condición de denegación de servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe al manejo inadecuado de ciertos paquetes L2TP. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-l2tp-dos-eB5tuFmV • CWE-388: 7PK - Errors •

A vulnerability in Cisco IOS XE Software for Cisco Catalyst 3650 and Catalyst 3850 Series Switches could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to improper resource management when processing traffic that is received on the management interface. An attacker could exploit this vulnerability by sending a high rate of traffic to the management interface. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en el software Cisco IOS XE para los Switches Cisco Catalyst 3650 y Catalyst 3850 Series podría permitir que un atacante remoto no autenticado provoque que un dispositivo afectado se recargue inesperadamente, lo que resultaría en una condición de denegación de servicio (DoS). Esta vulnerabilidad se debe a una gestión inadecuada de los recursos al procesar el tráfico que se recibe en la interfaz de gestión. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cat3k-dos-ZZA4Gb3r • CWE-770: Allocation of Resources Without Limits or Throttling •

A vulnerability in the Multicast Leaf Recycle Elimination (mLRE) feature of Cisco IOS XE Software for Cisco ASR 1000 Series Aggregation Services Routers could allow an unauthenticated, remote attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. This vulnerability is due to incorrect handling of certain IPv6 multicast packets when they are fanned out more than seven times on an affected device. An attacker could exploit this vulnerability by sending a specific IPv6 multicast or IPv6 multicast VPN (MVPNv6) packet through the affected device. A successful exploit could allow the attacker to cause a reload of the affected device, resulting in a DoS condition. Una vulnerabilidad en la función Multicast Leaf Recycle Elimination (mLRE) del software Cisco IOS XE para los Routers de Servicios de Agregación Cisco ASR serie 1000 podría permitir que un atacante remoto no autenticado provoque que el dispositivo afectado se recargue, lo que resultaría en una condición de denegación de servicio (DoS). • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-mlre-H93FswRz • CWE-823: Use of Out-of-range Pointer Offset •

https://notcve.org/view.php?id=CVE-2023-20056
A vulnerability in the management CLI of Cisco access point (AP) software could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of commands supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected command. A successful exploit could allow the attacker to cause an affected device to reload spontaneously, resulting in a DoS condition. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-cli-dos-tc2EKEpu • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
