A vulnerability in the Wireless Network Control daemon (wncd) of Cisco IOS XE Software for Wireless LAN Controllers could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper memory management. An attacker could exploit this vulnerability by sending a series of network requests to an affected device. A successful exploit could allow the attacker to cause the wncd process to consume available memory and eventually cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en el Wireless Network Control daemon (wncd) del software Cisco IOS XE para controladores de LAN inalámbrica 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 la memoria. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wlc-wncd-HFGMsfSD • CWE-789: Memory Allocation with Excessive Size Value •
CVSS: 6.6EPSS: 0%CPEs: 1040EXPL: 0CVE-2023-20109 – Cisco IOS and IOS XE Group Encrypted Transport VPN Out-of-Bounds Write Vulnerability
https://notcve.org/view.php?id=CVE-2023-20109
A vulnerability in the Cisco Group Encrypted Transport VPN (GET VPN) feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker who has administrative control of either a group member or a key server to execute arbitrary code on an affected device or cause the device to crash. This vulnerability is due to insufficient validation of attributes in the Group Domain of Interpretation (GDOI) and G-IKEv2 protocols of the GET VPN feature. An attacker could exploit this vulnerability by either compromising an installed key server or modifying the configuration of a group member to point to a key server that is controlled by the attacker. A successful exploit could allow the attacker to execute arbitrary code and gain full control of the affected system or cause the affected system to reload, resulting in a denial of service (DoS) condition. For more information, see the Details ["#details"] section of this advisory. Una vulnerabilidad en la función Cisco Group Encrypted Transport VPN (GET VPN) del software Cisco IOS y del software Cisco IOS XE podría permitir que un atacante remoto autenticado que tiene control administrativo de un miembro del grupo o de un servidor de claves ejecute código arbitrario en un dispositivo afectado o haga que el dispositivo se bloquee. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-getvpn-rce-g8qR68sx • CWE-787: Out-of-bounds Write •

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 •

https://notcve.org/view.php?id=CVE-2023-20227
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 Application Quality of Experience (AppQoE) and Unified Threat Defense (UTD) on Cisco IOS XE Software 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 the mishandling of a crafted packet stream through the AppQoE or UTD application. An attacker could exploit this vulnerability by sending a crafted packet stream through an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en la Application Quality of Experience (AppQoE) y en el Unified Threat Defense (UTD) en el software Cisco IOS XE 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 al mal manejo de un flujo de paquetes manipulado a través de la aplicación AppQoE o UTD. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-appqoe-utd-dos-p8O57p5y • CWE-456: Missing Initialization of a Variable •
