CVSS: 6.6EPSS: 1%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 •

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 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 •

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 •

A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker to perform an injection attack against an affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted input to the web UI. A successful exploit could allow the attacker to execute arbitrary Cisco IOS XE Software CLI commands with level 15 privileges. Note: This vulnerability is exploitable only if the attacker obtains the credentials for a Lobby Ambassador account. This account is not configured by default. Una vulnerabilidad en la interfaz de usuario web del software Cisco IOS XE podría permitir que un atacante remoto autenticado realice un ataque de inyección contra un dispositivo afectado. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webui-cmdij-FzZAeXAy • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
