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 •
CVSS: 9.1EPSS: 0%CPEs: 996EXPL: 0CVE-2023-20186
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 •
CVSS: 8.6EPSS: 0%CPEs: 852EXPL: 0CVE-2023-20080 – Cisco IOS and IOS XE Software IPv6 DHCP (DHCPv6) Relay and Server Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2023-20080
A vulnerability in the IPv6 DHCP version 6 (DHCPv6) relay and server features of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to trigger a denial of service (DoS) condition. This vulnerability is due to insufficient validation of data boundaries. An attacker could exploit this vulnerability by sending crafted DHCPv6 messages to an affected device. A successful exploit could allow the attacker to cause the device to reload unexpectedly. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-dhcpv6-dos-44cMvdDK • CWE-129: Improper Validation of Array Index •

https://notcve.org/view.php?id=CVE-2022-20920
A vulnerability in the SSH implementation of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to cause an affected device to reload. This vulnerability is due to improper handling of resources during an exceptional situation. An attacker could exploit this vulnerability by continuously connecting to an affected device and sending specific SSH requests. A successful exploit could allow the attacker to cause the affected device to reload. Una vulnerabilidad en la implementación de SSH del software Cisco IOS y del software Cisco IOS XE podría permitir que un atacante remoto autenticado causara la recarga de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ssh-excpt-dos-FzOBQTnk • CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 7.6EPSS: 0%CPEs: 214EXPL: 1CVE-2022-20724 – Cisco IOx Application Hosting Environment Vulnerabilities
https://notcve.org/view.php?id=CVE-2022-20724
Multiple vulnerabilities in the Cisco IOx application hosting environment on multiple Cisco platforms could allow an attacker to inject arbitrary commands into the underlying host operating system, execute arbitrary code on the underlying host operating system, install applications without being authenticated, or conduct a cross-site scripting (XSS) attack against a user of the affected software. For more information about these vulnerabilities, see the Details section of this advisory. Múltiples vulnerabilidades en el entorno de alojamiento de aplicaciones Cisco IOx en varias plataformas de Cisco podrían permitir a un atacante inyectar comandos arbitrarios en el sistema operativo anfitrión subyacente, ejecutar código arbitrario en el sistema operativo anfitrión subyacente, instalar aplicaciones sin estar autenticado o conducir un ataque de tipo cross-site scripting (XSS) contra un usuario del software afectado.
