CVE-2020-3198 – Cisco IOS Software for Cisco Industrial Routers Arbitrary Code Execution Vulnerabilities
https://notcve.org/view.php?id=CVE-2020-3198
Multiple vulnerabilities in Cisco IOS Software for Cisco 809 and 829 Industrial Integrated Services Routers (Industrial ISRs) and Cisco 1000 Series Connected Grid Routers (CGR1000) could allow an unauthenticated, remote attacker or an authenticated, local attacker to execute arbitrary code on an affected system or cause an affected system to crash and reload. For more information about these vulnerabilities, see the Details section of this advisory. Múltiples vulnerabilidades en Cisco IOS Software para Cisco 809 y 829 Industrial Integrated Services Routers (Industrial ISRs) y Cisco 1000 Series Connected Grid Routers (CGR1000), podrían permitir a un atacante remoto no autenticado o a un atacante local autenticado ejecutar código arbitrario en un sistema afectado o causar que un sistema afectado se bloquee y se vuelva a cargar. Para mayor información sobre estas vulnerabilidades, ver la sección de Detalles de este aviso. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-iot-rce-xYRSeMNH • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
CVE-2020-3210 – Cisco IOS Software for Cisco Industrial Routers Virtual Device Server CLI Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2020-3210
A vulnerability in the CLI parsers of Cisco IOS Software for Cisco 809 and 829 Industrial Integrated Services Routers (Industrial ISRs) and Cisco 1000 Series Connected Grid Routers (CGR1000) could allow an authenticated, local attacker to execute arbitrary shell commands on the Virtual Device Server (VDS) of an affected device. The attacker must have valid user credentials at privilege level 15. The vulnerability is due to insufficient validation of arguments that are passed to specific VDS-related CLI commands. An attacker could exploit this vulnerability by authenticating to the targeted device and including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands in the context of the Linux shell of VDS with the privileges of the root user. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-iot-vds-cmd-inj-VfJtqGhE • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2020-3208 – Cisco IOS Software for Cisco 800 Series Industrial Integrated Services Routers Image Verification Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3208
A vulnerability in the image verification feature of Cisco IOS Software for Cisco 809 and 829 Industrial Integrated Services Routers (Industrial ISRs) could allow an authenticated, local attacker to boot a malicious software image on an affected device. The vulnerability is due to insufficient access restrictions on the area of code that manages the image verification feature. An attacker could exploit this vulnerability by first authenticating to the targeted device and then logging in to the Virtual Device Server (VDS) of an affected device. The attacker could then, from the VDS shell, disable Cisco IOS Software integrity (image) verification. A successful exploit could allow the attacker to boot a malicious Cisco IOS Software image on the targeted device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-ir800-img-verif-wHhLYHjK • CWE-264: Permissions, Privileges, and Access Controls •
CVE-2020-3205 – Cisco IOS Software for Cisco Industrial Routers Virtual Device Server Inter-VM Channel Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2020-3205
A vulnerability in the implementation of the inter-VM channel of Cisco IOS Software for Cisco 809 and 829 Industrial Integrated Services Routers (Industrial ISRs) and Cisco 1000 Series Connected Grid Routers (CGR1000) could allow an unauthenticated, adjacent attacker to execute arbitrary shell commands on the Virtual Device Server (VDS) of an affected device. The vulnerability is due to insufficient validation of signaling packets that are destined to VDS. An attacker could exploit this vulnerability by sending malicious packets to an affected device. A successful exploit could allow the attacker to execute arbitrary commands in the context of the Linux shell of VDS with the privileges of the root user. Because the device is designed on a hypervisor architecture, exploitation of a vulnerability that affects the inter-VM channel may lead to a complete system compromise. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-iot-udp-vds-inj-f2D5Jzrt • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2019-12648 – Cisco IOx for IOS Software Guest Operating System Unauthorized Access Vulnerability
https://notcve.org/view.php?id=CVE-2019-12648
A vulnerability in the IOx application environment for Cisco IOS Software could allow an authenticated, remote attacker to gain unauthorized access to the Guest Operating System (Guest OS) running on an affected device. The vulnerability is due to incorrect role-based access control (RBAC) evaluation when a low-privileged user requests access to a Guest OS that should be restricted to administrative accounts. An attacker could exploit this vulnerability by authenticating to the Guest OS by using the low-privileged-user credentials. An exploit could allow the attacker to gain unauthorized access to the Guest OS as a root user. Una vulnerabilidad en el entorno de la aplicación IOx para Software Cisco IOS, podría permitir a un atacante remoto autenticado conseguir acceso no autorizado al Sistema Operativo Invitado (SO Invitado) que es ejecutado en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-ios-gos-auth • CWE-284: Improper Access Control CWE-863: Incorrect Authorization •
