https://notcve.org/view.php?id=CVE-2020-3141
Multiple vulnerabilities in the web management framework of Cisco IOS XE Software could allow an authenticated, remote attacker with read-only privileges to elevate privileges to the level of an Administrator user on an affected device. For more information about these vulnerabilities, see the Details section of this advisory. Múltiples vulnerabilidades en el framework de administración web de Cisco IOS XE Software, podrían permitir a un atacante remoto autenticado con privilegios de solo lectura elevar los privilegios al nivel de un usuario administrador en un dispositivo afectado. Para más información sobre estas vulnerabilidades, consulte la sección Detalles de este aviso. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-webui-priv-esc-K8zvEWM • CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 128EXPL: 0CVE-2020-3393 – Cisco IOS XE Software IOx Application Hosting Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3393
A vulnerability in the application-hosting subsystem of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to root on an affected device. The attacker could execute IOS XE commands outside the application-hosting subsystem Docker container as well as on the underlying Linux operating system. These commands could be run as the root user. The vulnerability is due to a combination of two factors: (a) incomplete input validation of the user payload of CLI commands, and (b) improper role-based access control (RBAC) when commands are issued at the command line within the application-hosting subsystem. An attacker could exploit this vulnerability by using a CLI command with crafted user input. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-iox-app-host-mcZcnsBt • CWE-20: Improper Input Validation CWE-269: Improper Privilege Management •
CVSS: 7.2EPSS: 0%CPEs: 56EXPL: 0CVE-2020-3396 – Cisco IOS XE Software IOx Guest Shell USB SSD Namespace Protection Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3396
A vulnerability in the file system on the pluggable USB 3.0 Solid State Drive (SSD) for Cisco IOS XE Software could allow an authenticated, physical attacker to remove the USB 3.0 SSD and modify sensitive areas of the file system, including the namespace container protections. The vulnerability occurs because the USB 3.0 SSD control data is not stored on the internal boot flash. An attacker could exploit this vulnerability by removing the USB 3.0 SSD, modifying or deleting files on the USB 3.0 SSD by using another device, and then reinserting the USB 3.0 SSD on the original device. A successful exploit could allow the attacker to remove container protections and perform file actions outside the namespace of the container with root privileges. Una vulnerabilidad en el sistema de archivos en la USB 3.0 Solid State Drive (SSD) conectable para el Cisco IOS XE Software, podría permitir a un atacante físico autenticado eliminar el SSD USB 3.0 y modificar áreas sensibles del sistema de archivos, incluyendo las protecciones del contenedor de espacio de nombres. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iox-usb-guestshell-WmevScDj • CWE-269: Improper Privilege Management CWE-284: Improper Access Control •
CVSS: 7.8EPSS: 0%CPEs: 128EXPL: 0CVE-2020-3404 – Cisco IOS XE Software Consent Token Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3404
A vulnerability in the persistent Telnet/Secure Shell (SSH) CLI of Cisco IOS XE Software could allow an authenticated, local attacker to gain shell access on an affected device and execute commands on the underlying operating system (OS) with root privileges. The vulnerability is due to insufficient enforcement of the consent token in authorizing shell access. An attacker could exploit this vulnerability by authenticating to the persistent Telnet/SSH CLI on an affected device and requesting shell access. A successful exploit could allow the attacker to gain shell access on the affected device and execute commands on the underlying OS with root privileges. Una vulnerabilidad en la CLI Telnet/Secure Shell (SSH) persistente de Cisco IOS XE Software, podría permitir a un atacante local autenticado obtener acceso de shell en un dispositivo afectado y ejecutar comandos en el sistema operativo (SO) subyacente con privilegios root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-ctbypass-7QHAfHkK • CWE-863: Incorrect Authorization •
CVSS: 8.6EPSS: 0%CPEs: 128EXPL: 0CVE-2020-3407 – Cisco IOS XE Software RESTCONF and NETCONF-YANG Access Control List Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3407
A vulnerability in the RESTCONF and NETCONF-YANG access control list (ACL) function of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the device to reload. The vulnerability is due to incorrect processing of the ACL that is tied to the RESTCONF or NETCONF-YANG feature. An attacker could exploit this vulnerability by accessing the device using RESTCONF or NETCONF-YANG. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en la función de lista de control de acceso (ACL) de RESTCONF y NETCONF-YANG de Cisco IOS XE Software, podría permitir a un atacante remoto no autenticado causar que el dispositivo se recargue. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-confacl-HbPtfSuO • CWE-476: NULL Pointer Dereference •
