CVSS: 7.2EPSS: 0%CPEs: 17EXPL: 0CVE-2021-1371 – Cisco IOS XE SD-WAN Software Console Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-1371
A vulnerability in the role-based access control of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker with read-only privileges to obtain administrative privileges by using the console port when the device is in the default SD-WAN configuration. This vulnerability occurs because the default configuration is applied for console authentication and authorization. An attacker could exploit this vulnerability by connecting to the console port and authenticating as a read-only user. A successful exploit could allow a user with read-only permissions to access administrative privileges. Una vulnerabilidad en el control de acceso basado en roles del Software Cisco IOS XE SD-WAN, podría permitir a un atacante local autenticado con privilegios de solo lectura obtener privilegios administrativos utilizando el puerto de la consola cuando el dispositivo está en la configuración SD-WAN predeterminada. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdwan-esc-rSNVvTf9 • CWE-269: Improper Privilege Management •
CVSS: 10.0EPSS: 0%CPEs: 7EXPL: 0CVE-2020-3375 – Cisco SD-WAN Solution Software Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2020-3375
A vulnerability in Cisco SD-WAN Solution Software could allow an unauthenticated, remote attacker to cause a buffer overflow on an affected device. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to gain access to information that they are not authorized to access, make changes to the system that they are not authorized to make, and execute commands on an affected system with privileges of the root user. Una vulnerabilidad en Cisco SD-WAN Solution Software podría permitir a un atacante remoto no autenticado causar un desbordamiento del búfer sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdbufof-h5f5VSeL • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.2EPSS: 0%CPEs: 7EXPL: 0CVE-2020-3216 – Cisco IOS XE SD-WAN Software Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3216
A vulnerability in Cisco IOS XE SD-WAN Software could allow an unauthenticated, physical attacker to bypass authentication and gain unrestricted access to the root shell of an affected device. The vulnerability exists because the affected software has insufficient authentication mechanisms for certain commands. An attacker could exploit this vulnerability by stopping the boot initialization of an affected device. A successful exploit could allow the attacker to bypass authentication and gain unrestricted access to the root shell of the affected device. Una vulnerabilidad en Cisco IOS XE SD-WAN Software, podría permitir a un atacante físico no autenticado omitir la autenticación y conseguir acceso sin restricciones al shell root de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-auth-b-NzwhJHH7 • CWE-287: Improper Authentication •
