Severity ?
8.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Summary
A vulnerability in the virtual console authentication 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 but low-privileged, local attacker to log in to the Virtual Device Server (VDS) of an affected device by using a set of default credentials. The vulnerability is due to the presence of weak, hard-coded credentials. An attacker could exploit this vulnerability by authenticating to the targeted device and then connecting to VDS through the device’s virtual console by using the static credentials. A successful exploit could allow the attacker to access the Linux shell of VDS as the root user.

The vulnerability is due to the presence of weak, hard-coded credentials. An attacker could exploit this vulnerability by authenticating to the targeted device and then connecting to VDS through the device\u0026rsquo;s virtual console by using the static credentials. A successful exploit could allow the attacker to access the Linux shell of VDS as the root user."

La vulnerabilidad es debido a la presencia de credenciales d\u00e9biles y embebidas. Un atacante podr\u00eda explotar esta vulnerabilidad al autenticarse en el dispositivo objetivo y luego conectarse a VDS por medio de la consola virtual device\u2019s usando las credenciales est\u00e1ticas. Una explotaci\u00f3n con \u00e9xito podr\u00eda permitir al atacante acceder al shell de VDS de Linux como usuario root."
