Rewterz Threat Advisory – CVE-2020-3205 – Cisco IOS Software for Cisco Industrial Routers Virtual Device Server Inter-VM Channel Command Injection Vulnerability

Severity

High

Analysis Summary

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.
