The 9.8 out of 10 severity bug, CVE-2020-3227, concerns the authorization controls for the Cisco IOx application hosting infrastructure in Cisco IOS XE Software, which allows a remote attacker without credentials to execute Cisco IOx API commands without proper authorization.
CVE-2020-3205 is a command-injection vulnerability in Cisco's 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). The software doesn't adequately validate signaling packets directed to the Virtual Device Server (VDS), which could allow an attacker to send malicious packets to an affected device, gain control of VDS and then completely compromise the system, including the IOS VM and guest VM. VDS handles access to devices that are shared by IOS and the guest OS, such as flash memory, USB ports, and the console. "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," Cisco said. "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."
