Indicators of Compromise

All CLI commands sent to devices are logged in by the device-interaction app in lines that start with “Request to execute:”. These logs along with device Radius/TACACS logs can be checked for suspicious activity.

Mitigation

The workaround is to append the following to /etc/nginx/conf.d/locations/cvp.https.conf on all CVP nodes:

location ^~ /cvpservice/di/ {
    return 404;
}
 

Then restart nginx by running the following command on any node:

nginx-app.sh reload
