The clustered setup of Apache MXNet allows users to specify which IP address and port the scheduler will listen on via the DMLC_PS_ROOT_URI and DMLC_PS_ROOT_PORT env variables. In versions older than 1.0.0, however, the MXNet framework will listen on 0.0.0.0 rather than user specified DMLC_PS_ROOT_URI once a scheduler node is initialized. This exposes the instance running MXNet to any attackers reachable via the interface they didn't expect to be listening on. For example: If a user wants to run a clustered setup locally, they may specify to run on 127.0.0.1. But since MXNet will listen on 0.0.0.0, it makes the port accessible on all network interfaces.

CVE-2018-1281 is considered a high severity vulnerability due to its potential for exposing applications to unauthorized access.
To fix CVE-2018-1281, upgrade Apache MXNet to version 1.0.0 or newer to ensure it listens only on specified IP addresses.
CVE-2018-1281 affects users of Apache MXNet versions older than 1.0.0 who deploy the framework in a clustered setup.
The impact of CVE-2018-1281 can lead to unauthorized access if the scheduler is exposed to untrusted networks.
If you cannot upgrade to fix CVE-2018-1281, consider implementing firewall rules to restrict access to the scheduler's IP and port.
