[github.com/gravitl/netmaker] Netmaker before 0.15.1 vulnerable to Insufficient Granularity of Access Control

Impact

Improper Authorization functions leads to non-privileged users running privileged API calls. If you have added users to your Netmaker platform who whould not have admin privileges, they could use their auth token to run admin-level functions via the API.

In addition, differing response codes based on function calls allowed non-users to potentially brute force the determination of names of networks on the system.

Patches

This problem has been patched in v0.15.1. To apply:

1. docker-compose down
2. docker pull gravitl/netmaker:v0.15.1
3. docker-compose up -d
