Netmaker vulnerable to Insufficient Granularity of Access Control

High severity GitHub Reviewed Published Sep 9, 2022 in gravitl/netmaker • Updated Jun 27, 2023

Package

gomod github.com/gravitl/netmaker (Go)

Affected versions

< 0.15.1

Patched versions

0.15.1

Description

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

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
