Use of Hard-coded Cryptographic Key in Netmaker

High severity GitHub Reviewed Published Feb 18, 2022 in gravitl/netmaker • Updated Feb 3, 2023

Package

gomod github.com/gravitl/netmaker (Go)

Affected versions

< 0.8.5
>= 0.9.0, < 0.9.4

Patched versions

0.8.5
0.9.4

Description

Impact

There is a hard-coded cryptographic key in the code base which can be exploited to run admin commands on a remote server, if you know the address and username of the admin. This effects the server (netmaker) component, and not clients.

Patches

This has been patched in Netmaker v0.8.5, v0.9.4, and v0.10.0. If you are running these versions, the fix is to perform the following:

  1. docker-compose down
  2. docker pull gravitl/netmaker:( version )
  3. docker-compose up -d

Additional Information

If you are running any other version, you will need to upgrade to one of these three versions. If you have a special circumstance that requires running a different version, let us know and we may be able to build a custom patch.

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.
