Use of Hard-coded Cryptographic Key in Netmaker

CVE-2022-23650 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

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:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
