Nautobot is a Network Source of Truth and Network Automation Platform. A user with permissions to view Dynamic Group records (extras.view_dynamicgroup permission) can use the Dynamic Group detail UI view (/extras/dynamic-groups/<uuid>/) and/or the members REST API view (/api/extras/dynamic-groups/<uuid>/members/) to list the objects that are members of a given Dynamic Group. In versions of Nautobot between 1.3.0 (where the Dynamic Groups feature was added) and 1.6.22 inclusive, and 2.0.0 through 2.2.4 inclusive, Nautobot fails to restrict these listings based on the member object permissions - for example a Dynamic Group of Device objects will list all Devices that it contains, regardless of the users dcim.view_device permissions or lack thereof. This issue has been fixed in Nautobot versions 1.6.23 and 2.2.5. Users are advised to upgrade. This vulnerability can be partially mitigated by removing extras.view_dynamicgroup permission from users however a full fix will require upgrading.

Weakness

The product does not handle or incorrectly handles when it has insufficient privileges to access resources or functionality as specified by their permissions. This may cause it to follow unexpected code paths that may leave the product in an invalid state.

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
