Vulnerability details
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…
more
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 user's `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.

Why these techniques?
The vulnerability allows low-privileged users (extras.view_dynamicgroup) to enumerate and list details of dynamic group members (e.g., devices) via UI and REST API without enforcing object-specific permissions (e.g., dcim.view_device), facilitating remote system discovery and collection from an information repository.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Provides defined handling (alert and additional actions) for the exceptional condition of audit logging failure.
Supplies a concrete handling action (safe mode) for exceptional conditions, mitigating risks from improper or absent handling that could allow continued attacks.
By preparing users for contingency scenarios, the control promotes proper handling of exceptional conditions instead of default or unsafe behaviors.
An updated contingency plan defines current actions for exceptional conditions, reducing the window for attackers to exploit improper handling leading to system failure.
Procedures ensure proper handling of exceptional conditions to support effective incident response.
Incident response testing confirms proper handling of exceptional conditions to limit exploit impact.
Gives users guidance on incident handling, reducing improper handling of exceptional conditions that could stem from exploited weaknesses.
Enforces structured response to exceptional conditions so the system cannot remain in an unsafe state.
