How to fix?

Upgrade nautobot to version 1.6.16, 2.1.9 or higher.

Overview

nautobot is a Source of truth and network automation platform.

Affected versions of this package are vulnerable to Information Exposure due to improper access control on several URL endpoints. An attacker can access sensitive information without authentication by exploiting endpoints that are improperly accessible to unauthenticated users. This includes endpoints that may disclose information about the system's authentication backend classes, supported secrets providers, and potentially sensitive logs associated with specific JobResults.

Note:

This is only exploitable if the Nautobot configuration variable EXEMPT_VIEW_PERMISSIONS is altered from its default value to permit access to specific data by unauthenticated users.

Workaround

This vulnerability can be mitigated by reverting the EXEMPT_VIEW_PERMISSIONS configuration to its default value, thus preventing exposure of information to unauthenticated users via the affected endpoints.
