CVE-2023-51649 · Severity: low · CVSS 3.5 · Published 2023-12-22

Nautobot is a platform used for managing network infrastructure and automating IT tasks. A security flaw was found where users with permission to run a single automation task (Job) could bypass restrictions and run any task configured as a 'Job Button.' This could allow unauthorized users to perform administrative actions or disrupt network operations they should not have access to.

## Technical details

An authorization bypass exists in Nautobot's Job Button execution logic. When a user invokes a Job via the `/extras/job-button/<uuid>/run/` endpoint, the application only verifies the model-level 'extras.run_job' permission rather than checking if the user has object-level permissions for that specific Job instance. This vulnerability specifically affects Jobs implemented as subclasses of 'JobButtonReceiver'. Additionally, the 'extras.run_jobbutton' permission was found to be unenforced by the backend view, relying solely on UI-level obfuscation. Attackers with low privileges (any job execution rights) can exploit this over the network to execute unauthorized automation tasks. The issue is resolved in versions 1.6.8 and 2.1.0.
