{"id":"CVE-2023-51649","aliases":["GHSA-vf5m-xrhm-v999","PYSEC-2023-287"],"url":"https://o3.security/vulnerability/CVE-2023-51649","summary":"Nautobot missing object-level permissions enforcement when running Job Buttons","details":"### Impact\n\nWhen submitting a Job to run via a Job Button, only the model-level `extras.run_job` permission is checked (i.e., does the user have permission to run Jobs in general?). Object-level permissions (i.e., does the user have permission to run this *specific* Job?) are not enforced by the URL/view used in this case (`/extras/job-button/<uuid>/run/`) The effect is that a user with permissions to run even a single Job can actually run all configured JobButton Jobs.\n\n> Not all Jobs can be configured as JobButtons; only those implemented as subclasses of `JobButtonReceiver` can be used in this way, so this vulnerability only applies specifically to `JobButtonReceiver` subclasses.\n\nAdditionally, although the documentation states that both `extras.run_job` permission and `extras.run_jobbutton` permission must be granted to a user in order to run Jobs via JobButton, the `extras.run_jobbutton` permission is not actually enforced by the view code, only by the UI by disabling the button from being clicked normally. Furthermore, the `extras.run_jobbutton` permission never prevented invoking Jobs (including `JobButtonReceiver` subclasses) via the normal \"Job Run\" UI, so after some discussion, we've decided that the `extras.run_jobbutton` permission is redundant, and as it never achieved its stated/documented purpose, the fixes below will remove the UI check for `extras.run_jobbutton` and all other references to the `extras.run_jobbutton` permission, rather than adding enforcement of this previously unenforced permission.\n\n### Patches\n_Has the problem been patched? What versions should users upgrade to?_\n\nFix will be available in Nautobot 1.6.8 (https://github.com/nautobot/nautobot/pull/4995) and 2.1.0 (https://github.com/nautobot/nautobot/pull/4993)\n\n### Workarounds\n_Is there a way for users to fix or remediate the vulnerability without upgrading?_\n\nPartial mitigation can be achieved by auditing `JobButtonReceiver` subclasses defined in the system and restricting which users are permitted to create or edit JobButton records. \n\n### References\n\n- https://github.com/nautobot/nautobot/issues/4988\n- https://github.com/nautobot/nautobot/pull/4993\n- https://github.com/nautobot/nautobot/pull/4995","published":"2023-12-22T16:48:19.711Z","modified":"2026-10-28T02:30:43.629719047Z","cvss":{"score":3.5,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"nautobot","fixedVersion":"1.6.8"},{"ecosystem":"PyPI","name":"nautobot","fixedVersion":"2.1.0"}],"fix":{"url":"https://github.com/nautobot/nautobot/pull/4993","label":"nautobot/nautobot#4993"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/51xxx/CVE-2023-51649.json"},{"type":"ADVISORY","url":"https://github.com/nautobot/nautobot/security/advisories/GHSA-vf5m-xrhm-v999"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-51649"},{"type":"REPORT","url":"https://github.com/nautobot/nautobot/issues/4988"},{"type":"FIX","url":"https://github.com/nautobot/nautobot/pull/4993"},{"type":"FIX","url":"https://github.com/nautobot/nautobot/pull/4995"},{"type":"WEB","url":"https://github.com/nautobot/nautobot/commit/3d964f996f4926126c1d7853ca87b2ff475997a2"},{"type":"WEB","url":"https://github.com/nautobot/nautobot/commit/d33d0c15a36948c45244e5b5e10bc79b8e62de7f"},{"type":"PACKAGE","url":"https://github.com/nautobot/nautobot"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/nautobot/PYSEC-2023-287.yaml"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:43.629719047Z"}}
