Description

This security bulletin contains information about 1 vulnerability.


1) Improper Authorization (CVE-ID: N/A)

CWE-ID: CWE-285 - Improper Authorization

CVSSv4: 5.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to disclose sensitive information.

The vulnerability exists due to improper authorization in the legacy \"connections\" REST API endpoints when handling requests for connection data. A remote user can query the affected endpoints to disclose sensitive information.

The issue affects the `/api/dcim/console-connections/` and `/api/dcim/power-connections/` endpoints, and also `/api/dcim/interface-connections/` on the 2.4.x line only. Object-level permission constraints are silently ignored while model-level permission is still enforced.
