DescriptionCVE.org

ZoneMinder before 1.38.4 fails to apply per-monitor access restrictions in the FramesController index endpoint. Authenticated users with Events view permission can call the frames API to list frame records from monitors they are denied access to, disclosing event and frame metadata across monitor boundaries.

AnalysisAI

Broken access control in ZoneMinder's Frames API lets an authenticated user who holds the 'Events' view permission but is explicitly denied access to one or more monitors enumerate frame and event metadata belonging to those restricted monitors. Affected are all ZoneMinder releases before 1.38.4 whenever per-monitor access restrictions are configured; the flaw is a single authenticated GET-style call to the FramesController index endpoint, requires no user interaction and no administrative rights, and is confirmed by the CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N as a low-confidentiality-impact information disclosure only. …
