F12: Protocol authentication disabled by default (V3.6.3.1)

← All findings · Repository

Document type: local CVE candidate assessment, not a published CVE Record. CVE ID: unassigned. Product scope: Anpviz IPC-D240W-S V3.5.2.1 captured from the owner’s MCA40E camera; the V3.6.3.1 comparison image is an MCA50E image sent in error and was not flashed to this model.

Finding

The shipped parser defaults leave ONVIF, HIK and DAHUA authentication off in both reviewed images.

Status in this image: unchanged or not remediated in supplied MCA50E image.

Evidence limit: Exact reachable operations depend on deployment settings and protocol handlers; RTSP authentication is separate.

Classification and severity

• Proposed CWE: CWE-306, CWE-1188
• CVSS v4.0 score: Not scored — current evidence does not support a defensible numeric impact/attack vector, this version lacks the issue, or the specific defect was fixed.
• CVSS v4.0 vector: Not assigned.
• Scoring basis: Exact reachable operations depend on deployment settings and protocol handlers; RTSP authentication is separate.
• CVE candidacy: Needs coordinator/CNA review for grouping, affected models and version status; do not equate this finding ID with a CVE ID.
