F15: Cloud update verification (V3.6.3.1)

cannot decide statically

Last updated November 8, 2026

← 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

An older cloud FOTA/COTA client existed, but the client is absent from the supplied MCA50E image.

Status in this image: cannot decide statically.

Evidence limit: Device-side authentication and signature checks, and the MCA40E build status, cannot be decided from the exports.

Classification and severity

  • Proposed CWE: CWE-347, CWE-494
  • 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: Device-side authentication and signature checks, and the MCA40E build status, cannot be decided from the exports.
  • CVE candidacy: Needs coordinator/CNA review for grouping, affected models and version status; do not equate this finding ID with a CVE ID.

Source screenshots

The PNGs are rendered, line-numbered excerpts of existing Ghidra C-like decompilation, not photographs of the Ghidra GUI or recovered vendor source. The original export is authoritative; image selection can omit relevant lines elsewhere in the function.

  • No dedicated C export or code screenshot for this finding/version. See the case review and supporting evidence; no source was invented.
  • No verified related CVE linked to this specific finding; this is not an exhaustive database search.
