← 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

Reset calls appear in SDK tools, but no receiving firmware component was found in either image.

Status in this image: original finding or lead.

Evidence limit: No dedicated C export or confirmed affected product; this is an open lead, not a verified vulnerability.

Classification and severity

  • Proposed CWE: CWE-306
  • 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: No dedicated C export or confirmed affected product; this is an open lead, not a verified vulnerability.
  • 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.
