re:trace — CISCO ASA5506-X V05

Executive Summary

Analysis of CISCO ASA5506-X V05 identified 177 components (43 with part number matches) and 88 traces. Security scan detected 1 HIGH, 4 MEDIUM severity findings (max CVSS 7.6). 1 exposed debug interface requiring physical access controls. Mapped to MITRE ATT&CK techniques: T0839, T0845, T1200.

Methodology

This assessment was performed using automated PCB reverse engineering techniques:

Component Detection — YOLO v8 object detection with OpenCV contour fallback for air-gapped environments.
OCR & Identification — EasyOCR marking extraction with fuzzy matching against a 128-part component database.
Trace Extraction — Dual-space (HSV+LAB) color segmentation with Zhang-Suen skeletonization for copper trace mapping.
Constraint Inference — AC-3 arc consistency propagation to infer connections not directly visible.
Security Analysis — Pattern-matched debug interface detection with CVSS 3.1 scoring and MITRE ATT&CK mapping.

Findings are classified per CVSS v3.1 (physical access vector). CWE references follow MITRE CWE v4.x. ATT&CK technique IDs reference both Enterprise (T1200) and ICS (T0839, T0845) matrices.
