VNX-321 – CWE-321

Overview

VNX-321 maps to CWE-321: CWE-321. Detects source patterns associated with CWE-321 (CWE-321). Each finding should be manually reviewed for exploitability in context.

Severity: High | CWE: CWE-321 | Languages: go, java, node, python

Why This Matters

This weakness class (CWE-321) creates a concrete exploit surface: the rule searches for the concrete source-level patterns most commonly associated with CWE-321 and surfaces them for review. Each finding should be evaluated in context — the rule catches the pattern, not the context.

What Gets Flagged

// FLAGGED: contains 'key = b"' pattern
key = b"

Remediation

  1. Review each flagged line and determine whether the pattern represents a real instance of CWE-321 or a false positive.
  2. Replace the flagged construct with a documented safe alternative appropriate to your language and framework.
  3. For confirmed false positives, add a # vulnetix-ignore: VNX-321 comment on the line.
  4. Ensure equivalent test coverage exists to prevent regression.
