VNX-41 – Improper Resolution of Path Equivalence

Overview

VNX-41 maps to CWE-41: Improper Resolution of Path Equivalence. Detects source patterns associated with CWE-41 (Improper Resolution of Path Equivalence). Each finding should be manually reviewed for exploitability in context.

Severity: Medium | CWE: CWE-41 | Languages: java, node, python

Why This Matters

This weakness class (Improper Resolution of Path Equivalence) creates a concrete exploit surface: the rule searches for the concrete source-level patterns most commonly associated with CWE-41 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 'open(' pattern
open(

// FLAGGED: contains 'path.join(' pattern
path.join(

// FLAGGED: contains 'new File(' pattern
new File(

Remediation

  1. Review each flagged line and determine whether the pattern represents a real instance of CWE-41 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-41 comment on the line.
  4. Ensure equivalent test coverage exists to prevent regression.
