Why This Matters

This weakness class (Misinterpretation of Input) creates a concrete exploit surface: the rule searches for the concrete source-level patterns most commonly associated with CWE-115 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 'int(' pattern
int(

// FLAGGED: contains 'parseInt(' pattern
parseInt(

// FLAGGED: contains '$_GET' pattern
$_GET

Remediation

  1. Review each flagged line and determine whether the pattern represents a real instance of CWE-115 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-115 comment on the line.
  4. Ensure equivalent test coverage exists to prevent regression.
