  B104: Test for binding to all interfaces
  ========================================
  
  Binding to all network interfaces can potentially open up a service to traffic
  on unintended interfaces, that may not be properly documented or secured. This
  plugin test looks for a string pattern "0.0.0.0" that may indicate a hardcoded
  binding to all network interfaces.
  
  :Example:
  
  .. code-block:: none
  
      >> Issue: Possible binding to all interfaces.
         Severity: Medium   Confidence: Medium
         CWE: CWE-605 (https://cwe.mitre.org/data/definitions/605.html)
         Location: ./examples/binding.py:4
      3   s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
      4   s.bind(('0.0.0.0', 31137))
      5   s.bind(('192.168.0.1', 8080))
