S104 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 "" that may indicate a hardcoded binding to all network interfaces.

  • Example
>> Issue: Possible binding to all interfaces.
   Severity: Medium   Confidence: Medium
   Location: ./examples/
3   s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
4   s.bind(('', 31137))
5   s.bind(('', 8080))
