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.
>> Issue: Possible binding to all interfaces. Severity: Medium Confidence: Medium 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))
