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))
