B601: Test for shell injection within Paramiko¶
Paramiko is a Python library designed to work with the SSH2 protocol for secure (encrypted and authenticated) connections to remote machines. It is intended to run commands on a remote host. These commands are run within a shell on the target and are thus vulnerable to various shell injection attacks. Bandit reports a MEDIUM issue when it detects the use of Paramiko’s “exec_command” method advising the user to check inputs are correctly sanitized.
>> Issue: Possible shell injection via Paramiko call, check inputs are properly sanitized. Severity: Medium Confidence: Medium Location: ./examples/paramiko_injection.py:4 3 # this is not safe 4 paramiko.exec_command('something; really; unsafe') 5
