Description

The password is stored in a file named spaces in this filename in the home directory. Passing the name unquoted to cat splits it into separate arguments.

Overview

• Spaces in filenames are word-splitting characters for the shell.
• Quoting the name ("spaces in this filename") or escaping each space (spaces\ in\ this\ filename) passes it as a single argument.

Solution

• Quote the filename to prevent word splitting.

channel = connect.system('cat "spaces in this filename"')
result = channel.recv().decode().strip()
