Arbitrary File Write in cli

Affected versions of cli use predictable temporary file names. If an attacker can create a symbolic link at the location of one of these temporarly file names, the attacker can arbitrarily write to any file that the user which owns the cli process has permission to write to.

Proof of Concept

By creating Symbolic Links at the following locations, the target of the link can be written to.

lock_file = '/tmp/' + cli.app + '.pid',
log_file = '/tmp/' + cli.app + '.log';

Recommendation

Update to version 1.0.0 or later.
