Version Details and Security Vulnerabilities

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.

Versions of lodash.merge before 4.6.1 are vulnerable to Prototype Pollution. The function 'merge' may allow a malicious user to modify the prototype of Object via __proto__ causing the addition or modification of an existing property that will exist on all objects.

Recommendation

Update to version 4.6.1 or later.

Versions of lodash.merge before 4.6.2 are vulnerable to prototype pollution. The function merge may allow a malicious user to modify the prototype of Object via {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.

Recommendation

Update to version 4.6.2 or later.
