Overview

roar-pidusage is a Cross-platform process cpu % and memory usage of a PID — Edit

Affected versions of this package are vulnerable to Arbitrary Command Injection. If attacker-controlled user input is given to the stat function of this package on certain operating systems, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization.

PoC (provided by reporter):

var roar_pidusage = require('roar-pidusage');

roar_pidusage.stat('$(touch success)', function(){});

(A file called success will be created as a result of the execution of touch success.)

Note This affects operating systems associated with ps in the pusage {object}.
