CWE: CWE-78 \u2014 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.

Code:
    def run(self, info):
        for tmpl in self.exec_cmd:
            cmd = self.parse_cmd(tmpl, info)
            self.to_screen('Executing command: %s' % cmd)
            retCode = subprocess.call(encodeArgument(cmd), shell=True)
            if retCode != 0:
                raise PostProcessingError('Command returned error code %d' % retCode)
        return [], info
