OS command injection affects Altenergy Power Control Software C1.2.5 via shell metacharacters in the index.php/management/set_timezone timezone parameter, because of set_timezone in models/management_model.php.
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.
