Description

The powerd parameters powerd_ac_mode, powerd_battery_mode, and powerd_normal_mode are not validated against the list of expected mode strings in /usr/local/www/system_advanced_misc.php. They are also not escaped before use when invoking the powerd command inside activate_powerd() from /etc/inc/system.inc.

This can lead to an authenticated command injection for users with access to that page.
