A Command injection vulnerability in RaspAP 2.8.0 thru 2.8.7 allows unauthenticated attackers to execute arbitrary commands via the cfg_id parameter in /ajax/openvpn/activate_ovpncfg.php and /ajax/openvpn/del_ovpncfg.php.
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
