Multiple command injection in ZkTeco-based OEM devices

Improper Neutralization of Special Elements used in an OS Command ('OS
Command Injection') vulnerability in ZkTeco-based OEM devices allows OS
Command Injection.
Since all the found command implementations are executed from the
superuser, their impact is the maximum possible.
This issue affects
ZkTeco-based OEM devices (ZkTeco ProFace X, Smartec ST-FR043, Smartec
ST-FR041ME and possibly others) with the ZAM170-NF-1.8.25-7354-Ver1.0.0
and possibly other.
