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.
