## Affected

- ZkTeco ZkTeco-based OEM devices with firmware ZAM170-NF-1.8.25-7354-Ver1.0.0, Standalone service v. 2.1.6-20200907: ZAM170-NF-1.8.25-7354-Ver1.0.0, Standalone service v. 2.1.6-20200907

## Description

An 'SQL Injection' vulnerability, due to improper neutralization of special elements used in SQL commands, exists in ZKTeco-based OEM devices. This vulnerability allows an attacker to, in some cases, impersonate another user or perform unauthorized actions. In other instances, it enables the attacker to access user data and system parameters from the database. This issue affects ZkTeco-based OEM devices (ZkTeco ProFace X, Smartec ST-FR043, Smartec ST-FR041ME and possibly others) with firmware ZAM170-NF-1.8.25-7354-Ver1.0.0 and possibly other, Standalone service v. 2.1.6-20200907 and possibly others.
