In multiple CODESYS products, file download and upload function allows access to internal files in the working directory e.g. firmware files of the PLC. All requests are processed on the controller only if no level 1 password is configured on the controller or if remote attacker has previously successfully authenticated himself to the controller. A successful Attack may lead to a denial of service, change of local files, or drain of confidential Information. User interaction is not required
