A web application for configuring the controller is accessible at a specific path. It contains an endpoint that allows a high privileged remote attacker to read files from the system’s file structure.

A web application for configuring the controller is accessible at a specific path. It contains an endpoint that allows an unauthenticated remote attacker to read files from the system’s file structure.

Vulnerabilities have been discovered in the WAGO Device Manager that allow any origin to access the server and set header values, as well as an endpoint that permits read access to the file system. The WAGO Device Manager is a software for configuring and parameterizing single WAGO products, which is included in the firmware. These vulnerabilities could be exploited by attackers to send requests and read server responses through crafted web applications or to access the file system.
