WAGO: Multiple vulnerabilities in web-based management of multiple products
The Web-Based Management (WBM) of WAGOs programmable logic controller (PLC) is typically used for administration, commissioning and updates. The configuration backend can in some cases be used without authentication and to write data with root privileges. Additionally, the web-based management suffers a CORS misconfiguration and allows reflected XSS (Cross-Site Scripting) attacks.
