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.
An unknown and undocumented configuration interface with limited functionality was identified on the affected devices.
A vulnerability in the web-based management (WBM) of WAGOs programmable logic controller (PLC) could allow an unauthenticated remote attacker to retrieve sensitive information.
The MAC address filter as part of the firewall has a flaw, which prevents the MAC address filter to be active after restart. In this way a remote attacker is able to circumvent the MAC address filtering after a reboot of a device.
UPDATE A: Solution has updated release dates
