PiiGAB M-Bus is vulnerable to cross-site request forgery. An attacker who wants to execute a certain command could send a phishing mail to the owner of the device and hope that the owner clicks on the link. If the owner of the device has a cookie stored that allows the owner to be logged in, then the device could execute the GET or POST link request.

Workaround:
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
