Vulnerability from github – Published: 2023-07-07 00:30 – Updated: 2024-04-04 05:50

Details

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.

Severity

8.8 (High)
