RFID disclosure via unauthenticated web request
Published Apr 27, 2022 · Updated Sep 16, 2024
Information disclosure in Bender/ebee Charge Controllers allows remote attackers to read the last charging event's RFID through the web interface. The web interface returns the stored RFID from the most recent charge event without performing an authentication check. Network reachability is sufficient; the reported consequence is disclosure of the identifier, with no reported data modification or service interruption.
