CVE-2025-70520
UnknownSummary
The websocket handler of Fanvil x7a firmware version 2.6.0.1182 does not enforce proper authentication restrictions against sessionless users. The lack of restrictions grants anyone the ability to view any device resources such as operational logs or perform diagnostic requests.
