Technical details

An authorization vulnerability in the country/region configuration interface of the TP-Link RE305 V3 allows an unauthenticated attacker on the same LAN to modify wireless regulatory region parameters without authentication. The vulnerable component is the web configuration interface. Successful exploitation forces the device to reapply wireless configuration with parameters from a different regulatory region, resulting in wireless service degradation or unavailability of certain channels.
