Technical Analysis
This vulnerability arises from improper access control in the informSlaveUpdate function of TOTOLINK T6 4.1.5cu.748_B20211015. An unauthenticated attacker can exploit this by sending a specially crafted POST request to the /cgi-bin/cstecgi.cgi endpoint, triggering mesh slave update coordination without authorization.
