Incorrect access control in the delParentalRules function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to remove parental-control rules via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
AnalysisAI
Improper access control in the delParentalRules handler of the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote unauthenticated attackers delete parental-control rules by sending a crafted POST request to /cgi-bin/cstecgi.cgi. The action requires no authentication (PR:N) and is automatable, though EPSS is low (0.18%) and there is no public exploit identified at time of analysis. …
