Incorrect access control in the setRoamingCfg function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to alter roaming behavior via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
AnalysisAI
Unauthenticated remote manipulation of wireless roaming configuration in TOTOLINK T6 firmware 4.1.5cu.748_B20211015 exposes the setRoamingCfg function through /cgi-bin/cstecgi.cgi with no access control enforcement, allowing any network-reachable attacker to overwrite roaming behavior via a crafted POST request. The device performs no authentication check before processing configuration changes through this handler, consistent with a broader pattern of access control failures across multiple TOTOLINK T6 CGI endpoints documented in coordinated disclosure repositories. …
