Unauthenticated configuration disclosure via missing handler authentication
Published Aug 28, 2026 · Updated Aug 28, 2026
Incorrect access control in TOTOLINK T6 4.1.5cu.748_B20211015 allows remote attackers to read remote-management settings. The getRemoteCfg handler accepts a POST to /cgi-bin/cstecgi.cgi with topicurl=getRemoteCfg without checking authentication and returns enablement and port data. Network access to the management interface is sufficient because no authentication is required; disclosure is limited to enablement status and port information.
