Home / exploits Telus Actiontec T2200H WiFi Credential Disclosure
Posted on 13 June 2019
Telus Actiontec T2200H with firmware T2200H-31.128L.08 suffers from a credential disclosure vulnerability. An HTTP interface used by wireless extenders to pull the modem's wifi settings uses DHCP client-provided option values to restrict access to this API. By forging DHCP packets, one can access this interface without any authentication and obtain details such as SSID name, encryption type, and WPA/WEP keys. This can be leveraged if an attacker is on the same Layer 2 network as the modem.
