Comcast has just been caught in a major security snafu: revealing the passwords of its customers’ Xfinity-provided wireless routers in plaintext on the web. Anyone with a subscriber’s account number and street address number will be served up the Wi-Fi name and password via the company’s Xfinity internet activation service.

Security researchers Karan Saini and Ryan Stevenson reported the issue to ZDnet.
