Cisco DPC3941B is publicly accessable on the internet despite bridge mode

I discovered an odd issue with a comcast business connection in San Fransisco.  They have a Comcast provided Cisco DPC3941B currently configured for bridge mode that is receiving a publicly reachable 24.X.X.X address.  They are also recieving a 50.X.X.X address for the single device plugged into this router.

 

Anyone who scans/stumbles across the 24.X.X.X address is able to log in using the standard comcast "cusadmin" account and completely control the router.  Is this expected behavior?

Hello Grumpysysop,

 

Can you please send me a private message with the account number of the location in question so we can investigate? 

 

Thank you
