I just called AT&T support, and the woman I talked to has never heard
of Linux, shellshock, or bash.  So I guess there is nothing I can do.


I did find the source code for the NVG589 Motorola modem/router, and it
does use Linux and bash.

From Sourceforge:

The NVG589 is built on various different flavors of Linux.  The NVG589
has been built on Fedora Core 11 and greater and Ubuntu 9.04 and greater.

If using Ubuntu, make sure /bin/sh points to /bin/bash.  (Not /bin/dash)
