Hi list,

Here is my NSE script for detecting and extracting information
from vulnerable Huawei modems. I know that these modems are
popular in México (Over 2 million devices here), Spain, Italy,
Ecuador and other countries in south america but let me know if
you know other ISPs using them. I also know Colombia have a lot of
them but they have patched versions over there. This vulnerability
was reported a long time ago but ISPs don't seem interested in
fixing it any time soon.

Here is the fixed version. UTF-8 characters got replaced somehow.

I'm wondering if we should use Lua string escapes instead of literal
UTF-8 bytes, to protect against someone using an editor in the future
that changes the encoding. So in place of
        'Modelo de módem:',
use
        'Modelo de m\195\179dem:'.
