Subject: Re: SEANux 1.0 remote back door
After discussing this with the SEA, we’ve determined this is a misconfiguration. They are planning on fixing it in the next release.
The fix is simply modifying apache’s ports.conf to bind apache to localhost.
# cat ports.conf |grep -n 127
8:NameVirtualHost 127.0.0.1:80
9:Listen 127.0.0.1:80
Actually one of the fastest vendor responses I’ve ever seen. :-)

But the credentials are set for mysql during setup, and I don't see any other code to run sql queries on the system. Perhaps they just default to root root as that's a very common password combo for mysql installs?
