I've recently had my server account hacked by someone uploading an asp script and executing it via the web. It deleted loads of files.
I've no explanation as to how the person got the file onto my server in the first place. All my upload pages are behind a log in, and the logs show the person didn't log in to do this.
All my upload pages also denied files such as asp aspx exe so they didn't use my upload pages to get the file on the server.
The only explanation I can come up with is somehow someone submitted a file upload form from their computer directly to the UploadFiles scripts.
Therefore is this possible? If so, I need to modify the script to only allow it to be run by users who have been authenticated by my site using a session value.
Could you tell me which file in UploadFiles that I need to protect so that it cannot be used to uploadfiles by unauthorised users.
