QUESTION
I made a post function from c# to send a file to the webserver (php), every file that was uploaded was not filtered by the extension, I was afraid that if there were bad people uploading malicious files such as webshells or other malware into my web server. I only want one extension (.lic) that can be uploaded via the "post" function
...ANSWER
Answered 2019-Feb-17 at 09:43as it was pointed out in a comment - just because a file purports to be of a particular extension does not mean that it necessarily is of that type. However some filtering can be achieved by doing some processing like the following. Test for extension expected mimetype, size and if each .lic
file has a similar header you can test a portion of the actual file itself - though perhaps a file sha1
or md5
checksum might be of use too.
