Can I make custom application from MIME type?

L4 Transporter


I want to make custom application(or vulnerability) from MIME type.

EXE of MIME Type is 'application/x-msdownload'

So I made two customer applications as the following patterns.

1. application/x\-msdownload

2. \x61 70 70 6c 69 63 61 74 69 6f 6e 2f 78 2d 6d 73 64 6f 77 6e 6c 6f 61 64\x

But FW detected these custom applications which are tried to use many contexts.

What did I mistook? What is wrong?

Hello KC,

Do you have a sample packet capture for above MIME type?

I was doing some research on 'application/x-msdownload' but I don't find any Media type in that format.

What exactly you are trying to create custom application for?
