web application call executable code to serve client req

hi all.

Im would like to know if there is any web application security issue in
doing this.

I have this web application where the web application has a executable
file that will be executed upon clients requests through the web and
produce a output for the client.

Would there be any issues?

There certainly could be.

You'll want to scrub the daylights out of any user-supplied
data/arguments being passed to that executable via any form to make
sure you don't allow the "execute this" web request to allow users to
run arbitrary commands on the system.

And if it's taking arguments supplied by the user, you'll also want to
make sure there aren't any buffer overflow vulnerabilities in that
application via the command line arguments.

Hunt down the OWASP Project and the OWASP guide, open web application
security project.

Chapters 6 15 and 21 will be of most
interest to your work.
