Yes it seems that it uses SELINUX

That explains a lot.

Selinux provides "security contexts", and everything that a webserver may run is in the server's security context.

This means that it is not allowed to do a whole lot of things, even if the file permissions allow it.

Which in turn means that virtually everything can go wrong.

I'd recommend to write a daemon that runs a normal user, validates it input and executes the program. The CGI script and the daemon can communicate via TCP or named pipes.
