Taint mode is not an obstacle to be overcome. It's there
for a good reason, and the administrator of your web server has
required it for a good reason. Depending on the server, it may
even be a matter of required policy.
You should not be attempting to sidestep security measures like this.
If it happened on my server, I'd take strong action
against whoever did this. Don't get frustrated by what
we're saying here, give it some real thought.
