That's a cross-site scripting vulnerability at its finest. Are you asking how to prevent this on a design level? Never trust user-supplied data.

It's not clear what values for p you want to continue to allow, but the basic principle should be "deny everything except a well-known set" and so a simple implementation would be to default to accueil.html unless p is one from a small set of other pages you want to allow. (A simple but, on the face of it, reasonably safe generalization would be to only allow values for p which do not contain any slash, encoded or otherwise. But "encoded or otherwise" can constitute a large security hole, too. Are you sure you know all the ways a slash could end up as the result of URL parsing?)
