Hi, I found a bug in ZyXEL Prestige 650 HW Routers with Http Remote Administration active.
Exploting this bug, the attacker can reset the router configurantion.
The "/rpFWUpload.html" is not password protected. To exploit this bug you only need write that:
http://[Router ip]/rpFWUpload.html
and click the Reset button.
Sorry if this post is misspelling... but I'm from Spain and my english level is poor...
