Fiyo CMS 2.0.6.1 allows remote authenticated users to gain privileges via a modified level parameter to dapur/ in an app=user&act=edit action.

Weakness

A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).
