avm fritz!dsl igd control service 2.2.29 - Directory Traversal Information Disclosure

                source: http://www.securityfocus.com/bid/22093/info

The AVM Fritz!DSL IGD Control Service is prone to a remote information-disclosure vulnerability because the application fails to properly sanitize user-supplied input.

Exploiting this issue allows remote, unauthenticated attackers to retrieve the contents of arbitrary files from vulnerable computers with SYSTEM-level privileges. Information harvested may aid in further attacks.
