Jason Edelstein has reported a vulnerability in NetGear WNDRMAC, which can be exploited by malicious people to disclose sensitive information.

The weakness is caused due to the device disclosing the questions and answers for the password reset functionality via unauth.cgi within the returned HTML source code and this can be exploited to gain access to administrative credentials.

Successful exploitation requires a previous, successfully completed password recovery.

NOTE: The vendor disputes the weakness and states that only information from an unsuccessful password recovery attempt is disclosed.

The weakness is reported in versions 1.0.0.22 and prior.

Solution
Restrict network access to the device to trusted hosts only.
