DESCRIPTION:
Craig Heffner has reported a security issue in multiple D-Link DIR
routers, which can be exploited by malicious people to bypass certain
security restrictions and compromise a vulnerable device.

The security issue is caused due to the device not properly
restricting access to the "bsc_lan.php" script. This can be exploited
to access the administrative interface by setting the "NO_NEED_AUTH"
parameter to "1" and "AUTH_GROUP" parameter to "0" in web requests.

This may be related to vulnerability #5:
SA33692

SOLUTION:
Restrict access to trusted hosts only (e.g. via network access
control lists).
