1. Admin password disclosure (CVE-2016-5649)
A vulnerability is in the 'BSW_cxttongr.htm' page which can allow a remote
attacker to access this page without any authentication. When processed, it
exposes adminas password in clear text before it gets redirected to
absw_vfysucc.cgia. An attacker can use this password to gain administrator
access of the targeted routeras web interface.

will be redirected to the aCongratulations2.htma page, which reveals some
sensitive information such as 2.4GHz & 5GHz Wireless Network Name (SSID)
and Network Key (Password) in clear text.

Affected Models:
