Genexis Platinum-4410 2.1 – Authentication Bypass

Genexis Platinum-4410 v2.1 Home Gateway Router discloses passwords of each users (Admin, GENEXIS, user3) in plain text behind login page source "http://192.168.1.1/cgi-bin/index2.asp". This could potentially allow a remote attacker access sensitive information and perform actions such as reset router, changing passwords, upload malicious firmware, etc.

Mitigation:

Upgrade to a patched firmware version that fixes the authentication bypass vulnerability. Alternatively, restrict access to the router's web interface to trusted IP addresses only.
