    Thanks for the reply Steven. I resetted the password yesterday with the mentioned method. It was the same procedure after installing the patch before.

    Is it true, that the current status of the firmware is not to use special charaters? If so, why don't ZyXEL also modified the webpage (user administration), where a user can enter a new password?

    @masterflai,
    We will fix it in next official firmware to forbid user can modify the new password include special characters !  #  $  %  &  (  -  | to cause login issue.

    @Zyxel_Steven : Can you elaborate on that? I don't see how ! ( and - can trigger the bug. But I can trigger the bug without any of the characters you list here:

    wget http://nas520.lan/adv,/cgi-bin/weblogin.cgi --post-data="username=a';touch /tmp/x;'"

    will create a file /tmp/x

    @Zyxel_Steven : In this context, would not a proper input validation be much more useful and the correct way to deal with the threat? In my eyes, prohibiting special characters is at most a workaround to save time.

    Please dear ZyXEL team, do it better this time. You can do it if you try hard.
