ZyXEL GS1510-16 Password Extractor



This module exploits a vulnerability in ZyXEL GS1510-16 routers to extract the admin password. Due to a lack of authentication on the webctrl.cgi script, unauthenticated attackers can recover the administrator password for these devices. The vulnerable device has reached end of life for support from the manufacturer, so it is unlikely this problem will be addressed.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/admin/http/zyxel_admin_password_extractor
msf auxiliary(zyxel_admin_password_extractor) > show actions
msf auxiliary(zyxel_admin_password_extractor) > set ACTION < action-name >
msf auxiliary(zyxel_admin_password_extractor) > show options
    ...show and set options...
msf auxiliary(zyxel_admin_password_extractor) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
