Synology Forget Password User Enumeration Scanner



This module attempts to enumerate users on the Synology NAS by sending GET requests for the forgot password URL. The Synology NAS will respond differently if a user is present or not. These count as login attempts, and the default is 10 logins in 5min to get a permanent block. Set delay accordingly to avoid this, as default is permanent. Vulnerable DSMs are: DSM 6.1 < 6.1.3-15152 DSM 6.0 < 6.0.3-8754-4 DSM 5.2 < 5.2-5967-04

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/scanner/http/synology_forget_passwd_user_enum
msf auxiliary(synology_forget_passwd_user_enum) > show actions
msf auxiliary(synology_forget_passwd_user_enum) > set ACTION < action-name >
msf auxiliary(synology_forget_passwd_user_enum) > show options
    ...show and set options...
msf auxiliary(synology_forget_passwd_user_enum) > 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.
