Microsoft SQL Server SQLi SUSER_SNAME Windows Domain Account Enumeration - Metasploit
This page contains detailed information about how to use the auxiliary/admin/mssql/mssql_enum_domain_accounts_sqli metasploit module. For list of all metasploit modules, visit the Metasploit Module Library.
Module Overview
Name: Microsoft SQL Server SQLi SUSER_SNAME Windows Domain Account Enumeration
Module: auxiliary/admin/mssql/mssql_enum_domain_accounts_sqli
Source code: modules/auxiliary/admin/mssql/mssql_enum_domain_accounts_sqli.rb
Disclosure date: -
Last modification time: 2020-09-22 02:56:51 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: http, https
Target network port(s): 80, 443, 3000, 8000, 8008, 8080, 8443, 8880, 8888
List of CVEs: -
This module can be used to bruteforce RIDs associated with the domain of the SQL Server using the SUSER_SNAME function via Error Based SQL injection. This is similar to the smb_lookupsid module, but executed through SQL Server queries as any user with the PUBLIC role (everyone). Information that can be enumerated includes Windows domain users, groups, and computer accounts. Enumerated accounts can then be used in online dictionary attacks. The syntax for injection URLs is: /testing.asp?id=1+and+1=[SQLi];--
Module Ranking and Traits
Module Ranking:
- normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
