Lansweeper Credential Collector - Metasploit
This page contains detailed information about how to use the auxiliary/gather/lansweeper_collector metasploit module. For list of all metasploit modules, visit the Metasploit Module Library.
Module Overview
Name: Lansweeper Credential Collector
Module: auxiliary/gather/lansweeper_collector
Source code: modules/auxiliary/gather/lansweeper_collector.rb
Disclosure date: -
Last modification time: 2019-11-05 18:32:45 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: ms-sql2000, ms-sql-s, sybase
Target network port(s): 1433, 1434, 1435, 2533, 2638, 9152, 14330
List of CVEs: -
Lansweeper stores the credentials it uses to scan the computers in its Microsoft SQL database. The passwords are XTea-encrypted with a 68 character long key, in which the first 8 characters are stored with the password in the database and the other 60 is static. Lansweeper, by default, creates an MSSQL user "lansweeperuser" with the password is "mysecretpassword0*", and stores its data in a database called "lansweeperdb". This module will query the MSSQL database for the credentials.
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.
