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/db2/discovery
msf auxiliary(discovery) > show options
    ... show and set options ...
msf auxiliary(discovery) > set RHOSTS ip-range
msf auxiliary(discovery) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(discovery) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(discovery) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(discovery) > 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 simply queries the DB2 discovery service for information. The discovery service is integrated with the Configuration Assistant and the DB2® administration server. Using the discovery method, catalog information for a remote server can be automatically generated in the local database and node directory.

Verification Steps

  1. use auxiliary/scanner/db2/discovery
  2. set RHOSTS [target address range/cidr]
  3. set THREDS [number of threads]
  4. run

Scenarios

DB2 9.07.2 on RHEL 6.9

msf auxiliary(scanner/db2/discovery) > set RHOSTS 192.168.1.25
msf auxiliary(scanner/db2/discovery) > run

[+] Host 192.168.1.25 node name is SERVER02 with a product id of SQL09072
[*] Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed

msf auxiliary(scanner/db2/discovery) >
  • The same output is expected on other versions of DB2, with the correspondent DB2 version at the product ID.
    • Example: DB2 9.07.2 outputs the product ID SQL9072, while DB2 7.02.9 outputs the product ID SQL7029.
