## Vulnerable Application
|
||||
|
||||
* IBM Downloads page: https://developer.ibm.com/messaging/mq-downloads/
|
||||
* Tested on IBM MQ 7.5, 8 and 9
|
||||
* Usage:
|
||||
* Download and install MQ Server
|
||||
* Create a new Queue Manager
|
||||
* Create a new channel (without SSL)
|
||||
* Run the module
|
||||
|
||||
## Verification Steps
|
||||
|
||||
Example steps in this format (is also in the PR):
|
||||
|
||||
1. Install IBM MQ Server 7.5, 8, or 9
|
||||
2. Start msfconsole
|
||||
3. Do: ```use auxiliary/scanner/misc/ibm_mq_channel_brute```
|
||||
4. Do: ```set channels_file <channel_list_file>```
|
||||
5. Do: ```set rhosts <target_IP>```
|
||||
6. Do: ```set rport <port>```
|
||||
7. Do: ```run```
|
||||
|
||||
Example output:
|
||||
```
|
||||
msf auxiliary(scanner/misc/ibm_mq_channel_brute) > run
|
||||
|
||||
[*] 10.1.1.144:1414 - Found channel: TEST.CHANNEL, IsEncrypted: False, IsMQI: True
|
||||
[*] 10.1.1.144:1414 - Found channel: SYSTEM.ADMIN.SVRCONN, IsEncrypted: False, IsMQI: True
|
||||
|
||||
[+] 10.1.1.144:1414 - Channels found: ["TEST.CHANNEL", "SYSTEM.ADMIN.SVRCONN"]
|
||||
[+] 10.1.1.144:1414 - Unencrypted MQI Channels found: ["TEST.CHANNEL", "SYSTEM.ADMIN.SVRCONN"]
|
||||
|
||||
[*] Scanned 1 of 1 hosts (100% complete)
|
||||
[*] Auxiliary module execution completed
|
||||
|
||||
```
|
||||
|
||||
## Options
|
||||
|
||||
**The CHANNELS_FILE option**
|
||||
|
||||
This option should contain the path to a text file which contains a list of channel names that will be checked. One channel name per line.
|
||||
|
||||
## Scenarios
|
||||
|
||||
This module can be used to identify a list of channel names that are configured on the Queue Manager. Additionally, the module will return whether each identified channel uses SSL and if it MQI type.
|
||||
After obtaining a list of valid channel names, these can be used to further enumerate the MQ installation. For example, the ibm_mq_enum module can be executed using a valid channel name in order to obtain information regarding the Queue Manager.
