Description

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 Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/solaris/samba/lsa_transnames_heap
msf exploit(lsa_transnames_heap) > show targets
    ...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

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
