MS07-029 Microsoft DNS RPC Service extractQuotedChar() Overflow (SMB)



This module exploits a stack buffer overflow in the RPC interface of the Microsoft DNS service. The vulnerability is triggered when a long zone name parameter is supplied that contains escaped octal strings. This module is capable of bypassing NX/DEP protection on Windows 2003 SP1/SP2. This module exploits the RPC service using the \DNSSERVER pipe available via SMB. This pipe requires a valid user account to access, so the SMBUSER and SMBPASS options must be specified.

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/windows/smb/ms07_029_msdns_zonename
msf exploit(ms07_029_msdns_zonename) > show targets
msf exploit(ms07_029_msdns_zonename) > set TARGET < target-id >
msf exploit(ms07_029_msdns_zonename) > show options
    ...show and set options...
msf exploit(ms07_029_msdns_zonename) > 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.
