Description

This module exploits a buffer overflow vulnerability on the UploadControl ActiveX. The vulnerability exists in the handling of the "Attachment_Times" property, due to the insecure usage of the _swscanf. The affected ActiveX is provided by the dwa85W.dll installed with the IBM Lotus iNotes ActiveX installer. This module has been tested successfully on IE6-IE9 on Windows XP, Vista and 7, using the dwa85W.dll 85.3.3.0 as installed with Lotus Domino 8.5.3. In order to bypass ASLR the no aslr compatible module dwabho.dll is used. This one is installed with the iNotes ActiveX.

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/browser/inotes_dwa85w_bof
msf exploit(inotes_dwa85w_bof) > show targets
    ...targets...
msf exploit(inotes_dwa85w_bof) > set TARGET < target-id >
msf exploit(inotes_dwa85w_bof) > show options
    ...show and set options...
msf exploit(inotes_dwa85w_bof) > 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.
