Description

This module exploits a stack based buffer overflow in Ericom AccessNow Server. The vulnerability is due to an insecure usage of vsprintf with user controlled data, which can be triggered with a malformed HTTP request. This module has been tested successfully with Ericom AccessNow Server 2.4.0.2 on Windows XP SP3 and Windows 2003 Server SP2.

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