Samsung NET-i Viewer Multiple ActiveX BackupToAvi() Remote Overflow



This module exploits a vulnerability in the CNC_Ctrl.dll ActiveX control installed with the Samsung NET-i viewer 1.37. Specifically, when supplying a long string for the fname parameter to the BackupToAvi method, an integer overflow occurs, which leads to a posterior buffer overflow due to the use of memcpy with an incorrect size, resulting in remote code execution under the context of the user.

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