Description

This module exploits a buffer overflow in VLC media player VLC media player prior to 2.0.0. The vulnerability is due to a dangerous use of sprintf which can result in a stack buffer overflow when handling a malicious MMS URI. This module uses the browser as attack vector. A specially crafted MMS URI is used to trigger the overflow and get flow control through SEH overwrite. Control is transferred to code located in the heap through a standard heap spray. The module only targets IE6 and IE7 because no DEP/ASLR bypass has been provided.

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.
