Description

This module exploits a use after free vulnerability in Mozilla Firefox 3.6.16. An OBJECT Element mChannel can be freed via the OnChannelRedirect method of the nsIChannelEventSink Interface. mChannel becomes a dangling pointer and can be reused when setting the OBJECTs data attribute. (Discovered by regenrecht). This module uses heapspray with a minimal ROP chain to bypass DEP on Windows XP SP3. Additionlay, a windows 7 target was provided using JAVA 6 and below to avoid aslr.

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.
