The exploited instance of IE7 probably spawns cmd.exe with the same privilege levels as IE7 in Protected Mode, which means you don't have read/write access to the user or system files. It's still bad because you probably get to harvest all of the saved username/passwords in the browser and capture all input/output from that IE session.
Now in the case of an exploited Firefox 2, you have full read/write permissions to all of the user files which means you get to steal all the user files and/or encrypt them for ransom.

Internet Explorer was running in protected mode with DEP disabled (this is the default Vista setup). It's interesting that the protected mode of IE does not stop the execution of cmd.exe, but it does prevent you from writing to the file system once you get the shell. http://determina.blogspot.com/ Alexander Sotirov Determina Security Research _______________________________________________ Full-Disclosure - We believe in it.
