Hi Stefan and all,
See the "CWDIllegalInDllSearchPath" setting introduced with KB2264107 about 5 years ago, after ACROS finally got enough attention for the vulnerability first published as CVE-2000-0854 (that was 15 years ago, but the vulnerability is still present in ALL installation programs): there were^Ware applications that relied^Wy on loading DLLs from the CWD, so Microsoft CAN'T exclude CWD from the PATH. Microsoft can only offer support to exclude the CWD from the DLL search order: developers can call SetDllDirectory(""), administrators can add the global setting "CWDIllegalInDllSearchPath" or add this setting for individual programs.
While we finally did get CVE-2000-0854 the overdue attention, we apparently didn't promote this enough: http://blog.acrossecurity.com/2012/02/downloads-folder-binary-planting.html (presented at Source Boston in 2012). So now you'll have to do it - good luck :) BTW, Stefan, soon you'll be able to create your own patches for these, and many other bugs, with http://0patch.com. You're welcome.
