Executable installers are vulnerable^WEVIL (case 34): Microsoft's vs-community-*.exe susceptible to DLL hijacking Jul 01 2016 01:32PM
Stefan Kanthak (stefan kanthak nexgo de)
Hi @ll,

the executable installer for Microsoft's Visual Studio 2015
Community Edition, available from <https://www.visualstudio.com/>,
is vulnerable to DLL hijacking: on a fully patched Windows 7 SP1
it loads the following DLLs from its "application directory"
instead of Windows' "system directory":
Version.dll, AppHelp.dll, NTMARTA.dll, CryptSP.dll, RPCRTRemote.dll

Additionally it loads API-MS-Win-Downlevel-ShlWAPI-L2-1-0.dll from
the PATH.

See <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-0148>
or <https://technet.microsoft.com/library/security/MS16-041> and
<https://www.securify.nl/advisory/SFY20160201/_net_framework_4_6_allows_
side_loading_of_windows_api_set_dll.html>
for a similar vulnerability.

stay tuned
