| * Make use of code signing infrastructure or AppLocker. | * Always specify the fully qualified path when the library location exe from your 'Downloads' directory.Īlmost all executable installers (and self-extractors as well as 'portable' applications too) for Windows have a well-known (trivial, trivial to detect and trivial to exploit) vulnerability: they load system DLLs from their 'application directory' (or a temporary directory they extract their payload to) instead of '%SystemRoot%System32'. Download 'FortiClientOnlineInstaller.exe' and save it in your 'Downloads' directory.ģ. Create a malicious 'dwmapi.dll' file and save it in your 'Downloads' directory.Ģ.

This may helpĪttacker to successfully exploit the system if user creates shell as a DLL. And it allows an attacker to load this DLL file of the attacker as choosing that could execute arbitrary code without the user's knowledge.Īttacker can exploit this vulnerability to load a DLL file of theĪttacker's choosing that could execute arbitrary code. FortiClient 5.2.7 FortiClientSetup5.2.7 32 bits FortiClientSetup5.2. The vulnerability exists due to some DLL file is loaded by 'FortiClientOnlineInstaller.exe' improperly.
