Details

WiX Toolset's .be TEMP folder is vulnerable to DLL redirection attacks that allow the attacker to escalate privileges ### Summary .be TEMP folder is vulnerable to DLL redirection attacks that allow the attacker to escalate privileges. ### Details If the bundle is not run as admin, the user's TEMP folder is used and not the system TEMP folder. A utility is able to monitor the user's TEMP folder for changes and drop its own DLL into the **.be/<bundle>.Local** folder immediately when the .be folder is created. When the burn engine elevates, the malicious DLL receives elevated privileges. ### PoC As a standard, non-admin user: 1. Monitor the user's TEMP folder for changes using ReadDirectoryChangesW 2. On FILE_ACTION_ADDED, check if the folder name is .be 3. Create a folder in .be named after the bundle + .Local (e.g. MyInstaller.exe.Local) 4. Put the malicious COMCTL32.DLL in the .Local folder following the naming used for the real DLL (e.g. MyInstaller.exe.Local/x86_microsoft.windows.common-controls_.../COMCTL32.dll) 5. Do hacker things when the engine escalates and the malicious DLL is loaded Proper naming for the path can be obtained by using GetModuleHandle("comctl32.dll") and GetModuleFileName. ### Impact DLL redirection utilizing .exe.Local Windows capability. This impacts any installer built with the WiX installer framework.
