CVE-2024-29188 Information

Description

WiX toolset lets developers create installers for Windows Installer the Windows installation engine. The custom action behind WiX’s RemoveFolderEx functionality could allow a standard user to delete protected directories. RemoveFolderEx deletes an entire directory tree during installation or uninstallation. It does so by recursing every subdirectory starting at a specified directory and adding each subdirectory to the list of directories Windows Installer should delete. If the setup author instructed RemoveFolderEx to delete a per-user folder from a per-machine installer an attacker could create a directory junction in that per-user folder pointing to a per-machine protected directory. Windows Installer when executing the per-machine installer after approval by an administrator would delete the target of the directory junction. This vulnerability is fixed in 3.14.1 and 4.0.5.
