Official description

Potential privilege escalation vulnerability in Revenera InstallShield versions 2022 R2 and 2021 R2 due to adding InstallScript custom action to a Basic MSI or InstallScript MSI project extracting few binaries to a predefined writable folder during installation time. The standard user account has write access to these files and folders, hence replacing them during installation time can lead to a DLL hijacking vulnerability.
