Description
Potential privilege escalation issue in Revenera InstallShield version 2023 R1 running a renamed Setup.exe on Windows. When a local administrator executes a renamed Setup.exe, the MPR.dll may get loaded from an insecure location and can result in a privilege escalation. The issue has been fixed in versions 2023 R2 and later.
