InstallBuilder Qt installers built with versions previous to 22.10 try to load DLLs from the installer binary parent directory when displaying popups. This may allow an attacker to plant a malicious DLL in the installer parent directory to allow executing code with the privileges of the installer (when the popup triggers the loading of the library). Exploiting these type of vulnerabilities generally require that an attacker has access to a vulnerable machine to plant the malicious DLL.
The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors.
