Descriptions

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.

Los instaladores de InstallBuilder Qt creados con versiones anteriores a la 22.10 intentan cargar archivos DLL desde el directorio principal binario del instalador cuando muestran ventanas emergentes. Esto puede permitir que un atacante coloque una DLL maliciosa en el directorio principal del instalador para permitir la ejecución de código con los privilegios del instalador (cuando la ventana emergente activa la carga de la librería). La explotación de este tipo de vulnerabilidades generalmente requiere que un atacante tenga acceso a una máquina vulnerable para instalar la DLL maliciosa.
