Under certain circumstances, when manipulating the Windows registry, InstallBuilder uses the reg.exe system command. The full path to the command is not enforced, which results in a search in the search path until a binary can be identified. This makes the installer/uninstaller vulnerable to Path Interception by Search Order Hijacking, potentially allowing an attacker to plant a malicious reg.exe command so it takes precedence over the system command. The vulnerability only affects Windows installers. En determinadas circunstancias, cuando se manipula el registro de Windows, InstallBuilder usa el comando de sistema reg.exe. • https://blog.installbuilder.com/2021/10/installbuilder-2160-released.html • CWE-427: Uncontrolled Search Path Element •

On Windows, the uninstaller binary copies itself to a fixed temporary location, which is then executed (the originally called uninstaller exits, so it does not block the installation directory). This temporary location is not randomized and does not restrict access to Administrators only so a potential attacker could plant a binary to replace the copied binary right before it gets called, thus gaining Administrator privileges (if the original uninstaller was executed as Administrator). The vulnerability only affects Windows installers. En Windows, el binario del desinstalador se copia a sí mismo en una ubicación temporal fija, que luego es ejecutada (el desinstalador originalmente llamado sale, por lo que no bloquea el directorio de instalación). Esta ubicación temporal no es aleatoria y no restringe el acceso sólo a administradores, por lo que un potencial atacante podría plantar un binario para reemplazar el binario copiado justo antes de que sea llamado, obteniendo así privilegios de administrador (si el desinstalador original fue ejecutado como administrador). • https://blog.installbuilder.com/2021/10/installbuilder-2160-released.html • CWE-330: Use of Insufficiently Random Values •
