icinga-installer: Icinga Web 2 Installer Exposure

2026-04-09 icinga web 2 PoC Public

Description

Icinga Web 2 installer/setup wizard is publicly accessible. The setup page at /icingaweb2/setup exposes the configuration wizard which guides through full application configuration including database credentials, authentication backends, and admin account creation. While a setup token is required to proceed, the exposure of the installer itself is a serious misconfiguration that signals an incomplete or improperly secured installation.
