Prior to version 1.8.39, the upgrade component does not validate user input properly, which allows attackers to perform local file inclusion (LFI) via a specially crafted parameter value. In order to exploit the vulnerability, the installer must be unlocked (no `install/lock` file present) and the upgrade script must be accessible (by re-installing the forum via access to `install/index.php`; when the forum has not yet been installed; or the attacker is authenticated as a forum administrator). MyBB 1.8.39 resolves this issue."},{"lang":"es","value":"MyBB es un software de foro gratuito y de código abierto. Antes de la versión 1.8.39, el componente de actualización no validaba correctamente la entrada del usuario, lo que permitía a los atacantes realizar la inclusión local de archivos (LFI) mediante un valor de parámetro especialmente manipulado. Para explotar esta vulnerabilidad, el instalador debe estar desbloqueado (sin el archivo `install/lock` presente) y el script de actualización debe ser accesible (reinstalando el foro mediante el acceso a `install/index.php`; cuando el foro aún no se haya instalado; o el atacante esté autenticado como administrador del foro).
