Description |
|
|
Se ha descubierto una vulnerabilidad en Lighttpd 1.4.18 y anteriores. La vulnerabilidad reside en un error en el módulo “mod_userdir” cuando no está configurada la dirección "userdir.path" se utiliza por defecto la dirección "$HOME". Un atacante remoto podría leer ficheros arbitrarios como por ejemplo el "/etc/passwd" accediendo a una URL especialmente diseñada como por ejemplo una URL con el directorio "~nobody". |
