PHP Misconfiguration: Missing safe_mode_exec_dir Entry

Abstract

Configurar PHP para que invoque programas arbitrarios puede permitir a los atacantes ejecutar comandos malintencionados.

Explanation

Cuando safe_mode está activado, la opción safe_mode_exec_dir restringe la ejecución de comandos por parte de PHP a los comandos de los directorios especificados. Aunque la ausencia de una entrada safe_mode_exec_dir no supone una vulnerabilidad de seguridad en sí misma, los atacantes pueden aprovechar esta indulgencia añadida junto con otras vulnerabilidades para realizar acciones más peligrosas.
