Descripción |
|
|
Se ha descubierto una vulnerabilidad de directorio transversal en las versiones anteriores a la 2.6.2 (esta última incluida) del demonio rsync, utilizado para transferencia remota de archivos. La explotación de esta vulnerabilidad podría permitir a un atacante remoto escribir archivos fuera del árbol de directorios reservado en un principio para tal efecto. Para poder explotar esta vulnerabilidad el demonio debe ejecutarse en modo lectura/escritura y no debe estar enjaulado en un entorno 'chroot'. |

Solución |
|
|
Como solución temporal se recomienda activar la opción chroot de rsyncd o no utilizar el modo demonio y hacer uso de SSH como canal de transporte.
