Shell en Huawei HG630
« en: 11-08-2014, 21:24 (Lunes) »
Hola, conseguí por unos pocos pesos un Huawei HG630, el hardware de dicho router es interesante para ser que lo distribuye una operadora acá en Argentina, por lo que pude apreciar, tiene 16MB de flash, 64MB de ram, 400MHz de micro y aparentemente doble nucleo.
Ahora, el firmware es el peor que vi en mi vida, son unos...  :-X
No hay forma de conectarse por telnet, ssh. No hay forma de ejecutar un comando desde la web.
Logré conectarme por puerto serie, pero la shell también esta bloqueada!!!
Lo peor de todos es que el CFE está modificado para que no ande ningún comando, ni siquiera el comando "r" para botear.
Todo esto me produce una bronca excesiva ya que el hardware es de uno, no de la empresa, y encima utilizan un 99% de software libre.
Alguien sabe como puedo obtener una shell en este router? Ya intenté inyectar código salteandome protecciones por java script mediante los cgi, como el clasico cgi para hacer ping, pero no tuve éxito alguno, el "fallo" que tenían otros huawei y que permitía ejecutar comandos en el ping de diagnostico fue solucionado, incluso pude apreciar como dejaron codigo viejo y adaptaron el anterior para solucionar ese "bug".
Les dejo un bootlog por puerto serie por si a alguien le interesa.
Ah! Y aparentemente agregaron una capa extra de "seguridad" para hacer el upgrade de firmware porque no consigo colocarle ningún otro firmware!
Si alguien puede ayudarme seria genial!  ;D

Por casualidad no tendrás una foto de la placa?, me gustaría comprobar si se parece a este otro router

http://wiki.openwrt.org/toh/huawei/hg658bc

El HG630 es interesante ya que, es el único BCM63168 que por ahora vi que usa una flash SPI, esto podría abrir alguna puerta para desbrickear otros routers BCM63168 con una flash NAND, pero que tienen posibilidad de soldar un flash SPI.

Si tuvieseses un backup de la flash también sería interesante, para extraer el bootloader por ejemplo.

NO! si el firmware de porquería no me dejó hacer nada!!! no pude obtener acceso al shell. y no tengo lector de memorias.
fotos no tengo, estuve 3 días tratando de encontrar algun bug explotable, me frustré y lo regalé :-p

Lástima, parece que hay avances en cuanto lo de habilitar telnet y seguramente busybox. El método según leí consiste en bajar el archivo de configuración del router, desencriptarlo, modificarlo con contraseña nueva y acceso telnet, y subirlo de nuevo al router.

https://hg658c.wordpress.com/2015/03/17/hg658c_configtool/

Incluso sería viable la instalación de OpenWrt, y más sencillo seguramente por tener la flash SPI, de paso como ya dije podría dar pistas para ayudar a desbriquear otros routers como el que recientemente brickeó Noltari, el comtrend VR-3032u.

De todas formas no sé hasta que punto el bootloader de Huawei tendría alguna utilidad, a Huawei le encanta limitar el acceso, o hacer que todo funcione de una forma muy particular y crispante.

No recuerdo siquiera haber podido descargar la configuración jeje. Igual no se si funcionaría con este modelo y si funcionara hay que ver si se podría explotar alguna falla subiendo una configuración modificada, yo probé muchas cosas saltando las protecciones de java script pero no conseguí nada, igual, tampoco soy experto en ese campo. Y de obtener root hay que ver si se puede escribir un nuevo CFE  ;D

Buenas, jugando con el HG630, y un poco de san google, pude entrar en la shell de este router, sin hacer nada raro..

1- Entrar como admin a la pagina del router (http://IP_DEL_ROUTER_HG630/admin.html) User: admin   /  Pass:CalVxePV1!

2- En el menu de la izq, Avanzado -> ACL

3- Crear la regla que permita TELNET (Clic en New , Service Type=TELNET ; Access direction = LAN, Las IP's dejar en blanco)

4- Listo , ya entras por telnet a la consola ATP. Te logueas como admin con la misma clave de antes.
