Reino: Security Features

La seguridad de un software no es un software de seguridad. Nos preocupamos de cuestiones como la autenticación, el control de acceso, la confidencialidad, la criptografía y la gestión de privilegios.

Cookie Security: Overly Broad Domain

Abstract
Una cookie con un dominio demasiado grande expone una aplicación a los ataques a través de otras aplicaciones.
Explanation
A menudo, los desarrolladores configuran las cookies para que se activen en un dominio básico como ".example.com". Esto expone la cookie a todas las aplicaciones web del dominio básico y los subdominios. Puesto que es frecuente que las cookies porten información confidencial como identificadores de sesión, compartir las cookies entre aplicaciones puede provocar que una vulnerabilidad de una aplicación comprometa a otra.

Ejemplo 1:
Suponga que tiene una aplicación segura implementada en http://secure.example.com/ y que la aplicación define una cookie de ID de sesión con un dominio ".example.com" cuando los usuarios inician sesión.

Por ejemplo:

HttpCookie cookie = new HttpCookie("sessionID", sessionID);
cookie.Domain = ".example.com";


Supongamos que tiene otra aplicación menos segura en http://insecure.example.com/ que contiene una vulnerabilidad Cross-Site Scripting. Cualquier usuario autenticado en http://secure.example.com que acceda a http://insecure.example.com corre el riesgo de exponer su cookie de sesión de http://secure.example.com.

Además de leer una cookie, los atacantes podrían realizar un ataque de Cookie Poisoning utilizando insecure.example.com para crear su propia cookie demasiado grande que sustituya a la cookie de secure.example.com.

Abstract
Una cookie con un dominio demasiado grande expone una aplicación a los ataques a través de otras aplicaciones.
Explanation
A menudo, los desarrolladores configuran las cookies para que se activen en un dominio básico como ".example.com". Esto expone la cookie a todas las aplicaciones web del dominio básico y los subdominios. Puesto que es frecuente que las cookies porten información confidencial como identificadores de sesión, compartir las cookies entre aplicaciones puede provocar que una vulnerabilidad de una aplicación comprometa a otra.

Ejemplo 1:
Imagine que tiene una aplicación segura implementada en http://secure.example.com/ y que la aplicación define una cookie de ID de sesión con un dominio ".example.com" cuando los usuarios inician sesión.

Por ejemplo:

...
NSDictionary *cookieProperties = [NSDictionary dictionary];
...
[cookieProperties setValue:@".example.com" forKey:NSHTTPCookieDomain];
...
NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
...


Supongamos que tiene otra aplicación menos segura en http://insecure.example.com/ y que contiene una vulnerabilidad de Cross-Site Scripting. Cualquier usuario autenticado en http://secure.example.com que acceda a http://insecure.example.com crea un riesgo al exponer su cookie de sesión de http://secure.example.com.

Además de leer una cookie, los atacantes podrían realizar un ataque de envenenamiento de cookies utilizando insecure.example.com para crear su propia cookie demasiado grande que sustituya a la cookie de secure.example.com.

Abstract
Una cookie con un dominio demasiado grande expone una aplicación a los ataques a través de otras aplicaciones.
Explanation
A menudo, los desarrolladores configuran las cookies para que se activen en un dominio básico como ".example.com". Esto expone la cookie a todas las aplicaciones web del dominio básico y los subdominios. Puesto que es frecuente que las cookies porten información confidencial como identificadores de sesión, compartir las cookies entre aplicaciones puede provocar que una vulnerabilidad de una aplicación comprometa a otra.

Ejemplo 1:
Imagine que tiene una aplicación segura implementada en http://secure.example.com/ y que la aplicación define una cookie de ID de sesión con un dominio ".example.com" cuando los usuarios inician sesión.

Por ejemplo:

setcookie("mySessionId", getSessionID(), 0, "/", ".example.com", true, true);


Supongamos que tiene otra aplicación menos segura en http://insecure.example.com/ y que contiene una vulnerabilidad de Cross-Site Scripting. Cualquier usuario autenticado en http://secure.example.com que acceda a http://insecure.example.com crea un riesgo al exponer su cookie de sesión de http://secure.example.com.

Además de leer una cookie, los atacantes podrían realizar un ataque de envenenamiento de cookies utilizando insecure.example.com para crear su propia cookie demasiado grande que sustituya a la cookie de secure.example.com.
