Gecko CMS 2.3 Multiple Vulnerabilities
Vendor: JAKWEB
Product web page: http://www.cmsgecko.com
Affected version: 2.3 and 2.2
Summary: Gecko CMS is the way to go, forget complicated, bloated
and slow content management systems, Gecko CMS has been build to
be intuitive, easy to use, extendable to almost anything, running
on all standard web hosting (PHP and one MySQL database, Apache is
a plus), browser compatibility and fast, super fast!
Desc: Gecko CMS suffers from multiple vulnerabilities including
Cross-Site Request Forgery, Stored and Reflected Cross-Site Scripting
and SQL Injection.
Tested on: Apache/2
PHP/5.4.36
Vulnerabilities discovered by Gjoko 'LiquidWorm' Krstic

Cisco Unified Operations Manager is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input.
An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials. Other attacks may also be possible.
This issue is being tracked by Cisco Bug ID CSCtn61716.

Para resolver el laboratorio tenemos que subir un archivo PHP que lea y nos muestre el contenido del archivo /home/carlos/secret. Ya que para demostrar que hemos completado el laboratorio, deberemos introducir el contenido de este archivo.
Además, el servidor está configurado para prevenir la subida de archivos según el Content-Type. Por lo que tendremos que bypasear esta defensa.
En este caso, el propio laboratorio nos proporciona una cuenta para iniciar sesión, por lo que vamos a hacerlo:
Una vez hemos iniciado sesión, nos encontramos con el perfil de la cuenta:
Como podemos ver, tenemos una opción para subir archivo, y concretamente parece ser que se trata de actualizar el avatar del perfil. Vamos a intentar aprovecharnos de esta opción para subir el siguiente archivo PHP:
Antes que nada, vamos a preparar Burp Suite para que intercepte la petición:
Una vez tenemos Burp Suite listo junto al proxy, seleccionamos el archivo y le damos a “Upload”:
Aquí Burp Suite interceptará la petición de subida del archivo:
Vamos a mandar la petición al repeater para tratar con ella mejor, para ello, pulsamos Ctrl R.
Una vez en el repeater, cuando le damos a “Send”, podemos ver la respuesta a la subida del archivo por parte del servidor:
En este caso, indica que los archivos cuya cabecera Content-Type sea application/x-php no están permitidos. Y que solo están permitidos los que sea image/jpeg o image/png.
Sabiendo el tipo de restricción que nos está implantando el servidor, simplemente podemos cambiar el Content-Type de nuestra petición:
Con esto, el contenido del archivo no cambia, y tampoco afectará a que se interprete. Con este cambio, volvemos a intentar la subida del archivo:
Esta vez vemos que se ha subido correctamente. Podemos ver esta respuesta en el navegador de la siguiente forma:
Una vez llegados aquí, ya podemos desactivar el Burp Suite, ya que no haremos más uso de él.
Con esto, volvemos a nuestro perfil.
Ahora, si nos fijamos en el perfil, podemos ver como el avatar ha cambiado, y ahora muestra un fallo de que no carga bien la imagen:
Dándole click derecho, podemos irnos a la ruta directa de la imagen para ver si se trata de nuestro archivo PHP:
Efectivamente, el archivo PHP que hemos subido se ha almacenado como el archivo del avatar, por eso no cargaba en el perfil, intentaba cargar una imagen cuando no lo era. Al visitar el archivo PHP, se ha interpretado el código que hemos colocado, y conseguimos leer el archivo secret.
Habiendo leído este archivo, ya simplemente entregamos la respuesta:
Y de esta forma, completamos el laboratorio:
