        This module exploits an unicode SEH based stack buffer overflow in Achat v0.150. By
        sending a crafted message to the default port 9256 it's possible to overwrites the
        SEH handler. Even when the exploit is reliable it depends of timing since there are
        two threads overflowing the stack in the same time. This module has been tested on
        Windows XP SP3 and Windows 7.

Advisory: Cross-Site Scripting in IBM Endpoint Manager Relay Diagnostics
          Page

During a penetration test, RedTeam Pentesting discovered that the IBM
Endpoint Manager Relay Diagnostics page allows anybody to persistently
store HTML and JavaScript code that is executed when the page is opened
in a browser.


Details
=======

Product: IBM Endpoint Manager
Affected Versions:  9.1.x versions earlier than 9.1.1229,
                    9.2.x versions earlier than 9.2.1.48
Fixed Versions: 9.1.1229, 9.2.1.48
Vulnerability Type: Cross-Site Scripting
Security Risk: medium
Vendor URL: http://www-03.ibm.com/software/products/en/endpoint-manager-family
Vendor Status: fixed version released
Advisory URL: https://www.redteam-pentesting.de/advisories/rt-sa-2014-013
Advisory Status: published
CVE:  CVE-2014-6137
CVE URL: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-6137


Introduction
============

IBM Endpoint Manager products - built on IBM BigFix technology - can
help you achieve smarter, faster endpoint management and security. These
products enable you to see and manage physical and virtual endpoints
including servers, desktops, notebooks, smartphones, tablets and
specialized equipment such as point-of-sale devices, ATMs and
self-service kiosks. Now you can rapidly remediate, protect and report
on endpoints in near real time.

(from the vendor's homepage)


More Details
============

Systems that run IBM Endpoint Manager (IEM, formerly Tivoli Endpoint
Manager, or TEM) components, such as TEM Root Servers or TEM Relays,
typically serve HTTP and HTTPS on port 52311. There, the server or relay
diagnostics page is normally accessible at the path /rd. That page can
be accessed without authentication and lets users query and modify
different information. For example, a TEM Relay can be instructed to
gather a specific version of a certain Fixlet site by requesting a URL
such as the following:

http://tem-relay.example.com:52311/cgi-bin/bfenterprise/
  BESGatherMirrorNew.exe/-gatherversion
  ?Body=GatherSpecifiedVersion
  &url=http://tem-root.example.com:52311/cgi-bin/bfgather.exe/actionsite
  &version=1
  &useCRC=0

The URL parameter url is susceptible to cross-site scripting. When the
following URL is requested, the browser executes the JavaScript code
provided in the parameter:

http://tem-relay.example.com:52311/cgi-bin/bfenterprise/
  BESGatherMirrorNew.exe/-gatherversion
  ?Body=GatherSpecifiedVersion
  &version=1
  &url=http://"><script>alert(/XSS/)</script>
  &version=1
  &useCRC=0

The value of that parameter is also stored in the TEM Relay's site list,
so that the embedded JavaScript code is executed whenever the
diagnostics page is opened in a browser:

$ curl http://tem-relay.example.com:52311/rd
[...]

<select NAME="url">
[...]
    <option>http://"><script>alert(/XSS/)</script></option>
</select>


Proof of Concept
================

http://tem-relay.example.com:52311/cgi-bin/bfenterprise/
  BESGatherMirrorNew.exe/-gatherversion
  ?Body=GatherSpecifiedVersion&version=1
  &url=http://"><script>alert(/XSS/)</script>
  &version=1
  &useCRC=0


Fix
===

Upgrade IBM Endpoint Manager to version 9.1.1229 or 9.2.1.48.


Security Risk
=============

As the relay diagnostics page is typically not frequented by
administrators and does not normally require authentication, it is
unlikely that the vulnerability can be exploited to automatically and
reliably attack administrative users and obtain their credentials.

Nevertheless, the ability to host arbitrary HTML and JavaScript code on
the relay diagnostics page, i.e. on a trusted system, may allow
attackers to conduct very convincing phishing attacks.

This vulnerability is therefore rated as a medium risk.

Shellshock Attack

HACKER · %s · %s

Shellshock es una vulnerabilidad asociada al CVE-2014-6271 que salió el 24 de septiembre de 2014 y afecta a la shell de Linux «Bash» hasta la versión 4.3. Esta vulnerabilidad permite una ejecución arbitraria de comandos.
Índice:
Origen de Shellshock Shellshock Remoto Ejemplo de Explotación Remota Referencias Origen de Shellshock
La vulnerabilidad se originaba porque antes, a la hora de asignar una variable de entorno, bash te daba la posibilidad de asignar una función. Lo que ocurría cuando asignabas una función en el valor de una variable de entorno es que bash no se detenía en la propia definición, sino que continuaba y ejecutaba los comandos que se pusieran después de la definición de la función.
Literalmente tú después de leer este párrafo:
Ahora todo quedará más claro. Lo que ocurría antes es que tú podías declarar una función en una variable de entorno. Y ocurría un bug, que hacía que se ejecutara el comando que se colocase después. Por ejemplo, tú definías la siguiente funcion en la variable:
variable='() { contenido de la función;}; ‘ Y en vez de simplemente definirse, el bug que tenía bash ocasionaba que se ejecutase el comando que hubiese después de la definición de la función. A nivel de concepto, esto es todo. Para entender mejor esta vulnerabilidad, vamos a ver como funciona el comando env.
Este comando imprime las variables de entornos actuales. Pero también se puede usar para ejecutar un comando en un entorno con una variable especificada. El proceso que hace es el siguiente:
env empieza un nuevo proceso Modifica el entorno de este nuevo proceso Ejecuta el comando que hemos dicho en el entorno creado Por ejemplo, si pasamos como argumento el comando env para que se ejecute en el entorno que te crea el primer env, podremos ver las variables de entorno del contexto que crea el primer env:
Digamos que lo que está ocurriendo es:
«Oye, créame un entorno completamente limpio de variables de entorno. En este entorno la única variable de entorno que habrá será la que yo pase como argumento. Y dentro de este entorno, ejecútame el comando que digo, en este caso, env, para poder ver las variables de entorno del entorno que acabo de crear con el primer env, que al ser un entorno limpio, solo estará la variable de entorno que yo he pasado como argumento».
Ok, ahora estás así:
Es normal, simplemente vuelve a leer el párrafo de arriba despacito y con buena letra.
Ahora bien, sabiendo esto, es aquí donde entra en juego el bug del que hemos hablado al principio, Shellshock. Si nosotros definimos la siguiente función en una variable:
mi_funcion='() { :;}; echo «ES VULNERABLE» ‘  No debería de pasar nada. Sin embargo, si probamos a definir esta función en una variable de una nueva shell de bash (nuevo proceso):
Se ejecuta, a pesar de que solo estamos definiendo una variable de entorno. Esto ocurre porque la nueva shell (el nuevo proceso) ve una variable de entorno que empieza por () y obtiene el nombre de la variable para ejecutarla y definir la función en el entorno. Sin embargo, como ya se ha dicho, el bug hacía que se ejecutase lo que se pusiera después de la función.
En un sistema no vulnerable, ejecutando el comando de la imagen de arriba, simplemente no pasará nada:
Y todo esto que he explicado es el bug y la famosa vulnerabilidad. Puedes pensar, oye, no es para tanto, porque al final, es un simple OS command injection en Linux.
Shellshock Remoto
Lo turbio de esta vulnerabilidad es que se puede explotar remotamente, por ejemplo, en un servidor web, ocasionando un Remote Command Execution (RCE). Los archivos susceptibles a un ataque Shellshock son los que comúnmente pertenezcan a alguna de las siguientes extensiones:
cgi sh Algunos servidores web, como por ejemplo apache, soportan lo que se llama Common Gateway Interface (CGI). Esta característica permite a programas externos, hacer uso de datos provenientes del servidor web. Esta funcionalidad se relaciona con la famosa carpeta cgi-bin que nos podemos encontrar muchas veces. Cgi-bin es una carpeta creada automáticamente para colocar scripts que queramos que interactúen con el servidor web.
Por lo que la explotación remota no se limita a los archivos .cgi. Se limita, a los archivos que interactúen con la bash usando en variables de entorno, datos del servidor web. Que es lo que permite el CGI.
Entonces, la idea de la explotación remota es que cualquier información recibida en una petición por parte del cliente como puede ser el User-Agent, Referer, u otros parámetros se almacenan en forma de variables de entorno para que puedan ser usadas por programas o scripts externos, por esto, los archivos situados en la carpeta cgi-bin son susceptibles a Shellshock.

Estas variables de entorno, al tratarse al fin y al cabo de cabeceras cuyo valor podemos editar, pues lo tenemos todo. Por un lado, tenemos variables de entorno las cuales podemos controlar su contenido, y, por otro lado, tenemos la ejecución en bash de scripts que hacen uso de las variables de entorno que nosotros controlamos.
Si nosotros alterásemos el valor del User-Agent y lo sustituyéramos con un payload como el que hemos visto previamente. Estaría ocurriendo todo lo que hemos explicado. Una función definida en una variable de entorno, al pasarla al contexto de un nuevo entorno de un proceso de bash, ejecutará cualquier comando que se le ponga después de la declaración de la función.

Ejemplo de Explotación Remota
Vamos a ver como sería la explotación usando la máquina «Shocker» de HackTheBox.
Lo primero de todo es identificar el archivo que puede ser vulnerable, en este caso, es user.sh:

Una vez identificado es tan sencillo como enviar el payload característico de shellshock a través de alguna cabecera, por ejemplo, el User-Agent:
curl -H ‘User-Agent: () { :;}; echo; echo ¿Es vulnerable?’ ‘http://10.10.10.56/cgi-bin/user.sh’ También podemos comprobar con otra cabecera, por ejemplo, el Referer:
Podemos observar que en ambos casos se nos ha ejecutado la cadena del segundo echo. De esta forma, acabamos de verificar que es vulnerable. Por lo que ya prácticamente tenemos RCE, si queremos confirmarlo aún más, podemos probar a mandarnos paquetes ICMP:
También podríamos mandarnos una reverse shell:
La explotación de esta vulnerabilidad realmente es tan sencillo como esto, colocar el payload clásico y boom, RCE.
