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.

Remote
Severity Level:
===============
High
Technical Details & Description:
================================
1.1
A local file include web vulnerability has been discovered in the official Foxit MobilePDF v4.4.0 iOS mobile web-application.
The local file include vulnerability allows remote attackers to unauthorized include local file/path requests or system specific
path commands to compromise the mobile web-application.
The vulnerability is located in the `filename` value of the wifi interface `upload` module. Local attackers are able to manipulate the
wifi web interface by usage of the vulnerable `upload` POST method request. The service does not encode or parse the `filename` context
on uploads. Attackers can include an existing local application path or an existing local device path as source in connection with script
code to compromise the iOS app. The execution of unauthorized local file or path request occurs in the index of documents module of the
wifi file service application after the inject. The request method to inject is POST and the attack vector is located on the application-side
of the affected iOS application.
The security risk of the local file include web vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 6.9.
Exploitation of the local file include web vulnerability in the upload module requires no user interaction or privileged web-application user account.
Successful exploitation of the local file include web vulnerability results in mobile application compromise or compromised device components.
Vulnerable Method(s):
[+] POST
Vulnerable Module(s):
[+] Upload
Vulnerable Parameter(s):
[+] filename (name)
Affected Module(s):
[+] Index of Documents (http://localhost:8888)
1.2
An arbitrary file upload web vulnerability has been discovered in the official Foxit MobilePDF v4.4.0 iOS mobile web-application.
The arbitrary file upload issue allows remote attackers to upload files with multiple extensions to bypass the system validation and compromise the web-server.
The vulnerability is located in the filename value of the `upload` file module. Remote attackers are able to upload a php or js web-shell by a rename of the
filename with multiple extensions in the upload POST method request. The attacker uploads for example a web-shell with the following name and extension
`pentest.png.html.php.js.aspx.png`. After the upload the attacker needs to open the file in the wifi web-application interface. He deletes the .png file
extension and can access the webshell with elevated access rights to execute.
The security risk of the arbitrary file upload web vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 6.6.
Exploitation of the arbitrary file upload web vulnerability requires no user interaction or privilege application user account with password.
Successful exploitation of the arbitrary file upload vulnerability results in unauthorized file access (aap/device) and compromise of http web-server.
Request Method(s):
[+] [POST]
Vulnerable Module(s):
[+] Upload
Vulnerable Parameter(s):
[+] filename (multiple extensions)
Affected Module(s):
[+] Index of Documents (http://localhost:8888)
Proof of Concept (PoC):
=======================
1.1
The local file include vulnerability can be exploited by remote attackers without privileged application user account or user interaction.

Solution - Fix & Patch:
=======================
1.1
The file include vulnerability can be paütched by a secure parse and encode of the vulnerable `filename` value in the upload POST method request.
Restrict the filename input and filter with an own set exception to prevent application-side attacks.
Parse also in the Index of Documents the vulnerable name output value to solve the issue.
1.2
Restrict the vulnerable `filename` value and implement a secure filter mechanism with own exception to prevent the upload of files with multiple extensions.
Restrict the upload folder and disallow the execution of files that are already uploaded.
Security Risk:
==============
1.1
The security risk of the local file include web vulnerability in the upload POSt method request is estimated as high. (CVSS 6.9)
1.2
The security risk of the arbitrary file upload vulnerability in the upload POST method request is estimated as high. (CVSS 6.6)

En este post vamos a estar resolviendo el laboratorio de PortSwigger: “Web shell upload via Content-Type restriction bypass”.
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:

SEC Consult Vulnerability Lab Security Advisory < 20150113-1 >
=======================================================================
title: Privilege Escalation & XSS & Missing Authentication
product: Ansible Tower
vulnerable version: <=2.0.2
fixed version: >=2.0.5
impact: high
homepage: http://www.ansible.com/tower
found: 2014-10-15
by: Manuel Hofer
SEC Consult Vulnerability Lab
https://www.sec-consult.com
=======================================================================
Vendor description:
-------------------
"Ansible Tower is the easy-to-use UI and dashboard and REST API for Ansible.
Centralize your Ansible infrastructure from a modern UI, featuring role-based
access control, job scheduling, and graphical inventory management. Tower's
REST API and CLI make it easy to embed Tower into existing tools and processes.
Tower now includes real-time output of playbook runs, an all-new dashboard and
expanded out-of-the-box cloud support."
source: http://www.ansible.com/tower
Business recommendation:
------------------------
Attackers are able to elevate privileges and gain full control over Ansible
Tower and therefore access to sensitive data of other customers.
It is assumed that further vulnerabilities exist as only a short crash test has
been performed. Therefore it is recommended to perform a thorough security
review by security professionals.
Vulnerability overview/description:
-----------------------------------
1) Privilege Escalation
Ansible Tower provides the feature to create multiple organizations inside
one tower instance. Each organization can have an unlimited number of users
and administrators which are only allowed to perform actions in the context
of their own organization. Due to missing validation of the "is_superuser"
parameter during user creation, organization admins can create superadmin
accounts and therefore elevate their privileges to gain full control of
Ansible Tower.
2) Reflected Cross-Site Scripting
Several parts of the Ansible Tower API have been identified to be vulnerable
against reflected XSS attacks which can be used by an attacker to steal user
sessions.
3) Missing Websocket Authentication / Information Leakage
The Ansible Tower UI uses Websockets to notify clients about recent events.
This part of the application lacks authentication as well as authorization,
leading to internal data about e.g. scheduled events, being leaked to
unauthorized and/or unauthenticated users.
Proof of concept:
-----------------
1) Privilege Escalation (Org-Admin to Superadmin)
Using the following request, a user with administrative privileges limited to an
organization, can create a superadmin account with access to all organizations:
> POST /api/v1/organizations/3/users/ HTTP/1.1
> Host: $host
> Authorization: Token c3f03841403a17ed79753e057167a62144dae7df
> X-Auth-Token: Token c3f03841403a17ed79753e057167a62144dae7df
>
> {"first_name":"Org1admin_superuser","last_name":"Org1admin_superuser",
> "email":"Org1admin_superuser@local.local","organization":3,
> "username":"Org1admin_superuser","password":"Org1admin_superuser",
> "password_confirm":"Org1admin_superuser","is_superuser":"true","ldap_user":""}
2) Reflected Cross-Site Scripting
The following URL parameters have been identified to be vulnerable against
reflected cross-site scripting:
* URL: /api/v1/credentials/, Parameter: order_by
* URL: /api/v1/inventories/, Parameter: order_by
* URL: /api/v1/projects/, Parameter: order_by
* URL: /api/v1/schedules/, Parameter: next_run
* URL: /api/v1/users/3/permissions/, Parameter: order_by
It is likely that similar issues exist in other parts of the application.
3) Missing Websocket Authentication / Information Leakage
An attacker can setup a websocket connection without providing any credentials
as follows. By issuing a GET request to "https://tower:8080/socket.io/1/" the
server responds with the following string:
> 43167469538:60:60:websocket,xhr-multipart,htmlfilonp-polling[...]
The first integer value can further be used to establish a websocket connection:
#~% openssl s_client -verify 0 -connect tower:8080
> GET /socket.io/1/websocket/43167469538 HTTP/1.1
> Host: tower:8080
> Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
> Accept-Language: en-US,en;q=0.5
> Accept-Encoding: gzip, deflate
> Sec-WebSocket-Version: 13
> Origin: https://tower
> Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ==
> Connection: keep-alive, Upgrade
> Pragma: no-cache
> Cache-Control: no-cache
> Upgrade: websocket
>
>
The websocket key seen above, has been taken from the examples of the wikipedia
page on WebSockets (http://de.wikipedia.org/wiki/WebSocket) as it is only used
to verify that the server received and understood the message.
The server responds as follows:
< HTTP/1.1 101 Switching Protocols
< Upgrade: websocket
< Connection: Upgrade
< Sec-WebSocket-Accept: s3pPLMBiTxaQ9kYGzzhZRbK+xOo=
Now that the websocket connection has been established, data that would
otherwise be presented to logged in users to display status updates for "job
related events" inside tower, can now be observed without any authentication.
Following an example of data received through the websocket connection.
> 5::/socket.io/jobs:{"args":{"status":"pending","project_id":56,
> "unified_job_id":61,"event":"status_changed","endpoint":"/socket.io/jobs"},
> "name":"status_changed"}
Even tough no critical information has been identified leaking through the
websocket, this should still be protected with proper authentication and
authorization because it might aid an attacker in conducting further attacks.
Vulnerable / tested versions:
-----------------------------
Ansible Tower version v2.0.2 has been tested which was the most recent version
at the time of discovery.
Vendor contact timeline:
------------------------
2014-10-22: Contacting vendor through security@ansible.com and asking for
cryptographic material in order to securely send advisory.
2014-10-22: Sending unencrypted advisory as requested by vendor.
2014-10-22: Vendor suggests to release a fix prior to 12.12.2014
2014-10-28: Vendor confirms reported vulnerabilities
2014-12-10: Vendor releases fixed Version 2.0.5
2015-01-13: SEC Consult releases security advisory
Solution:
---------
Upgrade to a fixed version of Ansible Tower >= 2.0.5
Workaround:
-----------
For vulnerabilities 1 to 2, no workaround can be applied.
3 can be circumvented by blocking access to TCP port 8080 on your
Ansible Tower installation.
