Ya.com sufre agujeros de tipo XSS
###################################

La web de Ya.com esta afectada por vulnerabilidades
de tipo cross-site scripting.

Los agjeros se hayan localizados bajo el subdonimio
acceso.ya.com y asi mismo sobre corp.ya.com

Aparte de los aqui mencionados a modo de prueba de
concepto existen algunos mas en algunas otras zonas
dinamicas del portal.

Tras haber intentado en varias ocasiones contactar
con ya.com , en principio ha sido imposible ya que
en su web la una forma de contacto con ellos es
telefonica, y yo no estoy dispuesto a gastarme
mi dinero para reportar fallos en su web;asi pues
me he visto obligado a mandar correos al tum tum
a seguridad, security etc etc @ya.com para ver si
por suerte alguno existia o no ,lo cual veo que no
al no obtener respuesta , o bien simplemente pasan...

Algunos ejemplos de esta explotacion:

Windows Extended file attributes buffer overflow Study II

Windows Extended file attributes buffer overflow Study II
Original:
##########################################################

In a previous article , i write about extended file
attributes:

"A local buffer overflow exists in the windows explorer .
The extended file atributes functions have a small size
of the buffer in 'FileAllInformation(),FileNameInformation'
and other subfunctions in Undocumented functions of NTDLL ,
resulting in a buffer overflow. With a unknow impact."

Original article:

http://lostmon.blogspot.com/2007/06/
buffer-overflow-in-extended-file.html

I Write "this issue could be done in all files"...

Now i go to extend some details moore of my investigation
and the research of this issue.

Look the new vulnerabilities on Microsoft windows GDI and ole32

http://www.securityfocus.com/bid/16167
http://www.securityfocus.com/bid/25207

http://osvdb.org/displayvuln.php?osvdb_id=31886
http://osvdb.org/displayvuln.php?osvdb_id=31887

All PoC and all exploits have some details to study.

All files wen explorer crash ,crashing wen try to look
the extended file atributes of any file (*.jpg,*.doc,*.gif,*.wmf)
How to demostrate it ??

All exploits have some similitudes ....
all crafted files crashing at the same point or at the same properties
this is a litle test/study of those exploits / vulnerabilities


############################################
Testing with filemon and EFA.vbs
############################################


####################
Exploit wmf File
####################

Download BID 16167 exploit and unzip it in c:\test

open filemon and include process explorer.exe
and click in apply.
now open c:\test\ and wen explorer looks the EFA for the wmf
file , crash , or wen put the mouse over...

in the filemon wen the crash is done we have some similar to


Click To full size

filemon mark the overflow in 'FileAllInformation()' function.

another test with the same file :

save EFA_test.vbs and execute it , the windows scripting host
crash wen try to look extended attribute number 9 (Author).

delete the doc file in a dos command line :)

####################
Exploit jpg file
####################

Download BID 25207 exploit and unzip it in c:\test

open filemon and include process explorer.exe
and click in apply.
now open c:\test\ and wen explorer looks the EFA for the jpg
file , crash , or wen put the mouse over...

in the filemon wen the crash is done we have some similar to


Click To full size

filemon mark the overflow in 'FileAllInformation()' function.

another test with the same file :

save EFA_test.vbs and execute it , the windows scripting host
crash wen try to look extended attribute number 9 (Author).

delete the doc file in a dos command line :)

###################
exploit Gif file
###################

save exploit for Gif file in c:\test

open filemon and include process explorer.exe
and click in apply.
now open c:\test\ and wen explorer looks the EFA for the gif
file , crash , or wen put the mouse over...

in the filemon wen the crash is done we have some similar to


Click To full size

filemon mark the overflow in 'FileAllInformation()' function.

another test with the same file :

save EFA_test.vbs and execute it , the windows scripting host
crash wen try to look extended attribute number 9 (Author).

delete the doc file in a dos command line :)

###################
Exploit Doc file
###################

unzip the explorer_crasher.doc in c:\test\
open filemon and include process explorer.exe
and click in apply.
now open c:\test\ and wen explorer looks the EFA for the doc
file , crash , or wen put the mouse over...

in the filemon wen the crash is done filemon mark the
overflow in 'FileAllInformation()' function.

another test with the same file :

save EFA_test.vbs and execute it , the windows scripting host
crash wen try to look extended attribute number 9 (Author).

delete the doc file in a dos command line :)

Description:

A Custom Search Engine is a tailored search experience,
built using Google's core search technology, which
prioritizes or restricts search results based on websites
and pages that you specify, and which can be tailored to
reflect your point of view or area of expertise.

Google Custom search Engine have a flaw that allows a remote
cross site scripting attack.This flaw exists because the
application does not validate The texarea in the wen preview
a invite.This could allow a user to create a specially
invite that would execute arbitrary code in a user's browser
within the trust relationship between the browser and the server,
leading to a loss of integrity.

Go to

http://www.google.com/coop/manage/cse/collaboration?cx=[tokem-of search engine]

and in 'Add a personal note to the invitation' write some javascript
or html code and them click on 'invite preview'
this code is execute...

Also the form convert to hexa with semicoloms to html :


it works transform to html code , but it does not execute it :)

we can try to convert it in decimal values and it show too the
html without execute it.
Only works with 'simple' html

Orange.es Starmedia y latinchat vulnerables a
ataques de tipo Cross-site Scripting.
Articulo original:http://lostmon.blogspot.com/

#################################################

Hace varios dias que intente ponerme en contacto
con el webmaster tanto de starmedia ,orange para
notificarles una serie de vulnerabilidades en sus
paginas.Hasta tres correos en diferentes fechas sin
Obtener ninguna respuesta por parte del grupo.

Estas paginas , estan afectadas por una vulnerabilidad
llamada Cross site scripting,Atraves de la cual se puede
ejecutar codigo html o javascript en el contexto de seguridad
entre el servidor y el usuario cliente.

Asi pues si visitais estas paginas y usais sus servicios
ir con cuidado y comprobar las URL que visitais de las mismas
y que no haya nada extra├▒o en ellas.

se puede llamar a una ventana de privado sin estar en el chat:
y ademas el parametro username de usuario al que abrimos el

ademas las cajas para introducir texto para enviar al canal o
la caja de mensage a enviar en el privado tambien permite el
envio de codigo XSS esperimentando,con los chats , tal vez
sea asi mismo posible enviar codigo XSS a los demas usuarios
( no lo he probado)


############################
Starmedia
##########################

como puede verse en la siguiente url , el caso es el mismo
que en el dominio orange.es.

La estructura web sigue el mismo patron

y posee las mismas vulnerabilidades ( y asi es ).

http://busca.starmedia.com/search?buscar="><script>alert()</script>

tabien esta afectado de la misma manera y al ser el mismo tipo de

tambien posee las mismas vulnerabilidades.
