phpTrafficA Local File Inclusion
------------------------------------------------------------------------


SUMMARY

<http://soft.zoneo.net/phpTrafficA/> phpTrafficA is "a GPL statistical
tool for web traffic analysis, written in php and mySQL. It can track
access counts to your website, search engines, keywords, and referrers
that lead to you, operating systems, web browsers, visitor retention, path
analysis, and a lot more". Input passed to the "file" parameter in "
plotStat.php" and "lang" parameter in "banref.php" is not properly
verified, before it is used to include files. This can be exploited to
include/see arbitrary files from local resources.

* phpTrafficA version 1.4.1
* phpTrafficA version 1.4beta4

Vulnerable Code:
Code found inside phpTrafficA/plotStat.php:
//Vulnerable Code :line 14
if (!isset($file) or $file=="") {$file = $_GET['file'];}
include("./Php/phplot.php");
include("./tmp/".$file);

Code found inside phpTrafficA/plotStat.php:
//Vulnerable Code :line 16
if (!isset($lang) or $lang == "") {
$lang = $_GET["lang"];
if ($lang == "") { $lang = $_POST["lang"];}
}
include ("./Lang/$lang.php");
