Subject: [KIS-2015-10] Piwik <= 2.14.3 (DisplayTopKeywords) PHP Object Injection
 Vulnerability

-----------------------------------------------------------------------
Piwik <= 2.14.3 (DisplayTopKeywords) PHP Object Injection Vulnerability
-----------------------------------------------------------------------


[-] Software Link:

https://piwik.org/


[-] Affected Versions:

Version 2.14.3 and prior versions.	


[-] Vulnerability Description:

The vulnerability is caused by the DisplayTopKeywords() function
defined in the /plugins/Referrers/Controller.php script:

358.	function DisplayTopKeywords($url = "", $api)
359.	{
360.	    // Do not spend more than 1 second fetching the data
361.	    @ini_set("default_socket_timeout", $timeout = 1);
362.	    // Get the Keywords data
363.	    $url = empty($url) ? "http://" . $_SERVER["HTTP_HOST"] ...
364.	    $api = $api . "&url=" . urlencode($url);
365.	    $keywords = @unserialize(file_get_contents($api));

The content retrieved by the "file_get_contents()" function located at the URL defined in
the $api variable is passed directly to the "unserialize()" function at line 365, and this
can be exploited to inject arbitrary objects into the application scope, allowing remote
attackers to carry out Server-Side Request Forgery (SSRF) attacks, to include and execute
arbitrary PHP code, and possibly other attacks. Successful exploitation of this vulnerability
requires the application running with certain configuration settings allowing to manipulate
the value of the $api variable through HTTP headers (like Host or X-Forwarded-Host).


[-] Solution:

Update to version 2.15.0 or later.
